Pros: Installs easy enough, when it works it seems efficient enough.

Cons: Bloated, works for a while then starts to misbehave, service not running, shields turned off, restarting it works for a bit then starts all over again.

Bottom Line: Have tried it on several occasions, same story works for a bit then screws up. No more trials, end of story.

It gets a 1 star because it wouldn't let me go to a jailbreak link I know is fine, then I uninstalled Avast, it tells me to reboot to finish uninstalling, only for Windows 8 to refuse to boot up again due to a missing file.

Now I get to spend hours reinstalling Windows and everything and lost data over it. Thanks Avast... not.

I should add, if you check the av comparative website, Avast has far more false positives than any of the other software they test.... much higher, not just a few files difference.

Consistently the best in free anti virus reviews. Does not slow my PC down, require very little intervention by the user.
I have tried most of the free ones on several PCs, Avast, Avira, AVG, Panda Baidu, MS security.
To suggest that microsoft essentials is better is just ludicrous. Ok so so you have to deselect a few things when you install it, but lets not forget it's free, so I consider it an extremely small price to pay.

dmathwizard reviewed v8.0.1489 on May 27, 2013

I like Avast because of how quick and good it is. With the Ver 8 update it seems the company is going in the wrong direction but its still faster, and more accurate (third party testing) than the competition. Its also one of the few that have a bootable mode and a command line scanner.

I don't like the layout because not everyone has the patience or understanding of the terms to figure out how to configure it or find that file that flagged as suspicious software. I've noticed some things like Java's offline installer is flagged as suspicious, reputable companies that have been around for a long time yet their certified files are suspicious.

Kudos to Avast on their spyware and spam detection. I wouldn't completely rely on their spyware detection though.


TC17 reviewed v8.0.1489 on May 22, 2013

I don't understand the reason for thie high ratings on this. Yes the antivirus is ok, but this thing is bloated with ads, and ALWAYS trying to get you to buy the stupid program. It also tries to trick you into installing a google bar, and set chrome as your default browser, and its not just during the install, its after EVERY program update. I wouldn't be surprised if this is loaded with spyware also.

Microsoft Security Essentials (or the one built into Windows 8) works much better, with no ads or any of the other crap).


carlo_tor reviewed v8.0.1489 on May 19, 2013

Avast is a good AV and once it was light, too. Now the version is big, complex and slows down my PC. I uninstalled it and adopted Panda Cloud.
I strongly suggest Alwast developpers to make it more essential and lighter.

Some people get way to hung up in "detection" rates. I'm not even sure why you would take the time to do all of that. You can inform Avast! of any false positives and have the issue taken care of. Their data base updates frequently and seamlessly . IMHO, this is the best Free AV out. The rest is just geek talk that means little or nothing in the real world.

Hilbert reviewed v7.0.1473 on Oct 24, 2012

I've a semi-regular AV comparison testing phase and this time I started with AVG 2013 several weeks ago when it appeared on fileforum. I wasn't going to test Avast!, Avira etc. until I had more time but Sativarg's flaming comments got the better of me (so this is just a first look). ;-)

Sativarg's correct, Avast! 7.0.1473 *is infected* with Google parasite-ware but you can stop the contagion from infecting your PC by carefully un-ticking the fine print in the bottom LHS of the opening dialog.

What is also disconcerting is that after installation the 'Summary' tab says the program expires on the 1st Dec 2012--in 30 days. Supposedly a 'free' version but the *very* fine print says registration is essential or it'll go belly-up. As I'd never register a free AV anyway, Avast! will be uninstalled after I've finished testing.

As well as being parasitic-ware, I'd also consider Avast entrapment-ware as after becoming used to it one's get entrapped at the threat of being cut off. If it's demo--as this is--then it should say so upfront--even if the definitions are free.

I normally keep found viruses in a virus directory, and for safe measure I encrypt the infected files against accidental stuff-ups. Having a collection of the critters allows me to do a comparatively good comparison of AV software and it also helps when I'm trying to determine actual viruses from false positives.

However, I've not had time to do that yet, but as the earlier AVG 2013 scan had already cleared a large data disk containing about 600k files, I ran this Avast! test over what AVG had already cleaned. The files that AVG earlier removed as viruses were also tested with this version of Avast!

Quick results: Avast found 68 files that it considers viruses on a disk that AVG had found to be clean. Of these 68 files, I'm pretty certain that only about 12-15 are actually viruses and the rest are false positives. It's too long to explain why, you'll just have to take my word for it--and I'm also quite familiar with these 'false positives': they're the roundup of usual suspects [duh! Sorry Claude].

Nicely, Avast!--whilst well known for its over sensitivity--now ignores other well known false positives that were always picked both by it and other AV software. NirSoft's utilities are now clean in Avast! but AVG still has problems with some of them. Here's a brief list:

AVG 2013

NirSoft, NirLauncher --- detected --- pgm Loggger IAC
NirSoft, Mail PassView --- detected --- pgm HackTool.QUD
NirSoft, LSA Secrets --- detected --- possible Win32/DH{..etc..
Arne Vidstrom Utilities --- 1 detected -- clearlogs --- pgm Hacktool.UHW
Cain & Abel --- not detected --- although it dumps 'LSA Secrets' (good)
Shatter --- detected --- pgm Exploit.AFC (old issue should be ignored now)
Unlocker --- detected --- Adware Generic_c.JV


Avast! 7.0.1473

NirSoft, NirLauncher --- clear --- (good)
NirSoft, Mail PassView --- clear --- (good)
NirSoft, LSA Secrets --- clear --- (good)
Arne Vidstrom Utilities --- 2 detected -- klogger (keylogger) & clearlogs
Cain & Abel -- not detected -- even though it dumps LSA Secrets (good)
Shatter --- detected --- Shatter-B Exploit
Unlocker 1.8.7/9 (some versions) --- eBay adware

Both AVG and Avast! have improved with respect to false positives and this is the best I've seen them. Poor Nir Sofer with his NirSoft Utilities has always taken a beating from AVG and AVG has done stuff-all about over recent years. (If he was as big as M$ then it's certain his utilities would not pop up as false positives.)

I found a disturbing problem in AVG when I was testing the common and very useful Unlocker utility. It's no secret that some versions contained an eBay adware payload, however, when I checked 10 Unlocker files (in 7 versions) grouped altogether from the context menu, AVG found NO adware! Separately--checked as individual files also from the context menu--AVG found that versions 1.8.8 and 1.8.9 both contained adware, whereas Avast! found only advare in version 1.8.7 but it did so in BOTH the individual and grouped scans.

Clearly, there's problems here: AVG is not detecting the adware when the files are group-checked, and both AV programs give different results on different versions of the Unlocker program installation file. This can only be resolved by more AV testing with other programs. I'll check this later with other AV software when I get a chance.

(Seems AVG might have a problem with its scanning algorithm in that it gets confused when it sees a lot of files with the same name inside a group of packed setup .EXEs--probably a 'shortcut' to speed up the scanning process but it miscounts files when many of have the same name(s)--but that's just my hunch.)

Avast! might be sleazeware, and whilst it definitely has problems, it's probably marginally better than AVG. (I normally use AVG because it's one of the few AVs that I can easily tame but Kaspersky and some others are definitely better).

In summary, if you are serious about detecting viruses then you'll always use multiple AV checkers. (Keep or buy one then use demos to see how honest it is.)

A lot of complaints here.. I can understand, yet I used norton and comcast security suite for a long time and it eventually slowed my system down to a crawl. I uninstalled all that crap , got avast and have been using for a couple of months now. Needless to say I think that it is GREAT for free! It does not hog up my system, yes surfing you can tell it is there, yet does it's job well. It is very full featured for free, so for those that complain.. well? all programs have quirks with diff pc's etc. you all know that.. I like it for what it is which is FREE!

On Windows 7 SP1, the file system shield it slowdown the startup and the execution of applications considerably. On a plane Windows 7 (without SP) avast 7 also produce BSODs.
I'm using avast since v4 and I've to tell that this is the most unstable and bloated version I've tried. A shame.

I've liked Avast, it's lightweight and does a decent job
I was moving some things around and wanted to reinstall avast to a different drive. I uninstalled my version and wanted to reinstall it again, which was version 6. Nope, the setup wouldn't let me. Instead it said it was going to download the latest version. I clicked cancel and my system became unresponsive while it continued to download and try and install the latest.

Version 7 might work well by I don't give into forcible intstalls.

EDIT. Decided to give 7 a try and I find it to be far too aggressive. Script files I use in foobar are now blocked so I had to disable the script shield. I also find that this version slows everything down from browsing to opening programs far more than the previous version did.

I'm deeply unimpressed by this release having been an Avast user for years and having always given it 5 stars here. Initially I had some very scary hangs at startup and I've have had to switch off the rootkit scan and set Avast to load after other services to prevent this. Now - because of a rogue update file - Avast will no longer update and can't be repaired or uninstalled. They have promised a fix but have given no proper timeline. I appreciate that Avast is free and generally a very good product, but .... AV programs are crucial to the safe operation of a computer and bugs can cause critical errors. The release of Avast 7 has been a very shoddy and I suspect premature affair, I really hope that Alwil sort this out quickly.

gatorfan95 - Avast is in the 'Hall Of Shame' for installing 'Chrome' with no option to deny installation. Of course Avast get paid for this, that why it's 'free'.

If you don't mind your drive being filled with unwanted programs I suppose it's not a problem.



gatorfan95 reviewed v7.0.1407 on Feb 25, 2012

I don't know if it happens when you download and install it manually, but when I used the "update program" feature while Avast! was running on my PC it installed the Chrome browser on my hard drive without any notification that it was doing so, or an option to decline the installation. Now, while I like Avast!, have used it for years on several machines and will continue to use it, this is screwed up. If I wanted to use Chrome I'd install it. Program rating 5, BS rating minus 1, over all a 4.

@input I said I've used Avast! for years and this is the first time it has done it to me, that's why I brought it up.

And although I disagree with Input Overload on some of his reviews, I have to agree with him on this one.

The best protection is to use DeepFreeze or DeepFreeze-like software, these antiviruses are only resources suckers.

There are some good free programs that are useful. PC security is not one of them, the reason that avast is popular is because there is a free version - That's all.

Some things are worth paying for: AV is one of them, to try & get the free version from the site is getting more difficult, do yourself a favour & buy security software.

Version 7 seems to be running as smoothly as version 6.

This is my favorite free AV. Perhaps the prior reviewer missed the "No Thanks" link on the download page. There's no subterfuge on Avast's part, that's for sure.
I can't imagine what could be better.


asaenz reviewed v7.0.1396 Beta on Feb 8, 2012

When I went to their site and clicked on download free version, a window popped up to offer Pro Version at discounted price and would not close unless I clicked on Yes for Pro Version ... pooor sales practice. Previous version Avast caused BSOD on my computer last time I tried it and I won't risk it for now.
Update: no I didn't miss any obscure links ... there were 3 and 2 didn't function. I was able to install the current version (7) and reboot without a BSOD and I'm trying it out as I type. Would be nice if sandbox defaulted to 'ask' rather then 'automatic' because some things it doesn't recognize need to run with no interference. "Free" version requires registration which gives you approximately 366 days till expiration after which I suppose it converts into some type of "ramsonware" (pay or lose protection).

I had had the free version of Avast! for three years and it worked wonderfully for me, but when I got a new laptop I was coerced into purchasing CA Internet Security. It was the biggest mistake I ever made. My computer was overrun with viruses and had to pay out nearly $300 to get it completely cleaned. I am back to Avast! and have purchased the full version...I have never had a virus slow or cause problems with either of my computers with Avast!, free version or full. My father has also used the free version of Avast! for longer than I with no problems. (We only use our computers within the home for book/song downloads, writing, and a few internet searches when curious on specific topics or online shopping, so I do not know how well Avast! works for bigger internet users.) As far as I can see I'll continue using Avast! until it finally fails out against most viruses, spam, and fake AVs.

I've been using Avast for quite some time, until recently when I updated it. Apparently Avast seems to be getting quite large, in terms of how much space it takes up. I think over 200MB installation for an anti-virus program is a bit much, which is why they could've left certain features I believe are unnecessary fo most home users. With that said, I've switched to Avira which has always worked just as good for me. Avast is greatly recommended, if you don't mind having all the great features, and the huge installation that comes with it.


nailzs reviewed v6.0.1273 Beta on Aug 30, 2011

The new motherboard was an exact replacement of the one I had to RMA. The same hardware was reinstalled. Everything else worked fine. AVAST updated, Comodo updated, Quake 3 Arena worked online, but not the browsers. If there is something to adjust what is it? Even the AVAST forum was no help. The AVAST that was installed and working stopped before the motherboard replacement stopped and the new BETA was installed 3 times, but the browsers didn't work. I installed AVG and now everything works.

Both nilst2006 and that other guy are wrong. Nilst2006, your friend must first configure avast!. It is not idiot proof. Other guy, avast! did not kill your browser on 64bit Windows 7, you did. I know because I've been running avast! pro on 64bit Windows 7 since last tax season, with the latest versions of both ie and ff installed without issue. Nonetheless as I said below, webrep is weak, safe zone is buggy, etc. Good luck.

I wanted to try Avast more thoroughly but it wouldn't install on my system ... some driver conflict I suppose ... I uninstalled 6 other programs to see if it would help but I kept getting a reset towards the finalization of the installation process. I did try it a bit in my VM and that is why I wanted to try it on my main system and I liked it. I was mainly interested in its sandboxing capabilities because I'm searching for an good alternative to Sandboxie, Bufferzone, and Comodo's sandbox.

Alas, I was hopeful that Avast would run well on my system but it didn't ... probably a driver conflict as toward the end of installation my computer would reset and I tried it 2 times with similar results.

I was never a fan of avast many years ago with it's mediocre results and hideous interface.But they really have upped their game and I've been quite happy with it for the last couple of years.

For me the most important thing is not detection rate(which is good) or interface(which has greatly improved) but the impact on my system. Kaspersky while having good detection rates brought my system to a crawl. NOD was good until I realized, thanks to avast, that even that was slowing my system just a bit. Avast is also the lightest on resources, far more than MSE. I've turned notifications and forgotten that it's there, it's impact is that unnoticeable.

So with sensible computing you really can't go wrong with this

Good AV packed with a lot of features. I recently switched back to this after using MSE for more than a year. I missed some of Avast's features. MSE and Avast are actually BOTH very good, but I liked being able to control how often I received updates
Problem was with MSE, when I installed it on someones computer who only turned on their computer every few days, the security center was always warning that defs were out of date and user action was required. Avast simply updates itself immediately after booting.

Avast did let me down only last week, when their newest defs started flagging every html file containing a script as a trojan. The developers fixed the problem within a few Hours though. I still give it a 5, as long as this isn't a common occurrence.

So, to repeat my previous ACCUSATION, YOU HAVE nothing to back your contention that AVAST! is garbage, do you? I doubt you would read any of the comments here and see all the great reviews people have written about AVAST!, what would be the point, HUH? You know everything, and CERTAINLY couldn't learn anything from us peons-RIGHT? During my perusal, you're the only one who had anything bad to say about AVAST! and you don't have ANY PROOF to support your claims! I know, childish anal retentive authoritarian egotists such as yourself, are above having to provide proof to support their stances! Just the fact that you said it, is proof enough in your eyes, huh!?!? And how dare I, question your authority-RIGHT? Especially since you have forgotten more than I'll ever know, RIGHT??

Overly obnoxious, you are an absolute, conceited, pompous boor!!!

Dealing with people such as yourself, is SO beneath my dignity. I have blessed you with my chastisement, and if you won't allow it to compel you into being a better person, well then that's they way it shall be!

I've been using this for over a year now, and I like it much better than Avira, because of all the nice features it has, which you usually have to pay extra for. Nonetheless, I've never had any issues with Avast before, until the I got the most recent update. When that happened, for some reason, Windows 7 had trouble starting, and claimed it had to repair certain files before restoring the last known good restore point. And when it did restart, there were some very odd things happening with Windows. With that said, I went into Safe Mode and uninstalled Avast. I went ahead and reinstalled the 6.0.1000 version and everything went back to normal.

Not sure if this will happen with anyone else, but just putting it out there, that this might be a bit of a bad update from Avast and you may be wise to skip it, if you think it'll cause problems on your computer too.

AVAST! catches say maybe 75% of incoming malware, generally Trojans and those damn fake AV scams. SAS gets maybe 10% and MBAM gets say 5% and probably 10% sneaks in. MBAM's strongest suit is in finding sh&t that gets in, when you scan and ten it is good a removing it.

Overblown, I'd be interested in hearing your experiences with AVAST!, but I'd imagine your too busy over at YouTube, marking all the vids there "FAKE"!

MBAM & SAS both have decent free stand alone fully functional programs, with great support on the freebies. I upgraded on both, out of gratitude for all the great help I got from the support teams at MBAM & SAS! I actually had my own support guy at MBAM, Tom Mercado, who would generally get back to me within an hour. Being self-taught, my learning has finally gotten to the poiunt where I have been able to fix my computer by myself now. I'll bet Tom thinks I've died. Gee, I wonder if he misses me??? Neither MBAM or SAS have realtime protection on the free versions, and that is what differentiates the free from pro versions. SAS has a great "toolkit" of repairs that I have used on many occasions that fixes broken processes after you've been hit. Not sure if the free SAS version it or not.

Hey Overego, why don't you reserve your opinions for things YOU ACTUALLY KNOW ABOUT and have some intimate knowledge from ACTUAL EXPERIENCE??? (Talk about p*ssing in the wind!?!~!!).

Do NOT buy the "Pro" version. The Web Rep module, which as you might guess, checks the reputations of web sites you visit is vote based, which for obvious reasons is unreliable, and sometimes flat out don't work.

The Safe Zone module is definitely under cooked, and the Sandbox module is a pain because the delete button is buried under multiple layers of UI.

The scan is customizable, fast, and probably trustworthy.

Definitely a rush job here, and not worth the 20, or anything for that matter.

Input Overload reviewed v6.0.945 Beta on Feb 4, 2011

Plumber, 'You Think' you haven't' had any infections, I heard that from dozens of people who are using inadequate malware protection. I see you have reviewed 'avast! Free Anti-virus 6.0.945 Beta'.....Beta, now what does that mean, it means you are using an AV that is full of bugs. Hmmmm.

I too frequent 'Wilders Forum' among many others & I don't give a pigs burp who you are. I do know you have an ego thats unwarranted by far.

And yes I always read the changelog when Eset releases an update.

All software has bugs in it, what I was saying i haven't been affected by any. I've tried just about all the AV products & settled on Eset, Prevx & Malwarebytes. I also run Trojan Remover once a week or so.

Recently I've been giving Norton 2011 security suite a run after years of refusing to have a Norton product on any of my systems, it's suprisingly rather good.

Sorry about your bad experiences with Eset, maybe a personality change might help? You could certainly use one.

By the way I do understand English as I am English, no need for 'Dat' etc.

'Killed your CPU' - ROFLAO!


Plumber reviewed v6.0.945 Beta on Feb 3, 2011

Well Input Overload, I wasn't born yesterday either. Haf you ever read any of Eset's release notes when a new version has come out? Dat be where dey put the list of stuff they fixed. In other words, the stuff that was a bug in the previous version. Unless you want to tell me that they've never had to fix anything, you must admit that ESS has had bugs. I've reported many of them publicly, mainly on Wilder's forums, and I'm not going to repeat them here because I don't want anyone figuring out who I am.

I spent lots of time using Eset's products. They work OK at times. But I grew sick of their terrible attitude (not going to explain), and the "advanced heuristics" killed my CPU. Now I've stopped being an idiot, and I get my AV for free. And it works great. Sorry you paid for nothing.

P.S. I've been using Windows since version 3 and have NEVER had active malware on any of my systems. Not even once.

I’ve been using avast for good 10 years and in general no issues, but with this latest update 5.1.889 I can only advice you “Stay away” it’s loaded with bugs that will in some ways mess up your PC if not the same day then days later.
I have several home machines Win 7 x64 out of which only 1 x32 works OK but some time s I tend to lose Wi-Fi, rest of them run on version 5.0.677, but if I won t be able to upgrade from GUI to the latest 6 when its final is release without issues, I’m done for good and no looking back.

4 out of 5 since it's beta and lack some functionalities (will be there in the final version though). As a side note I can't give any anti-virus a 5, but that's cause I voluntarily hunt malware samples for many of them (0-day samples, no AV triggers on them, mostly).

And most importantly; those tests can't tell if one is better than another. It all comes down to if your currently installed AV blocks a particular malware about to be installed on your system.

Plumber reviewed v5.1.889 on Jan 18, 2011

Uninstall Eset, put your debit card and wallet away, and install avast. You will save money and get a much better product. And ironically, you'll also get better support.

Unlike people who are just biased for no reason, I don't believe in faith-based computing. I've used many versions of the grossly-overrated Eset products. Their system impact is excellent, but they're always more riddled with bugs than a crackhouse. Kaspersky is so utterly terrible that I've given it a lifetime ban.

Input Overload reviewed v5.1.889 on Jan 14, 2011

Get your wallet out, remove debit card, hop over to the Eset site, buy Eset AV. This program isn't a patch on Eset or Kaspersky.

Plumber, total absolute unmitigated garbage, I was not born yesterday. I have used Eset, then Eset Smart Security for many years, it has yet to let a virus through, & what bugs specifically did you find as I yet have to find one? Perhaps you will let us know?

If you are going to pay for some software AV & Anti-Malware are the things to go for- Layered protection. That's why in 15 years on the net & 1700 bookmarks & a 50 Meg Bit fiber connection i have had only one worm/virus at large on my PC.... Nuff said. BTW I also paid for Malwarebytes too, worth each & every penny. I spend my working life in comms rooms....

With version 5, the Avast team has taken an excellent product, and made it outstanding. This version is a significant improvement over version 4 in terms of interface and performance.

In my experience, the stability and smoothness of avast! version 5 vastly exceeds that of most competing products, irrespective of price. And with avast!, I don't have 100 false positives driving me nuts every day.

Be very wary of empty, baseless comparisons of the detection capabilities of avast! versus other products.


jim001 reviewed v5.0.594 on Jul 19, 2010

For free without a doubt the best protection, comparable to Norton and probably better but for free! Several shields that even some paid AV's don't provide. Avast gives all around solid protection with very few false positives, rootkit and antispyware protection using little system resources. Consistent reliable updating. Keep in mind I'm saying for a freebie, to pay for an AV Eset or Kaspersky is recommended, and they are about the only AV's paid or free that is superior to Avast. Use Avast with Malwarbytes as a on demand secondary scanner and you'll have rock solid security ....for free!

No replacement for a paid solution because of its detection capabilities? It has the exact same real-time and scanning detection as its for-pay versions; the only difference are the additional modules you get for paying (firewall, anti-spam, etc.). So "free < paid" doesn't make sense.

And as far as Avira having poor detection... Well I've never, ever heard anyone else say that, particularly


madmike reviewed v5.0.545 on May 10, 2010

Tis very good compared with the other freebie AV programs out there,( the worst from my experience is Avira - paid or free) but having tested this its not the best IMO.

I have tried a lot of them Norton being a calamity trying to run like an OS using lots of resources, Avira - detection rate poor etc.

My point here is the best thing about Avast is its free but for the ultimate protection I found Kaspersky the best, I had Avast installed and removed it installing Kaspersky and immediately it found 4 Trojans Avast failed to spot.

In summary, Good for Free but by no means a replacement for a paid solution.

Absolutely no security product is the "best currently available", any more than any one car is the best. Everyone is different, and every system is different. I tried two or three different versions of Eset Smart Security, and had numerous problems with it every time. Avast!, on the other hand, works very well for me. Version 5.0, specifically, works much more smoothly (for ME) than did 4.x.

Like I said, there is no "One True Solution". Up until recently, I was a big Avira fan, but they blew it with their refusal to do even basic QC on their latest product versions. Just use what works for you, and spare us the evangelism.

Believe it or not, despite the size, this is lighter than MSE both in real time protection and on-demand scanning.

Maybe this is due to the fact that the new engine use multi-core cpu more efficiently, and I'm sold.

I used to recommend this product.

It is now huge, bloated and exacts more overhead than it's worth. I switched to AVG until it met a similar fate. Now I use Microsoft Security Essentials and it's faster, uses significantly less machine resources and offers just as much protection. I've measured the detection against corporate AV products such as Symantec EndPoint Protection to verify the detection capabilities.

In the face of this, I can no longer recommend the product when a faster, leaner, more efficient and equally protective alternate solution is available. The product needs some serious slimming down.

THREE stars.

I am very happy indeed with this program - it updates the virus database via my slow modem line and doesn't hammer my old windows 2000 machine every time you open a file. It found some viruses which had been on the computer for some time before I installed it, and has since detected others trying to sneak onto the system.... so I went pro, which is good value.

Avast is signature based. Which means it has no heuristic scanning in the free version. It has it in e-mail. But what good is that when 9 out of 10 people use web based e-mail? When all you want to do is scan your machine avast will not "look" for certain behaviors. That's because it doesn't use heuristics when scanning files on your computer. Without heuristics your computer could be infected and avast will not detect it.

This is a tough one. first, AV tested the Pro version and not the Home version. In their latest test (Nov.2009), here is the breakdown on detection rate:
Avira- 74%
BitDefender- 53%
Where Avira loses and Avast gains ( along with Microsoft and Bitdefender) is in false positives). What score you give in this area is somewhat subjective but looks what happens when you use AV's approach:
Avast, Microsoft, and Bitdefender all get 3 stars or Advanced+
Avira gets only 2 stars or Advanced
Now lets be serious- does anyone really think that Microsoft and Bitdefender rate an Advanced+?

Re 5.0.70:

This is a very early beta and it doesn't have full functionality yet, it actually doesn't even have full virus definition database.

Limitations and bugs:
This first beta still has some limitations/bugs/problems. To name the most important ones:

1. it currently doesn't contain the most up-to-date defs. That is, part of the defs are somewhat outdated as we're still making changes to the infrastructure. Hence, it is not recommended to use this beta as a tool to protect your system. Also, it is probably too early to do any detection tests at this time.

2. the Behavior Shield is not yet fully connected (has very limited functionality at the moment - is just a skeleton, really)

3. the antirootkit component is not connected

4. there is no licensing component in this version; i.e., no registration, no activation... however, there's a hard-wired time bomb that will disable the program in about 2 months (there will be multiple beta refreshes before that happens, and hopefully even the final product)

5. the sounds are missing. We plan to have sounds in the final product (and later betas) but they're not there now.

6. the design will likely change a little bit still... some of the corners will be rounded etc...

7. some of the Web Shield settings are missing

8. some of the Shield settings actually require the Shield to be restarted to become effective (Actions, Alerts, Report file, Packers, ...)

9. the GUI sometimes doesn't get refreshed automatically (i.e. you change something via the tray icon, and the main dialog doesn't update itself to reflect that change)

10. the iNews, Community and Event log pages are just placeholders atm

11. the Scan Result window still needs some changes

12. the built-in program updater doesn't ask for a reboot when it's done (even if it's necessary in order to apply the new update). Also, the update, when initiated from the main UI, may end up in an unexpected state. As an alternative, we recommend using the updater in Control Panel -> Add/Remove Programs -> avast! Free Antivirus -> Change/Remove -> Update.

13. context-menu scan in Explorer doesn't work.

"The best there is and now also equipped with heuristics"

Do not use Kaspersky, Norton, Nod 32, Bitdefender, AVG etc. use Avast and you will have a pc that is malware free and a program which is reliable and just works. The program has a lot of features which many other lacks, features which are essential in the fight against malware. I have been in contact with the company behind Avast named Alwil and they have informed me that since version 4.8 Avast is equipped with heuristics. They are planning to announce this together with other new features related to heuristics in the third quarter of 2009.

Avast is a protective fortress with all its shields and will protect your pc against viruses, spyware, adware, rootkits and other malware. I have used Avast for nearly four years in different computers and it always work reliably and have kept them free from viruses.

Avast has a lot of cool skins to choose from. It is not a dull anti-virus program like the rest.

It is also free!

Note: Equipped with heuristic means that the program has a capability to catch unknown viruses.

It's a good AV. Although, it will slow your PC (as other reviews below me giving poor criticism on this product) for a short time while avast! updates it's database everyday, it's not resource hog like Symantec and it's less expensive than McAfee. This AV is a bit more accurate against viruses, trojans, adware, spyware and rootkits.


Morningdove reviewed v4.8.1335 on Feb 6, 2009

For the record, the 3 ghastly creations shown above are not the Avast GUI. They are supplementary skins should anyone (ugh!) want to use one of them.

Avast is a fairly decent program, but COMODO did find a couple of nasties Avast was ignoring, and startup is slightly slower with Avast. On the other hand Avast ignored 15 NirSoft false positive files that COMODO identified as viruses. Also, Avast does not interfere with defragging as does COMODO, and the animated tray icon is a nice touch. Avast does put a noticable drag on the system when installing it's AV updates, but only for a few seconds. I notice no delay when using Avast real time scanning and have never personally had an issue installing software.


myboy reviewed v4.8.1296 on Dec 31, 2008

What the heck happened? The program used to be so good -- speedy and stable. Now, they fixed the long boot up times (not really, I just unchecked a bunch of stuff); however, they've added in system freezes for good measure. I kept wondering why my system would seemingly kick the bucket while installing drivers or software. It was avast. Once uninstalled, system stability returned to normal.

Alas, I have to use AVG as a result.


jungle! reviewed v4.8.1296 on Dec 24, 2008

I cannot see why this AV is so popular at all. It scans every file on your system and slows everything down to a snail's pace. Launching browser, text editor, etc, takes forever. Useless to me.


psycros reviewed v4.8.1296 on Dec 2, 2008

(..and thats a HIGH 4, btw. I only reserve a 5 for apps that I believe to be as perfect as the current technology allows.) Avast is missing one feature common to other AVs that I would sorely love to see added: a list of common file types to exclude from scanning. Every single filemask you want the scanner to ignore must be manually entered. Its not simply Avast defaulting to a "scan everything" behavior - there is literally NO list of exclusions except the one that you create. I would also like to have some clarification of just how well Avast handles adware and typical pseudo-virus programs..this really isn't addressed in their advertising, help files or other documentation that I've seen.

The best free virusscanner in the world today is Avast, leaving Avira and AVG behind, one the main reasons is that has a clear interface and it is looking into pakked files. Norton 2006 has pusched a lot of his users away in 2006 cause it was using to much cpu and finally all other virusscanners gotta a chance to prove them selves and showed all of you that there is more then Norton on the horizon to discover, also for me counts : no more mr.Norton!

I have used a PC recently which had Norton installed. I saw little that would persuade me that the protection offered by Norton is significantly better than that provided by Avast. As others have commented, recent Avast releases give very good broad protection against all types of malicious code.

It's absurd to say that 'you get what you pay for' in relation to this product. Avast has no monetary price but is of great of value to its users.

They have now updated this to version 4.8.1290. It installs and runs fine in Vista x64, one of the few AVs to do so. I am using the Pro version.

If you are reasonably careful in Vista and leave UAC enabled, you really don't need an AV at all for your own protection, but since I sometimes receive .doc files by email I like to check them just to make sure nothing bad gets passed along to anyone else. But I see very little CPU usage by avast!, and it uses relatively little memory for an AV (I have 8 GB anyway), so why not?


aszure reviewed v4.8.1287 on Nov 19, 2008

This is my main AV, and has been for a couple of years. If you turn on all the protection, it does bog your system down a bit. But I usually leave it at the middle of the road setting, and it works just fine. However, make sure that you turn the audio notifications off, or you will hear "Your antivirus has been updated" at 5 AM. It kinda freaked me about a bit. Great product tho. And well featured for it being free.

IF there is a performance hit from this product then it is minimal compared to most(all?) others. One of the nice things is that it's so simple to switch any or all 'providers' on or off via the tray menu which actually regains memory.

Increases boot time, increases system load time, slows down programs, slows down opening of windows, makes web browsing really unbearable, slows down even the world spin. Checks everything what opens and moves. I have a suspect that it checks mouse movement too.

Otherwise, good complex solution, has no nag screen and free version is almost the same as commercial version.


irv4oh reviewed v4.8.1229 on Sep 1, 2008

PROS: Impact on system performance is much improved over the earlier version I last tried: I haven't noticed any impact on system performance.* Web Shield does not slow down browsing, nor does Network Shield. Scanning within archives allows for scanning within many types of file containers, such as 7z and MSI. Update check is frequent (by default, 3 hours). Screensaver module is useful and highly customizable; can be combined with similar screensaver utilities such as JkDefrag. Spyware protection is integrated, and Web Shield provides additional protection for downloading. Scanning for rootkits is part of standard scan.

CONS: *I chose to tweak many of the settings: turning off scanning memory during startup, disabling skins, deselecting some Shield modules from install, disabling Standard Shield from scanning applications and DLL's on load, removing update and VRDB notifications, disabling tray icon animation, disabling sound effects, and combining the VRDB and main icons. Seems to not include behavior-based protection, but Avast plays well with Threatfire. Avast has no scheduled scanning (except screensaver module), but Threatfire does.

Bottom Line: After tweaking settings for performance and to reduce annoyances, I'm very pleased with Avast, especially in conjunction with Threatfire.


buggedbyav reviewed v4.8.1229 on Aug 9, 2008

I just signed up only put in my review of Avast 4.8. I downloaded and installed it about month and half ago. I was using AVG 8 but found it slowed my PC (it's a six year old clunker with 500 MB RAM - 20 MB dedicated to video. It runs Windows XP ser. pack 2 - totally up-to-date. All this is within sys. reqs. I Can't afford a new'un right - so this has to do.) Anyway AVG slowed the machine down something awful. So I heard "Avast is great! Try it you'll like it!"

Well like the old Alka-Seltzer commercial said: "So, I tried it. I didn't like it".

The main problem is that Avast, unlike AVG, scans everything that runs - every time it runs. Many times I had to disable the scanning feature just to get my major apps (word processing, database and browser - FireFox 3.0) to start in a reasonable amount of time.

Yes, I tried to fiddle with its configs. There is a place to disable this continuous scanning feature in the config GUI, but it never seemed to work. Usually, I was forced it to stop from the tray icon.

That scanning feature in Avast on this old clunker made AVG look the rabbit from the old fable.

I will say Avast installed seamlessly - but installation is not use. Protection I need but not at the expense of all the resources Avast uses.

Maybe when I can afford to upgrade to a dual-core with 4 GB RAM I'll try again, but for now I'm headin' back to AVG - better to be slooooow than totally stopped. Besides, I've used AVG's previous iterations and know what to expect from Grisoft.

Not only detection rate counts?
That is exactly right if you are a brain washed fanboy,or you just want to be able to say you have "a" anti-virus on your machine.
My queston is why have all of these "shields" and "guards" if they are unable to DETECT what they are spposed to "shield" and "Guard" you from?

Detection is not the only factor that is true.
System Impact is important.
what good is a clean computer if your anti-virus slows it down and degrades performance worse than most malware would?

Avast has the detection of a blind dude in boxing gloves looking for a needle in a heystack.
It slows surfing,eats memory,delays boot time time,its interface is designed to trip you out,the instructions are un-clear.

One thing it does well is update.
Although with this clunker it really does not matter.
I know,I know,people are going to say:"I love avast! I have had it for five years and never had a virus!"
if that is true,they can just uninstal Avast and save some CPU and memmory.
It has not been Avast that has has kept them safe,it is either clean living or blind luck!

Yes,the Avast guys are serious.Maybe they should even lighten up a little,something needs to change,their product is crap.
but most serous of all is the legion of fanboys that forget we are talking about a bunch of "ones" and "zeros",not their family,religion,or country.
That level of blind loyality to a piece of software is scary.

"2" rather than "1" because it is 'a" anti-virus,just not a good one,and its free.


DudeBoyz reviewed v4.8.1201 on Jun 26, 2008

A solid 4 for now - if 4.5 was an option, I'd give it that. But I just don't think it deserves a full 5 yet.

Detection rate may not be as high as AntiVir, but like AVG, it does scan your email, which is to me at least, an important feature.

The fact that you have to get a yearly registration code is a minor annoyance, in part because AVG does not require you to do so, however, since AVG 8 has turned into such a bloated pig of a program (when compared to AVG 7.5), I think I can overlook that issue.

The simplified interface is sort of annoying too. I wish I did not have to pay to get a more grown-up looking interface. I do wish that by default, I could select NO SKIN and have it simply use the standard interface elements that are in the current theme.

Also, the dialog that pops up when a suspicious file is found is not resizeable, so I cannot see the actual path AND file name it is flagging. If I click the MOVE/RENAME button, it turns out I can resize THAT one so I can stretch it wider and so that I can see the path and file name, but that inconsistency is a pain and one extra step that I am required to take but should not HAVE to take, you know?

So, not perfect and sorta slow to scan, but pretty darn good overall.


bokhylla reviewed v4.8.1201 on Jun 3, 2008

Not only the detection rate counts!

According to AV- Comparatives Avast earned a advanced plus on demand detection of virus and malware in February 2008. That is a fine reward.

But I do not think that this is the main rational argument for considering Avast. Some other anti-virus software scores in this regard even somewhat better.

The main arguments for using Avast, apart of being free, is all its special features. What comparatives and Virus Bulletin does not consider are just those features and they are not either supposed to consider them. They consider mainly only two things and those are the detection rates and that the software does not make so called false positives. Those considerations are extremely important but, please, do not consider them as the whole truth but only a very important part of the whole truth.

Also consider those very important features Avast has such as resident protection, P2P shields, web shield, boot time scan, virus chest (which protects in a vault, against malicious attacks, certain files which are very important for the operating system), network shield (a lightweight firewall) and other features.

In other words, no good having a good detection rate if the software does not also have a good capability of detecting malware and not just in the laboratory, but also in the real practical world.

Alwil is the company which makes Avast and Alwil is indeed a very serious company. It does not nag you with all sorts of ads asking you to buy, buy and buy. This makes a difference and actually tells you something. It tells you that they are serious. They make a software which is considered to protect you in the real world. They have seriously considered all those features when they made Avast.

Apart of all this it is, as mentioned, a free software which also protects you from spyware and rootkits. It has a lot of skins to choose from which makes it in fact really special and attractive. Those properties are also very important.

No AV deserves a Gold rating due to the simple fact, it is not possible to detect every virus out there. I've used most of the AVs available, free and paid. I switched from AVG Free to Avast Free because of various conflicts that AVG was having with Google and other software on my PC.

I have yet to find any issues with Avast. I am trying to figure out why some people seem to think Avast is a resource hog, right now on my system it is using just over 8k of RAM total. Now if I was running a 386 with 8mb of RAM I would be worried, I not. AVG used about 15k to 20k, McAffe was in the 30k to 50k, Norton is the worst coming in at almost 100k.

I've been using Avast! for a couple of years. Each version offers more comprehensive protection without the increasing bloat that accompanies other anti-virus products. The addition of rootkit protection in the 4.8 series is excellent.

A couple of weeks ago my computer began hanging every time I booted up and finally I had to take it to my local PV repair shop. The techs there are excellent and have done very good work for me in the past.

Anyway, when I went back to pick up the PC, the tech told me that my problem had been caused by my Norton Antivirus, which has essentially "broken" the machine.

They fixed it by completely removing all traces of Norton, and installing Avast instead, which they told me was their preference. It's been working great so far, has already saved me from an online attack and I upgraded to this new version this morning.

I rarely write reviews, but I have to say this is a very reliable antivirus program. And the price is right too. ;)

What the hell are you talking about, it's Avira, that doesn't have email protection in the free version. Avast had email protection from the beginning. Also, Win95 look? You didn't even see it, right?

I have read your post:

Does this home edition ad an option to scan in/out goiing pop3 now? I know they didn't some time ago and you had to purchase to the professional edition.
That is why I choose Avira Personal Classic Edition...

As I wrote, Avast HOME always had POP3 protection, you didn't have to buy the Pro version to get it, so the part about choosing Avira because of this doesn't give any sense, especially when considering that Avira DOES NOT HAVE POP3 protection in the free version.


radiomaffia reviewed v4.7.1098 on Dec 5, 2007

Does this home edition ad an option to scan in/out goiing pop3 now? I know they didn't some time ago and you had to purchase to the professional edition.
That is why I choose Avira Personal Classic Edition (free also) and must say it Avira works almost as good as Kaspersky and the free edition from Kaspersky through AOL isn't available anymore.
Also, Avast should take a look to that unprofessional design, that is so out of date and makes me think of W95 and earlier.

Does the job, but it's anything but fast. If you have a directory full of a LOT of .exe files, such as a downloads/incoming directory, and you navigate to that in Explorer you can see just how much Avast slows that simple operation down. It's good software, and does its job, but it is most definitely SLOW. And I'm sorry to tell you, but any and all versions of NAV are much faster, not to mention have a more complete definitions database. Call it bloat all you like. It's still faster than Avast. But, Avast is free.

I found Avast! after Norton 2006 annoyed me once too often. Norton slows everything to a crawl and I had to reinstall it three times in as many months due to problems updating the virus updates. Avast! is like a breath of fresh air - no nagging pop-ups the size of the US cluttering your screen, no noticeable slowing down of your computer and so far it seems on the ball when scanning/detecting viruses. Its being free is a bonus rather than a criterion for an important area such as virus protection, but why pay good money when you don't have to? Strongly recommended.

Very good antivirus program. Unfortunately, the Avast e-mail virus scanner is a piece of crap. Every time it finds a possible indication of a virus it stops downloading e-mail and pops up a message requiring user input effectively preventing you from setting up your e-mail client to download e-mail unattended. Symantec's Norton Antivirus 2007 product doesn't do this.

Also, even though Avast has excellent virus detection rates, it has very slow virus scanning performance and does a poor job repairing already infected files compared to Symantec Norton Antivirus 2007.

I would not say that avast! was among the "top 3, free or otherwise". Top 10, though, yes.

I cannot comment on how good Avast is at removing malware infections because I run Avast's real-time scanner, so it catches and quarantines the malware before it has a chance to install itself.

TGB72 reviewed v4.7.892 on Dec 2, 2006

Avast is a very good free antivirus: probably the heuristic is not the best but definitively is there and avast not depends only of his database to detect crap. Otherwise the virus database is updated almost every day. About the slowdown is relative, if you've a 1Ghz/512MB PC or better probably you won't see any slowdown, you could see it if you run it in very old pcs.
Last but not least keep in mind that the fact that you keep clean your system is a 50/50, the 50% that belong to the system itself is over the shoulders of your firewall (by hard & soft), antivirus and anti-spyware, the other 50% depends on you and your habits on internet, email, soft installation and pc maintenance & configuration.
You've more probabilities to get some virus/trojan/malware if:

* You don't use a good firewall well setted (first block all, then allow only what is necesary it's a good idea)
* You use crapy browsers like IE and to navigate through "insecure places" catching all class of crap.
* You don't update your antivirus & anti-spyware often
* You don't update your system with the latest SP & patches
* You don't filter your mail
* You've running unnecessary services
* You accustom to install unnecessary soft just for curiosity

If you don't take care of your system doing your 50% there is no way that Saint Kaspersky or Saint NOD32 do it for you.
Otherwise don't pay attention to not objective/unfairly/bad intentioned reviews. Like I said Avast is a great antivirus and probably the best free one.

Avast is a slow antivirus, resource hog, get away from it!!!

Slow scanning speed, slows down computer performance, slow response to the new threats.

Avast has no outstanding detection technologies but Avast is so slower and uses more and more resource than top antivirus such as Kaspersky, NOD32, Antivir, why?. Avast has no heuristics, it simply relies on its virus database which so slow for adding new threats, so what you can expect from Avast.

I hope Avast developers should focus on improving Avast's detection capabilities and reduce resource consuming rather than adding useless features.

If you want high quality free antivirus, Get Active Virus Shield (powered by Kaspersky engine), AntiVir or AVG instead of Avast if you want to be well protected.

BTW to the post below "don't be scared away by the AOL tag". Pfft. Here is a quote from the Terms. I like my AV spyware free personally....

"1. Information Collection... consists of personally identifiable

If it's not the very best, it's way up there. The P2P protection has saved me from countless viruses.

The only really irritating thing for me is that when it automatically checks downloads it seizes the cpu, the computer is essentially frozen while it's running the check. Never found a way to change the task priority for that.

Free, thats about it. In the AV world, you get what you pay for. This AV will detect about 10% less viruses than the best paid AVs. 10% is a huge number given the fact that there are hundreds of thousands of viruses in the wild. Out of 300,000 viruses, it will miss 30,000 viruses.

Check it out for yourself.

Also, AOL is offering a FREE AV that is built with the Kaspersky antivirus engine. THAT is the best free AV. Dont be scared away by the AOL tag.

Auto-updater now run with normal priority (used to be high priority) - nice! I love avast, but it was annoying how my PC (I only have 256MB RAM) would slow right down for minutes with no explaination - ending in the explaination 'virus database has been updated' - weird though, as if I updated manually it only took seconds. Avast just keeps getting better!


Banquo reviewed v4.7.869 on Aug 7, 2006

I agree the skins are ugly, so I don't use them. I wouldn't use them anyway because an antivirus program having skins is almost as ridiculous as giving it a lower rating because of how they look. They're optional, so they should not count in the rating. Getting back to Avast this is the best free antivirus utility I have found. I used to use AVG until I found out that it misses tons of stuff.

Agreed with alexweber15. Silly and useless skins. Fortunately there is an option to use default standard interface. Avast team: please remove them and as you don't need to maintain this useless feature, may be you can lower the price to make the product even more attarctive. If I had to choose between two equivalent products (same price, same performance), I'll go with the one having no skin. May be it's not rational but the skins give the impression of kid toys and amateurism for this kind of product.


Viajante reviewed v4.7.827 on May 25, 2006

Yes it´s pretty and yes it´s really good, is fast, doens´t eat many ressources and has a lot of features that other free products doesn´t have like POP3 scan.

maybe this has gotten better recently but according to and many other sites its just not as good as AntiVir for example. also, why the bloated interface??? if the program does its job you should barely need to open the interface and there is no need for silly stuff like skins.

Extremely good antivirus. I'm another one who has converted many home users to this program. It's fast (greased lightning compared with Norton), and I too have often had it find viruses already present on a supposedly clean system (again, even moving from Norton).


burfadel reviewed v4.7.817 on Apr 20, 2006

This is an excellent antivirus programme, I don't know how people could knock its effectiveness unless they're form a competing company! The only complaint I have is the interface, but few people actually use interfaces these days and rely on the resident shields, and Avast! has one of the best resident shields around. This is from both personal experience, and as well of course with the acclaimations that they have received with their success rates.

Much better that AVG, or Antivir for free use (unless you find the interface confusing if you use it)! lol

AND ITS FAST, the resident scanner is fast and does not compromise on catching the viruses out!


bbplayer reviewed v4.7.817 on Apr 20, 2006

One of the, if not THE slowest virus scanners on the market. Very limited protection (as expected from something that is free). Also, not a huge fan of the bloated interface trying so hard to be winamp, but falling so short.

AntiVIR would be the better solution for those who dont feel the need to pay for anti-virus software.

Use this software if you dont value your data, because you WILL get hit... just a matter of time.

Great AV program. One of only two that I would be willing to pay money for, but since it's free I don't have to. The other good one is Computer Associates eTrust. They're both awesome, I choose this one cause it's free.

AVG is not better than this, I have switched numerous AVG users to this, and it found lots of stuff on their systems that AVG couldn't catch. Same thing goes for Norton and McAfee.


eclipsingdivinity reviewed v4.7.817 on Apr 19, 2006

Always enjoyed Avast, It's got a variety of features though some of them I hardly understood. What's the point of having all those scanners, when one resident scanner could do most of the job? Well at least it gives me a warm fuzzy feeling knowing that it can cover a broad range of security breaches, such as a small network intrusion prevention guard which detects attempts to access your PC, and a web scanner which scans your browser cache for exploits through your browser. Automatic updates are done very well and incremented to the point where you don't notice them installing.

Though I dislike the default interface, and I would dock a point for that, but you can turn it off and use the simple interface it comes with, or just use a decent skin. I would also like to complain about its resource usage, but that's been chopped quite a bit since 4.6. So with Avast running leaner than before, yet it keeps the same features you enjoy and for the price...It's a perfect 5 in my book which is hard to accomplish. Sure, it doesn't have out of this world detection rates, but then again the biggest virus stopper is yourself, and Avast makes a great buffer if you should ever make a mistake.

If they ever get around to fixing the GUI, i'd give it a 10 out of 5 :-D

nefarious1 reviewed v4.6.763 on Mar 14, 2006

avast! is a good anti-virus solution, but the inclusion of skins support, even if they can be disabled, is a joke.

Main reason I give a 3 is because avast! freezes on my system, for stupid reasons such as update attempt timeouts.

There is also no way to have the HTTP scanner check archives. So if malware is in so much as a one-layer ZIP archive, it'll let you download it. If the same file is an EXE, it will catch it. That this isn't even an option is lame.

You also can't exclude applications from the HTTP scanner.

experienced in both current avast! and norton builds and avast! can compete with the big dog. if you're looking for a good AV program, avast! is in every way as good as norton av, only it's free.

free download + free updates = win

the virus DB is updated at least once a week, but usually more. the program itself is under active development. it was among the 1st x64-compatible AVs on the net, months ahead of Norton, and is probably lighter on resources as well.

having used avast! for over 2 years and with extensive Norton AV experience, avast! deserves a look. it is my Av of choice over norton, and if you have a current norton subscription, avast! would be perfect for when it runs out. i install it on every PC i maintain, service, and tweak, and it's definitely a 'set and forget' application.

benZin: "It's NOT a Anti-Virus."

The only antivirus I've used that can give Avast a run for it's money (not sure if that saying even works since Avast is free) is Computer Associates ezAntivirus. But I switched to this cause it's every bit as a good, and I don't have to pay a yearly subscription fee. I have saved dozens of friend's computers by removing McAfee and Norton from their systems and installing this.

For those of you having problems with it, did you ever stop to think that your system is the problem and not the software. I am a computer tech and keep my system very clean of fluff and have very few processes running on startup. For those of you that have 40+ processes running on startup, you are going to have problems with just about anything, especially if you don't have much RAM.

This is the best FREE antivirus app on the 'net.

It has the best resident scanner I have EVER seen. It's resident/real-time scanner is INCREDIBLY light on resources, even on one of my 233 mhz notebooks, never goes above 2%.

It runs a fairy large array of services; update, emailscan, p2p scan. I turn off the auto update since it actually tends to hog resources for the short time it runs, so I cancel it by running services.msc.

The gui is a bit bloated, but can be easily fixed by turning off the skins.

Has a very large virus database, and updates are very fast.

Norton Antivirus is crap, it costs too much, has a very small imunization database, and is bloatware. None of these apply to avast!

The updates, much needed. Tends to start up faster now.

I've been using avast for about a year and I can confidently recommend it and recognize it as the best free AV out there. It's just made things so convenient and simple, the way it should be, and it does the job reliably. Here's what I love about avast:

1) Very light on resources- this is VERY important to me.. no bloatware

2) Automatic updating

3) Frequent definitions

4) Superb support forum; dedicated team behind the program

All in all, it's just extremely convenient for the user. It sits in my tray, automatically keeps itself up-to-date, and keeps my system safe for free. It might not be the most powerful or fast AV out there, but bottom-line: if you're an average user looking for a free, no-hassle antivirus, this is the program for you.

After my McAfee expired on my main computer I was a bit juttery about moving over to AVG which I've got on the rest of my computers. Yes it does work, but the interface is a bit clunky, and I know others who've had problems with it. So after a long hunt I thought I'd give avast! a go. And I'm so happy I did. This is definatly the best scanner I've used. So much functionality in a free version. its amazing. And all the tests seem to rate this slightly above AVG for what it finds. I'm not going back I tell you! Also the skins can be turned off so it doesn't look silly/take resources which was something putting me off from the screen shots.

This is the ONLY virus scanner currently available for the Windows 64-bit XP OS that i am running. It was easy to install and run, time will tell if it works well in the 64-bit environment.


dangermaus reviewed v4.6.665 on May 23, 2005

I have been using this for months. It updates automatically and runs in the background. On par with many, many other AV programs. Besides, you don't need to crack it, it's free for home use!

really great anti-virus program in par to AVG 7.

Nikkita reviewed v4.6.652 on Apr 22, 2005

One of the best antivirus software around. It seems to be quite reliable with its regular automatic online updates of virus definitions (sometimes twice a day). I switched to Avast from Norton which took more of my computer resources than this program. Avast has very unusual but convenient interface. I have checked this app with several testing tools and it has passed all the exams. I have already been using Avast during several months and the only negative remark I can make is that scanning of my HDD (20 GB on one partition) takes quite time.

I've heard good things about both AVG and avast!. About a month ago, AVG caught something... and I don't mean it found it, I mean it CAUGHT it. So did my shell32.dll. I'm scanning with avast! right now and it's already picked up a few small things that AVG didn't. Plus, this has many more features. Beats the snot out of Norton, too. I think I've found my new antiviral solution!

I’ve been using Avast free edition AV since December when I found out that Symantec had jacked up the one year subscription renewal price for Antivirus 2004 to $40.00.

Avast seems to use less resources than Antivirus while providing protection for email, IM, and P2P in addition to regular anti virus protection and is a much better product. I can never see myself using another Symantec product again, Avast is all any home user should ever need.

OK, I am using Avast! for about 1,5 years now and I didn't have any problems with it. But WHY do I like this piece of software. Ok here goes


- Avast! Home is 100% free, can obtain the licence key for FREE and the only thing you have to do is copy/paste it into the programs "licence box" and you are up and running for a year!

- Avast features everything you need in an AV system. It supports more chatclients then NAV2005 and supports P2P downloadprograms.

- Avast has the best support there is! An online webforum where users can test the newest BETA versions before it get released! (at the time I wrote this, version 4.6 is heavily tested by forumusers!) Questions/remarks/problems can be answered online!

- Avast is a multi-language program!

- Avast updates frequently fully automatic!

- Avast! has a Screensaver-Anti-Virus Scanner!!! (my favorite feature)

- Avast is ready for the 64-bit platforms!

Avast is not that XP-styled like panda antivirus or McAfee, it might not be that goodlookin like some like!

If you can live with my only con! Yes sir, Avast! is the AV underdog!!

I read the reviews and although I had NOD32, I installed avast! Home as well. Well, just at the end of the installation it locked my XP PC. I couldn't even end task, I had to shut power off.
I booted again and it worked fine until 3 days later when automatic virus definition update was performed as per the popup message. It locked my PC again. Nothing would work. Shut PC off again and back on. I wanted to uninstall, it wouldn't do that either. Shut PC off and then I successfully uninstalled. I wouldn't dare install avast! again. I don't think it had anything to do with the fact that I had NOD32 installed because under avast! Pro, reviewer Dwarden on Sep 12, 2003 with Version 4.1.259 says "Excelent Antivirus, with NOD32 this is TOP product ...!" I really wonder !

It is only a 58 day demo if you don't register. They require you to register every 14 months, but home edition is free. So far I have received no spam from registering.
I have installed avast, avg, norton, and mcafee on client computers. So far, avast seems to offer the greatest protection against viruses. I have noticed a slight performance hit on WAN networks, compared to avg, but not nearly so bad as norton.
I highly recommend


tom3311 reviewed v4.5.561 on Jan 9, 2005

Avast works...but this is NOT "freeware" but a 58-day demo. On the performance... It does not hold a candle to AVG v7 Free, which has a more logical interface, daily updates of its virus database, and works. I think the Avast interface is trying to be too cool...antivirus software doesn't need to look "skinned" just needs to do the job in the background. Plus it bugs me, BIG TIME, when a company offers something as "freeware" when it's really a limited demo version, whether that be time or functional limitations.

I use Norton Corporate at work, Norton & Avast at home. Avast is what I recommend to folks who let their Norton subscriptions lapse and come to me with broken pcs. If I rebuild, they get an image of their drive, a lecture from me about the hazards of the Internet, and lastly, a pointer to the Avast download site if they can't promise me they'll keep paying that Norton update fee. Rates close to a "5" in my book.

I dont want to appear excessive, but to me, avast is certainly the worst antivirus i have ever tried. Unprofessional, unintuitive, clumsy, bloated with fancy graphics and useless functions. and it sucks up tons of memory (like all antiviruses, but here it is far too much).

the fancy skins (ugly) and "what a flash" namings for the software functions, are just the proof that this is developped to impress visually rather than functionnaly. It didnt stay long enough on my machine for me to appreciate its efficiency. rating: -1

Very good freeware antivirus program. I believe the resource usage has actually decreased in the new versions (less memory, does anybody agree?).

It asks for a license key which you get for free when you register with a valid email.

Oh, and best call ever by the developers: They finally provide an unskinned version so you don't necessarily need a skin. This is good, because the skin tended to disappear before and the main program would refuse to start then!

I did a quickie eval on paper of the freeware AV products out there. That left me with two, Avast! and AVG. I then proceeded to test those at work in a sandboxed virus-infested environment (I'm in IT Security). Both acquitted themselves well well but Avast! has a more extensive feature set, offering greater protection overall. The icing on the cake was the excellent support (AVG support is non-existant for their freeware product) and the excellent user community. Add to that regular updates of both code and definitions and you have a winner.

I am slowly (with each successive rebuild) replacing all the invasive Symantec stuff on my home network with the lightweight and efficient Avast! 4 Home (there are six machines).

This is one of the best "free for use at home" antivirus programs. Timely pattern updates, unlike some of the big names who should know better. This version does away with the need to configure your email program (Outlook Express/ Thunderbird / Edora / Pegasus Mail) and in so doing might break existing setups which might suddenly find they can't send or receive mails. The solution is to reconfigure them to talk direct to your ISP's POP and SMTP severs (Avast now intercepts this and scans transparently)

CyberInferno reviewed v4.1.389 on Apr 23, 2004

Great antivirus program for the price. It updates just as frequently as the large corporations and is good at automatically grabbing definition updates. That was my biggest complaint with AVG. Even after modifying the url.ini, it still failed to update a lot of the time, which meant scheduling daily updates was worthless. Avast not only is good about automatically updating, but if I want to manually check it requires two clicks. My only complaint with Avast is its interface and inability to schedule automatic scans. The interface is too cutesy as some others have said. However, it has a low overhead, it's a very good scanner, and you can't beat the price!

uxtheme.dll only works for windows xp pre-sp1, if you have sp1 or older you can't use that trick, but stylexp has a feature to not use system resources, which is the same as the uxtheme.dll trick

I used to use this program, but now i use the UXTHEME.DLL patch, does the exact same thing for free. Style XP may be better for some novice users who dont know how to replace files or move files into the theme directory however. And as for this new version's ability to change boot screens and logon screens, there are plenty of free programs out there that do the exact same thing.

Ok for email. it's free = good! but missed some common virii on infected pc, KAV detected. Realised paying for KAV once again is worth it.

With version 4.0 avast really seems to have become one of the best scanners out there. 4.1 adds great new features such as IM-scanning! At there might the failed/ok ration might be misleading, have a look at the details and you see the latest test almost completly succided. I never did have any problems with avast and only can recommend it. It detected the eicar virus witout problems, as file and also as attachment. Maybe some guys here should check their email programs configuration, avast isn't able to autoconfigure every mail client! My manually configured TheBat works great, so does autoconfigured Outlook and Outlook Express.

Excelent Antivirus, with NOD32 this is TOP product ...

The best antivirus I have tried Norton, NOD32, Karpesky...). Great program, beautyful interface, doesn't need many resources, great support! Highly recommneded!

All versions of avast! antivirus known to me undoubtedly can identify the Eicar test file (everyone can make sure of this himself - the source can be found, for example, at Moreover, in the latest Virus Bulletin tests (June 2003, Windows XP) avast! from Alwil Software detected all "In the Wild" viruses during both on-demand and on-access scanning and was given VB100% award (

Avast! is a good anti-virus program, especially for free. AVG doesn't provide heuristic scanning and rarely updates and GAV wants money for real-time protection. So, that leaves Avast! as the only good choice for truly free, good virus protection.


RedBadger reviewed v4.0.528 on Apr 22, 2003

I've tried to like this program, but every time I've ended up uninstalling it. Last time it failed to recognize the eicar "test" virus that all scanners use to assure you that the resident scanner is active. I uninstalled it, then tried this program again a couple weeks later, only to discover this thing doesn't even scan email attachments. (despite the fact you tell it your email server names during setup) You have to actually execute the file before it will scan/detect them. So you can send all the viruses out you want in email file attachments, and it won't detect them. It also does not scan files as you download them, or after they are downloaded, it will only scan it when you execute the program. If you don't believe me, try the website to download the test file all scanners use.

This program may look good, and seem to be working (in theory), but I can assure you, this software does not detect viruses (that includes the manual scan feature), which a very out of date version of Norton had no problems detecting (and repairing). Don’t waste your time with it. If you can’t afford a better anti-virus (like Norton AntiVirus) then use the AVG Free Edition. It might not look good, but it does actually work.

This is a great proggy, but betanews has the wrong version listed... they just released 4.0.183, but beta lists the last version with a higher version no!


virtorio reviewed v4.0.519 on Feb 15, 2003

This is some good anti-virus. Must better than overrated trash like Norton and McAfee.


jungle! reviewed v4.0.519 on Feb 12, 2003

I totally agree with Yeechie (below);
I had no other apps active in my XP Pro with SP1, ran the installer, selected the option to not schedule the boot scan at load time. And what did it do? Exactly the same thing as it has done to the other reviewer; froze my machine, and I had to uninstall this garbage in safe mode - PLUS many registry keys all over the place. A big waste of time!


wwk reviewed v4.0.519 on Jan 17, 2003

I am running Windows XP Pro with SP1 and all patches. And I don't have any problems with avast! Home.


Yeechie reviewed v4.0.148 on Jan 5, 2003

Ok ghostman, thanks for that tip :)


GhostMan reviewed v4.0.144 on Jan 5, 2003

Some people think it locks up their computer after install. It is doing a scan of your computer and for some reason it doesn't say anything. Just don't click yes to the boot-time scan after install and you won't have to deal with this.


Mr_Puddles reviewed v4.0.144 on Jan 4, 2003

Version 4 looks like a complete re-work of the scanner. It works and is a little more user-friendly. Don't forget to register for unlimited use here:

I cant even get it working.
I am running Windows XP Pro with SP1 and all patches.
After installation of this avast! Home! software I couldn't get my system booted normally.
When its almost done loading with the startup programs the system freezes except your mouse.

I uninstalled this piece of s*** in windows safe mode.


MrPuddles reviewed v3.0 Build 499 on Oct 14, 2002

Works just a good (if not better) than Norton AntiVirus. Has real-time scanning for Eudora, Outlook, Outlook Express, and other email clients. Updates are frequent and are smaller downloads than AVG. This proggy has a better track record than AVG (VBulletin). If you can't afford Kaspersky Anti-Virus (the best IMHO), this is the way to go.
