I was using Avast when it was one of the best antivirus available in the market. I abondoned it when it become down because of its impact on system performance. As far as I am concerned Comodo Windows 8 Antivirus seems to be the best one for my Windows PC.

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 so I gave up after a couple of hours. 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. MSE is good for people that don't want to be involved in what is quarantined but I like to be involved in the decision and I think MSE removes the questionable item without asking you.

very good stuff, CyberDoc999 I use to use Avira but I think they went down hill, and switch to Avast free, But as far as I'm concerned the best one out on the market today is M.S.E http://www.microsoft.com/security_essentials/

This thing is Fast & Light on Resources! I have an Atom CPU & this is barely noticeable. I run games such as Halo & Left4Dead2 with no problems. I installed Malwarebytes before this as I was going to run without an antivirus software due to the fear of bottle necking my CPU. Malwarebytes was CPU Intense and noticable slowed my system! Avast has a good detection rate of spyware. People misuse the term Malware. Viruses, Spyware, Trojans & Rootkits are now Generalized as MALWARE. The detection rate & resource usage of this make it a top choice. A/V Comparatives thought so! I agree.

Since version 5 Avast officially also uses heuristic technology (behavioral shield)!

Well I have been using Avast for nearly five years and it is the best.

It has a lot of features and a good detection rate and is the only antivirus that I really trust. Install Avast and your PC will be like a safe.

Get The latest Pro. Release Ver.# 4.8.1351 of Aug. 20\09 at Avast.com This one is out-of-date.. If you use the Home (Free) Version Get #4.8.1351 also of August 20 2009 and avoid the 5.0 Home Beta as it needs development. This is the only Version FileForum lists, so also download from Avast.com

I download alot and get many weird Emails; I have used both Avast Free & Pro. They have always guarded my machines for 5 years without problems.

"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.

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

Without a doubt and by far the best av-tool, and i tried all the others too ! I give ****** !!!

Better than Norton. However, for the extremely lazy Warcrafters who don't have the brain power to run a scan, I still have yet to find you the perfect Anti Virus that will scan and breathe for you automatically. If Avast programmers could get it to update, restart and scan automatically when screen saver goes on, it may sell more copies. Another batch setting would be for it to update and restart the PC in boot scan and after the scan completes, either shut down or boot to Stand By or Hibernate. :)

This was my favorite antivirus program, but for some reason the latest version keeps asking me to restart every time it updates the virus definitions.

Great program, reliable and all the features that a good AV needs

I sorta wish the script blocking extended into other browsers, I haven't had a problem with it but Firefox support and other browsers that use IE like Maxthon and Avant support would be nice.
