    Had a problem installing this on my windows 10 system, even after granting it elevated firewall permission, the avast service froze, and the avast repair module was useless.

    I can find no fault with Avast. I am running Win10 and it has performed perfectly. The logo in the tray flashes when it is scanning, checks Email scans at boot, web pages, I like it better than the stock Win Defender.

    This is the top rated free AV according to PC Magazine.
    Correction:
    The actual version of this newly released program today is 12.1.2276 not 72 as it is mentioned here.

    Hi guys - newbe here. I have been using Avast 4.8 professional for yonks 4.8.1335 expiry 2018 and have found it el-stupendo. What's not documented about THIS edition is that when you run Malwarebytes manually, it handshakes with avast and they BOTH examine the files. Whats annoying lately is that although this is a legal registered and paid for edition, I have been getting these daily pop ups from Avast telling me my "free edition is about to run out so register now'. Firstly, I don't have a 'free' edition and it IS registered, I confirmed this by re-registering it and Avast sez 'OK' carry on. The a day later [ almost exactly] this stupid pop up appears again!!. It has not effected my upgrades nor any functionality at all but it is getting to be a pain having to just close the pop up and ignore it. What in the sam hill is causing this to happen AND regularly by time clock every 24 hours, no sooner or later.
    PS. my system clock and date is correct

    I downloaded the last version (1 week ago) I hadn't registered yet, what happen when 30 days expire. Does it still protect my PC?

    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.
