Avast Free Antivirus problems

One of the best free antivirus software to download is undoubtedly Avast Free Antivirus. It’s the go-to program for most who are looking for a fix quick, but does it actually cause more problems then help with its constant need for updating and notification popups?

Avast works like most other free antivirus software, working constantly in the background and informing you whether something dubious turns up on your computer during a browsing session.

Sometimes though, Avast can run into problems, especially due to registration or update issues whenever a new version is released. Combine this with the frequent pop-ups and you may wish that you had installed another piece of software.

    I have had over a dozen PCs [running Windows 7 Professional (32 & 64bit) running on corporate domains and as Windows Workgroup users] which hang freeze at startup in the past week.

    Uninstalling and re-installing Avast Free (or AVG) does not solve the problem.

    Installing Avast using the offline installer makes no difference.

    Windows 7 appears to attempt to connect to the internet as soon as the PC logs on (standard procedure for Avast update)
    Within a few seconds all activity freezes and only recourse is a hard resetrestart.

    If one is able (by hook or by crook to get Into Windows, the system then hangs during ‘Shutting Down’ and a hard reset is required!

    Starting up in Safe Mode and unistalling Avast using Avastclear solves the problem immediately.

    I have been a loyal Avast user for over a decade!
    This is both disconcerting and heartbreaking!

    Is anyone else experiencing these problems, or know of a fix please?

    Thanks!
    Ken

    I rebooted after an update requiring one loaded, and now none of my applications can connect to the internet. They all try to work but they all just time out. My internet seems to be working fine. No issues that I can see. Even Avast itself works fine, but as soon as it tries to connect to the internet, it just keeps trying until it times out.

    I’ve been using you for more than 10 years always been happy sure there have been some problems but nothing that could not be overcome problems are to be expected it’s like right now my core shields are not working but other than that I’m not complaining

    The latest update (January 2019) caused issues on both mine and my room-mate’s PCs running 8.1… We got the “UI Failed to Load”, tried the repair option… still not working… It actually launched its own “Emergency Update” exe- which caused massive RAM and disk usage… so, we had to uninstall it… Sad, because I’ve been using it for many years.

    It ran ok with W7 and 8 but W10 is a no go.
    I could not download after 2 hours, then found it had downloaded incompletely.
    Found avastantivirusclear,,,,,,,,, it did not function, now I have W10 without any antivirus because message says can’t run with another antivirus installed.

    WHAT A BLOODY SHAMBLES AVAST? AVOID LIKE THE PLAGUE.

    Run as fast as you can from this product. and don’t download ccleaner any more either as they own it and have hidden downloads now. it’s crap, messes with internet access, has endless adverts to try and get you to upgrade, is almost impossible to uninstall and is not proven to be any better than windows built in defender antivirus. Just highly invasive so stay clear, you’ve been warned.

    Latest Avast update downloaded and installed OK. Asked for a “reboot”. Did a reboot and then checked if there were anymore updates, at this point I was told a “reboot” was necessary, did another reboot and same thing occurred. Am now on 5th reboot ! Will now to run a scan and see what now happens. Have 5 other computers to update, am hoping this glitch is confined to only 1 machine ! Am also hoping that this is not a repeat of the CCleaner recent problems !

    Check the BBB piles of unhappy Avast users with valid complaints that have been unanswered.

    I have uninstalled Avast after using it for 13 or more years I tested it this morning on an infected drive it found 0 infections and I know it had 18 or more . I will no longer use this , scheduling boot scans has gotten harder and Avast has become more like Norton every update. More useless features less friendly to use and the worst part it no longer works as an antivirus program. As of today I will be removing it from 35 or more computers and no longer reccomending it.

    I’m definitely not very happy right now and I won’t update for quite a while and if it doesn’t work I just won’t use Avast anymore

  • Jerry Axtell

    After three hours of trying to figure out why I could not access any web pages except Gmail, I uninstalled Avast and this fixed the problem. Worked great for two years prior. Now debating whether to reinstall.

    Desktop at work and Laptop at home having problems after downloading update for Mozilla Firefox 52.2.0 (ESR) through Avast. Desktop in slow mo and so is laptop. Why?

  • Tagg

    Since March have had to take the webshield down, otherwise you cannot access web pages. Avast blamed it on Windows updates not being done, but that didn’t cure it. They say there is nothing wrong. Now today(May 30) unless Avast is turned off completely the pc crashes. !!

    The update on 2 Feb 2017 on Windows Vista 32 bit prevents any other programs from running. Pity, as up to now I had been very impressed with the software. Have had to uninstall and use an alternative. I know Vista only has a couple of months left, but I’d hoped I could continue using Avast until then.
