For clean uninstallation of Avast antivirus, we recommend using a special tool called Avast Uninstall Utility (avastclear.exe; formerly aswclear.exe). This small tool makes sure your Avast antivirus will be completely removed from your computer with no traces left. Also, it solves the issues when Avast antivirus can’t be uninstalled from Program Control Panel using the standard ‘Uninstall or change a program’ way.

This removal tool can be used for all Avast antivirus solutions (Free Antivirus, Pro Antivirus, Internet Security or Premier) running on any Windows version (10, 8, 7, Vista or XP). Unfortunately, it’s not available for Mac OS X (Mac Free Security).

    I tried to remove Avast Premier trial version at the end of the trial period, after I had issues with the Avast Software, slowing windows on boot up, unexpectedly freezing windows or crashing on loading windows at start up. I am using WindowsXP SP3.
    I followed procedure by going into Safe Mode to un-install Avast but it would not accept this. Each time I tried to go into safe mode and boot up, the HDD was disabled and the boot process kept looping until I had to manually turn the computer off.
    To stay in Safe Mode, I went into config.sys, Boot.ini and ticked the safe boot option. Restarted the computer in safe mode and again, the boot up looped with the HDD disabled.
    I couldn’t load Windows again as the boot process was to boot in safe mode, which had the hard drive disabled.
    I could only enter the bios set up which showed the SATA hard Drive, the CD Optical drive and the option for any external drive all in brackets, saying “a device enclosed in parenthesis has been disabled in the corresponding menu”.
    I didn’t disable the Avast Self-Defense Module and maybe this blocked any access to all the drives.
    Now I can’t do anything to boot the computer up to reverse the safe mode option or
    un-install Avast. I don’t know what to do.

    Some how Avast piggybacked onto my system when I was updating another product. I never launched it, because I use Norton from my service provider, and NOW I cannot get your program to be removed from my system. Your cute little cleaner gets to the point of restart or restart later. Both options fail to do anything.

    I do want to thank you for your funny. “Because we love Avast”, slogan followed by all of the ways to remove your software. My slogan might lean more toward “Good luck chump!”.

    I totally agree with Marc, I spent one day try to uninstall avast an it is impossible.

    I want to install it because it does not work, I try to repair and did not work. I want to reinstall, but I need to uninstall first.
    It is unacceptable for an anti-virus company to release a product which acts exactly like a virus – you can’t uninstall it and you can’t block popups.

    It is a nightmare and I’m running Windows 10. NOt support at all from avast.

    I uninstalled your spammy software and I’m still getting popups.

    Installing Avast was the biggest software mistake I’ve made this year, and I’m running Windows 10.

    I’m sorry to note that this removal utility did not help at all. When I run it, all it says that there are not Avast Installation. When I try to install new Avast, the I get the error message from the installation that it cannot be installed as the previous version has not been uninstalled completely and I should try to use avastclear.

    This info did no good and did not work at all. My Avast internet security suite is disabled, it appears that the software version is a virus itself, there is no way to disable, shut off, or update the software and the version that the software lists is not the same as the last update for 2015.
