    If you need to remove Avast 7.x from many Mac or PC devices (e.g. when doing a mass replacement of AV) in a scripted/automated manner there is a tool called AppRemover On Demand from OPSWAT that supports that approach. It can be used on up to 3 Mac/PC devices for free. Thereafter you need to buy a license from them; they price it based on usage.

    RE: Mac solution.... After uninstall still have avast in system preferences. Also in users/username/library/application support avast folder still present.

    I have a feeling that avast has caused intermittent booting problems for my mac, searching elsewhere for alternative solutions.

    @Swilliams: Many applications leave behind files in Application Support on Mac. I recommend using a cleaner such as AppCleaner.

    I goofed. I used IObit Uninstaller which works great on everything EXCEPT Avast. I can't go to permissions and get control to get rid of the program left behind in my Program Files.

    If Avast is this user unfriendly, I don't want it anymore.

    Anyway, I read BitDefender is the best anti-virus software to get.

    Multiple daily popups of Avast wanting me to renew does not leave me a happy camper~!

    I hate Avast. Once you've loaded it onto one's computer, it is the devil to uninstall and get rid of. I used iObit uninstaller, which left Avast software on my harddrive. I can't figure out out to wrest permissions away from the system to delete this software. BEWARE if you install Avast. BitDefender is considered the best anti-virus software. I've downloaded the limited free version. We'll see how that works out.
