    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.

    I used AppRemover for my Mac and it worked out great.

    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~!

  • carmine49 |

    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.

    i just hate avast, didn't know it would be such slippery mount to climb

  • JennWiebeChoiceEnvironment |

    Soon as I attempt to un-install it, the program stops working. Then I have to put the computer in safe mode in order for the downloaded" uninstall app to execute. but even when I remove it the damage is still done and windows wont update and all my windows services like store, pc profiles can't verify and can not get microsoft emails.....they did not respond to my support ticket yet ( 48 hours ) and tech support via phone would not offer help because it was free version. Don't ever get Avast! It will ruin a good week of your life if you try to uninstall it. I am at 6 days right now and still can not get my microsoft or windows apps or programs to work.

    I think , All antivirus do same work but it depands on you how to use these software..But I understand some provide high security and some provide low security to your pc.
