This is the first step to remove Avast from your Mac. Select Open Avast Security: When the app window appears on your screen, find Avast Security on the left side of your menu bar and click on it: Find Uninstall Avast Security option and click on that. Avast can't be prevented from starting with Windows during boot, so maybe uninstalling Avast is the only solution. To start Avast uninstall on Mac, click on the Avast icon in your menu bar to open the app. Unfortunately, the only way I currently have of disabling DeepScreen (in Avast 2014.) is to disable all shields! And I'm not even sure that this is working, since I sometimes get DeepScreen popups even with all shields disabled. But DeepScreen popups still pop up!ĬANNOT DISABLE DEEPSCREEN: I've tried disabling DeepScreen entirely (under Settings, Antivirus), since it's so disruptive, but this checkbox appears to have no effect. Going under Settings, Update, Details, you can turn off popups for the majority of them-the annoying update-related popups, which should make it easier to work undisturbed, play video games, etc. (I spent an entire day debugging the installer for a program I'm developing because it suddenly started running twice every single time I launched it- DeepScreen is very forgetful-and only succeeding on the the second run.) It's especially bad if you have Avast set to Silent/gaming mode because then you can get unexpected/bizarre behavior and have no idea why.
As others have mentioned, the culprit is DeepScreen.
