Privilege escalation vulnerability in the Self-Defense driver of Avast Antivirus prior to 20.8 allows a local user with SYSTEM privileges to gain elevated privileges by 'hollowing' process wsc_proxy.exe which could lead to acquire antimalware (AM-PPL) protection. Multiple privilege escalation vulnerabilities in Avast Antivirus prior to 20.4 allow a local user to gain elevated privileges by calling unnecessarily powerful internal methods of the main antivirus service which could lead to the (1) arbitrary file delete, (2) write and (3) reset security.

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.
