I'm still having the same problem. This is after running the avast uinstaller in safe mode then installing avast again. This started after the Windows 10 1607 update on my desktop, but laptop started having this problem and its on Windows 10 1511. There is a bug in the avast application itself due to many people having the same issue. I'm to the point of jumping ship to another application and it sucks because I'm running a paid license.
