Avast Secure Browser keeps closing with seconds of opening. I've tried updating, Uninstalling, and Reinstalling to no avail. I've updated Windows 10, attempted a restore, and experimented with both Chrome and Windows Edge. Nothing I have done seems to make a difference. I'm sure that I am missing something, but can not figure out what that might be.
It was working perfectly up until a few days ago. Please help me fix the problem. Thanks.
