Problem #1: When I open Avast free antivirus user interface (20.3.2405) my mouse clicks does not work anywhere on the screen. I have to press alt+tab to make it to work. I was facing this problem in earlier versions also. However, updating it to latest version has not helped.
Problem #2: Notifications from Avast stays on the screen for about 2 minutes. My attempt to close it by mouse does not work. Possibly related to problem #1.
I could not even click on "About Avast" on the system tray. I had to use the keyboard with tabs and then use enter to get the version information.
I am using a USB mouse. Win10 Home 1909 18363.778). However, I have had this problem for about a year now and I don't think it is related to Win10 version.
How do I get this resolved? These have become very annoying.
