Windows 8 Black Screen Issue - Avast Setting

I notice that my Windows 8 often goes black screen after logon. I found out that it ties to the Avast! Antivirus trying to block some behavior.

Below are solutions that I tried and it works:

1. Add the following files as trusted application in the Behavior Shield Setting:

C:\Windows\explorer.exe
C:\Windows\ImmersiveControlPanel\SystemSettings.exe 

2. Go to Behavior Shield Setting and Uncheck "Monitor the system for unauthorized modifications"

It works for me.. maybe you can try and leave a comment.
