Windows 8 and Avast black screen problem |SOLVED

Avast Black Screen Problem – windows 8 | solved

You might have encountered a black screen problem after installing Avast antivirus on your Windows 8 operating system. You would notice that once your account loads the screen automatically turns black and you won’t be able to see anything except a moveable cursor.

I recently encountered this problem and I didn’t have any clue as well. I tried to start a new process (explorer.exe) using task manager but looked like it was blocked as it was not appearing under the process tab.  I guessed that it could be Avast,  I’m not blaming avast personally but all antiviruses act weirdly sometimes Tongue Out (My past experience) . The only reason I’m using avast is because its free and also I could get a paid version for free. Want to know more? Read:  How to get Avast Internet Security 3Yr License For Free

    • Try to work in safe mode. Try to hit Ctrl+Shift+Esc a couple of times or Ctrl + Alt + Del in safe mode.
