It seems that you have a similar issue with this user: https://forum.avast.com/index.php?topic=168497.0
However, your issue is not as severe as that user since that user got BSOD (You can refer to the pic shown on the first post).
I looked at the pic, it seems that user had a much more severe problem. I don't have BSOD, I don't understand that language so I can't tell what's being said. (Chinese or Korean?) But it seems you referred to this thread in that other user's thread. Is their problem extremely similar? (Bar the fact they're getting Kernel errors)
