Avast reacts to everything

Hello im having big trouble with Avast right now like 1000 other people
avast reacts to everything and says that its malware
i think its better understandable for you when i post this reddit link cause aloooot of people have the same issues
avast also says that 50 files are infected but i cant repair or delete them
(i allready updated avast)
and also reinstalled windows!
in this link they talk about my problem
