So for about a week i keep getting these random errors in event viewer named Event Id 55 ntfs error, to wich when i restart i get automatic check disk and sometimes it reports in a windows balloon notification that CCC.exe is corrupted . Now i haven't installed anything new on this system for a while. Check disk reported no bad sectors and to be safe i formatted and reinstalled windows and after a day it happened again and i was wondering if Avast could be the culprit.
