I have this problem where Youtube, when I try to watch a video, spits out a playback error in addition to another problem which is where every time I try to run a game it crashes on startup. I only just downloaded avast and running a full system scan so it will probably sort out my computer, if not, I will just format my Hard drive and backup all my saves to google drive. I just wanted to know if anyone can tell me the name of this specific virus or problem as it is a very good one (or not I only used windows defender up until now).
