This morning I launched my laptop, then the posted a percentage number, next to it it said along the lines of "Please wait. Cleaning your drive C:", I found it really fishy so then I ran MalwareBytes. It said everything was fine so then I started going through my day. Then this happened. I was playing CS:GO, in the middle of a match then it disconnected me saying something about I couldn't connect to VAC servers because there were files on my system that prevented me? So then I was really suspicious now, so then I ran MalwareBytes Chameleon, but it said there was an error with my anti rootkits. I then tried to launch MalwareBytes again and it says I don't have the appropriate permissions. Help please.
