At the morning I downloaded and installed/scanned my PC with PrivaZer and he deleted some kind of files and now my whole PC is messed up, like when i click on google to open a new page it closes or when i try to open something i have to click like 1000 times and the scroll is essed up, everything is scrolling and sometimes when i type its essed like now. I restored my system and the same problem and now i reinstalled my pc (windows 8.1) and still ahve the problem what to do?
