I googled these files and I figured out they are viruses, however, since I have no idea where they are on my computer, and search results of my computer are coming up with nothing, I wanted to see if I could get some help on how to remove these files/processes.
1. csrss.exe
2. winlogon.exe(might not be a virus)
3. atieclxx.exe
4. RtVOsd.exe
any help on how to remove these files would be appreciated. They have caused several problems, Including a blue screen that appeared last night.
