A virus appeared on my PC and before I could remove it, it shut my PC down and now whenever I try to boot it up, I get this error. F1, F2, and F8 do not function, so I am unable to go into Safe Mode. I already did a system recovery and backed up all my files, but it doesn't seem to have done anything.
I realize this is little info to go off of, but it is all I have. Any help?
