Really I don't know what happened but I have an idea I got a virus. COuld be from clicking on something I shouldn't have, could be from a strange email that I got the other day claiming I had a package from DHL. I opened it, clikced something, nothing happened thought I was ok.
Today I turned off my computer, it started doing it's updates. Turned it back on later only to find over 2000 files in my document folder.

I am also getting little popups from Windows security alert saying RAM memory usage is critically high

Another saying windows can't find hard disk space, hard drive error. Another saying Damaged hard drive clusters.

McAfee keeps popping up saying it removed a trojan.

Help I am typing a paper!!! I can't have this happen right now!
