I made the mistake of having two antivirus programs, and I did it twice. Sigh...you guys ever heard of "system restore"? That's what I had to do. Thank God I had a restore point, now I just pray nothing goes wrong here...
I have too, I thought...but I know one was just expired...I think a big part of my troubles was also downloading a bunch of other stuff at the same time so it just totally destroyed my computer's performance.
