I have XP pro. Basically, a few days ago I downloaded a program to help with WoW interface and I believe it gave me a virus (yes dumb move, I know). It started screwing with my comp earlier today. No coincidence problems started after I downloaded an unsecure file. My computer rebooted itself for no reason with no warning. Now, whenever I try to log on, it loads up windows and gets to where you can see all the icons and begins to open programs, then freezes and shuts down about 3 seconds later.
Interestingly enough, now (within the past hour or so) my mouse is not working most of the time in safe mode (got it to work like 1/10 times), but my keyboard works. Tried another mouse and it didn't work either, changed the ports around and still doesn't work. Not sure if that has to do with my actual problem or not.
Anyway, back to the real problem:
Often (not always) when it reboots I will get blue screened and get STOP 0x0000007b error.
Other times I will get "a file in your registry had to be replaced with a log or a duplicate, and was successfully replaced" or something similar to that, and then my computer will shut down.
I cannot access windows at all because of this, or I'd download spyware/virus remover. Any idea if this is indeed a virus, and what should I do short of reformatting. I realize I am not a computer pro so take it easy
