Okaay, so I guess I really fucked up my computer now, here''s the basic setup:

I don't know what I did, but I was notified by someone they were getting odd MSN messages from me, I located the file through a scan, deleted that, and it still persisted. So I tried the safe mode system restore, several different times and dates, and none of them are working. The computer locks up after a few moments, and I have to use Task Manager to force the programs to start and enable my taskbar and programs on the Desktop. I am at a loss of what else I can do. I don't know if it's the computer, a program, or a virus, and with it locking up I can't really check. Any ideas?

I'm using a seperate computer that isn't mind to do this, so yeah. I'm gonna go crazy here soon without my own computer to use and such. I backed up all my files and such to an External Hardrive, so it's okay, but I can't get the system restore to work, and I don't have a new OS disc (Nor the money for one), and lack the knowhow to even scratch my computer. But if I could, I just might. I really want to save my PC though!

I'm running on Windows XP right now and such, and yeah, I'm just stressed out now and freaked and such. This blows majorly. x.x Why can't people just leave my POS alone? D:
