Got a virus..what can I do?

[Jesus Shuttlesworth]

Well I got some type of virus - I can't get on internet explorer or into My Documents, My Computer, Recycle Bin etc. I can still gain access to these folders if I go through "run" in the start menu.

When I click on any of the shit that doesnt work, a message pops up telling asking me if I want to send an error report. Sometimes the Error Report question pop up just comes randomly too.

Is there anything I can do without reformating? I have no idea where my XP disc is, I got this computer as a favor sort of so I don't really have any of the shit that came with it.
