System32.exe

Everytime I start my computer an error message comes up saying that I don't have the system32.exe file in my computer. How do I stop this message or what do I have to do?

Are you running an updated anti-virus program? That might be able to take care of it. If you're running ME or XP you'll need to disable System Restore before you scan:
