I have been having occasional errors with the Remote Procedure Call which forces a reboot in 1 minute (running Windows XP SP2 with all updates). I searched online and found information linking it with a few viruses, most namely the old MSBlaster worm. I did a full scan with Symantec Anti-virus and found one virus and removed it. Further scans are clean. The system is also clean when scanning for adware/spyware with SpyBot and Adaware. The error seems to occur randomly and not connected with any certain activity and can happen anywhere from once a day to around once a week. It can be cancelled with the "shutdown -a" command.
Any ideas on where to look for the ghost in the machine? I had similar errors around 1.5 years ago and cleared up on its own.
Cheers,
Tom
