Windows restarts because "DCOM Server Process Launcher service terminated unexpectedly"

Dell Precision 340 running XP Pro and Norton Anti-Virus Corporate Edition.  Installed PCTools SpyDoctor (full version) two days ago.  Got rid of my spyware problems (I think) but now whenever I turn on the machine about a minute or so after windows loads i get a timed shutdown message that says:

"Windows must now restart because DCOM Server Process Launcher service terminated unexpectedly. " The shutdown is initiated by NT AUTHORITY\SYSTEM

This occurs in safe mode as well.  If I can manage to log in to windows quick enough, I can stop the shutdown by issuing "shutdown /a" from the command line.  Once that is done I don't seem to have any problems. . .

Thanks in advance for your help. . .

you definitly have some form of malware.  Maybe try running stinger and see if it picks anything up.

you are going to need to clear the offending virus off the machine and uptate to the latest microsoft patches. If i recall correctly there was a patch a while ago to stop the DCOM exploitation, but i could be down to correction.
Run msconfig and stop SpyDoctor see if it stops error.
that sounds like a sasser/blaster variant.
when you scanned your machine for malware did you find anything? if so and it was removed did you disable system restore?  Not disabling system restore first could lead to reinfection.
What version of corporate are you running.  Versions before 9 (I think it was) wern't very good at removing malware.  Upgrade to 10.1 if possible.

Unchecked everything in msconfig that listed Spyware Doctor.  No result.  Uninstalled SpyDoctor Completely -- still no change.

Southie: "when you scanned your machine for malware did you find anything? if so and it was removed did you disable system restore?"  -- YES
"What version of corporate are you running."  -- Older than 9  :-(  Upgrade is not really "in the budget"

Thank you both for your responses.
Steve Gibson has produced a tool to disable DCOM:

This may help...

Thanks all.  Stopping Monitoring of this issue.  Thanks again.
I get the error message that states that the system shutdown is being initiated by NT Authority/System and that Windows must now restart because the DCOM service process launch service terminated (which means I either have to use shutdown -a or reboot) BUT a McAfee scan picks up no virus, the stinger application picked up no virus and when I used Steve Gibson's tool I was told I have no DCOM service becausse I am running XP service pack 2.
