System shut down after log on

[Peter]

Dear all,
After logging on, the following message pops up and the
system is restarting in a loop.....the whole procedure is
a circle.
Error message:
"This system is shutting down. Please save all work in
progress and log off. Any unsaved changes will be lost.
This shutdown was initiated by NT Authority#System."

Another window reads:
"Windows must now restart because the Remote Procedure
Call (RPC) service terminated unexpectedly."

Can you help?
Peter

Hi Peter,

Your system is infected by RPC (W32.Blaster) Worm. This is causing the
system to shutdown abnormally.
