There are thousands of nasty computer viruses/worms looking for unprotected
computers. Your computer can be infected within a few milliseconds the
moment an internet connection is established if your computer is not
properly secured.
You PC may be infected with the W32.Blaster.Worm or one of its variants.
This happened because you have not been using an internet connection
firewall and have apparently neglected to install the critical updates
available at the Windows Update website.
If your computer is constantly attempting to shutdown or reboot, quickly go
to:
Start > Run and type: CMD , and hit enter. This opens the Command Prompt
window.
Then type: shutdown -a , and hit enter.
This should halt the rebooting problem.
------------------------------------------------------------------
Then immediately turn-on Windows XP's built-in Firewall:
