There are thousands of nasty viruses/worms looking for unprotected
computers. Your computer can be infected within a few milliseconds
the moment an internet connection is established.
Apparently, your computer is 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:
