Greetings --
You've apparently contracted the latest worm, W32.Sasser.Worm,
specifically designed to attack people who do not update their
computers promptly and who do not practice "safe hex." In other
words, like Blaster, this worm was developed and distributed _after_ a
patch for the vulnerability was announced and made publicly available.
Further, and also like Blaster, this worm could not affect any
computer whose user had taken the basic precaution of using a properly
configured firewall.
To stay on-line long enough to get the necessary updates, patches,
and removal tools, click Start > Run, and enter "shutdown -a" when the
next RPC countdown begins. This will abort the shut down. Also, make
sure you've enabled a firewall before starting, to preclude any more
intrusions while getting the updates/patches/tools.

Because many of the newer viruses and worms, such as the
Spybot mentioned above, can disable antivirus applications whose
definitions aren't kept up-to-date, try using one or more of the free
on-line scanners to double-check your system.
