     Your friend has 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 Shutdown 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.
