XP Professional

[David Gower]

Workstaion will shutdown randomaly with error saying that
the RPC Service is unexpectedly termnated. This was after
2 viruses files were found. The files effected were
cxaaq.exe (w32.sdbot.worm.gen.b virus) srvhost.exe (proxy-
FBSR.gen virus) and regsvc32.exe was (w32.sdbot.worm.gen.b
virus).

The symptoms appeared at the same time the viruses did.
The only way I could clean the viruses is to delete the
files, I cannot find those files on anyother WinXP
installation. The problem still exsists. Can anyone
please assist.

Your computer could be infected with the Baster worm.

Greetings --

It sounds as if you've been collecting worms.

If you connected the PC to the Internet without having first
enabled a firewall, without having first installed an antivirus
application with current virus definition files, and before installing
the KB824146 Hotfix, you're very likely to get infected from any of
the thousands of PCs on the Internet that are constantly broadcasting
the Blaster and/or Welchia worms. It only takes a few seconds of
exposure.

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.
