A new Swen-style Trojan horse posing as a critical update
from Microsoft has been detected on the Internet, and users
who open the e-mail message may find their machines loaded
with a back-door Trojan that can steal passwords or be used
in conjunction with other systems to conduct major denial-of-service
(DoS) attacks.
The faux message, which sports a spoofed sending address
of windowsupdate@microsoft.com, uses the subject line 'Windows
XP Service Pack 1 (Express) -- Critical Update' to trick recipients
into opening the attached file.

Several similar email notes are floating around. They look
very processional. For some reason, some of the SPAM blockers,
such as BrightMail, seem unable to stop them.
The best defense is to NEVER open any attached files from
any source you don't trust. When in doubt, take the safe course.
If it's from a friend, but looks manufactured (no personal
remarks from your friend), be suspicious. Ask you friend first
before opening the attachment.
Microsoft never
delivers security updates via e-mail!
