Greetings --
What you received is the output of a computer infected by one of
several widely publicized, wide-spread, mass emailing worms. The
virus' authors have deliberately spoofed the Microsoft information in
the hopes of garnering more victims. This sort of email has been very
common for at least the past year. The most widely-known are:
W32.Swen.A_mm
http://securityresponse.symantec.com/avcenter/venc/data/[email protected]
W32.Dumaru_mm
http://securityresponse.symantec.com/avcenter/venc/data/[email protected]
W32.Gibe_mm
http://securityresponse.symantec.com/avcenter/venc/data/[email protected]
Trojan.Xombe

Microsoft never has, does not currently, and very probably never
will email unsolicited security patches. At the most, if, and only
if, you subscribe to their security notification newsletter, they will
send you an email informing you that a new patch is available for
downloading.

How to Tell If a Microsoft Security-Related Message Is Genuine

Remember, any and all legitimate patches and updates are readily
available at
http://windowsupdate.microsoft.com/. You should develop
the habit of checking this site at least once a month to keep your
computer up-to-date. (Notice that this is the true URL, rather than
the bogus one that may have been contained in the email you received.)
Any messages that point to any other source(s) or claim to have the
patch attached are bogus.
You're receiving these emails because your email address is in
the address book of someone infected with a worm, and/or because you
posted your real email address somewhere on-line, either in a forum
accessible to the public and spambots, such as Usenet, or on an
untrustworthy web site that subsequently sold your address as part of
a mailing list. One thing you can do is notify _everyone_ with whom
you've ever corresponded via email that one or more of them may be
infected with a mass emailing worm, and should take the appropriate
steps. You can also ask your ISP to take steps to preclude their mail
server from passing on such emails. Many ISPs have such filtering
capabilities.
