Personal Emails from "microsoft-Support" to update my system

[Flyer_Bolt]

two times I have received the following mail, sent by:
custumerservice(at)microsoft.com, the attachement however was immidiately
blocked by my Norton 360, saying it contains the Infostealer KB830265:
What´s going on, is that a new cheat?

Text of both mails:

Dear Microsoft Customer,

Please notice that Microsoft company has recently issued a Security Update
for OS Microsoft Windows. The update applies to the following OS versions:
Microsoft Windows 98, Microsoft Windows 2000, Microsoft Windows Millenium,
Microsoft Windows XP, Microsoft Windows Vista.

Please notice, that present update applies to high-priority updates
category. In order to help protect your computer against security threats and
performance problems, we strongly recommend you to install this update.

Since public distribution of this Update through the official website
http://www.microsoft.com would have result in efficient creation of a
malicious software, we made a decision to issue an experimental private
version of an update for all Microsoft Windows OS users.

As your computer is set to receive notifications when new updates are
available, you have received this notice.

In order to start the update, please follow the step-by-step instruction:
1. Run the file, that you have received along with this message.
2. Carefully follow all the instructions you see on the screen.

If nothing changes after you have run the file, probably in the settings of
your OS you have an indication to run all the updates at a background
routine. In that case, at this point the upgrade of your OS will be finished.

We apologize for any inconvenience this back order may be causing you.


Thank you,

Steve Lipner
Director of Security Assurance
Microsoft Corp.

It's a scam. MS would never distribute patches that way.

ummm... Malware.
As stated in numerous threads on these groups, MS does *not* send secucrity
update notifications via email.

Malware most likely.

"The fake alerts describe themselves as part of a new "experimental
private version of an update for all Microsoft Windows OS users,"
Microsoft said in a note on the scam, posted Monday."
