Email scams are a common way to spread malware and/or steal personal information. Some great guidelines to help you protect yourself from such scams are outlined here: http://www.microsoft.com/protect/computer/viruses/email.mspx
We have recently found out about the latest in an ongoing string of email scams that target Microsoft customers. This particular scam contains the Backdoor:Win32/Haxdoor trojan as an attachment. We have seen a few emails targeting Microsoft customers that look like the email below:
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.
Director of Security Assurance
