Fake MS Security Update for Explorer.exe

Websense® Security Labs™ has received reports of a email scam disguised as a Microsoft Security Update for Explorer.exe. Users receive a spoofed email message instructing them to click on a link to immediately download and install a bugfix from Microsoft.

The link in the email takes the user to a fraudulent website, designed to appear as the legitimate Microsoft Windows update site. The security update hosted on this page is actually a backdoor Trojan horse.
