Who is Vulnerable?
Microsoft Windows clients
Vulnerability Description
Malware is a software designed to infiltrate or damage a computer system without the owner's informed consent. It is a general name for a variety of forms of hostile, intrusive, or annoying programs like Viruses, worms, Adware, Trojans, and spyware that exploit unprotected clients, using network access to intrude upon organizations, destroying or stealing data.

Spyware is computer software that is installed without the user's informed consent on a personal computer to intercept or take partial control over the user's interaction with the computer. Spyware programs can collect various types of personal information, install additional software, redirect Web browser activity, or divert advertising revenue to a third party.

Adware is an advertising-supported software package which automatically plays, displays, or downloads advertising material to a computer after the software is installed on it or while the application is being used.

A Trojan horse is a program that installs malicious software while under the guise of doing something else.  Trojans are known for installing backdoor programs which allow unauthorized non permissible remote access to the victim's machine by unwanted parties with malicious intentions.

Vulnerability Details
The update includes new protections against 2 recent malware threats:

Trojan: Ecodec - Trojan Ecodec (AKA Mmedia Codec) changes the background image of the users's machine, prompt users to download rogue anti-spyware application through pop-ups, and post unnerving alerts on the desktop to scare user's into purchasing such software.

Spyware: Adware_Win32_Ejik - Adware.Win32.Ejik (AKA Downloader Jokcn.H and Trojan.Adclicker) downloads additional malware onto a users computer and changes browser's settings by adding a banner to the browser's page. It constantly sends HTTP request to affiliated advertising servers.

Protection Overview
The update enables the Header Rejection protection to detect and block the malware based on pre-defined header names.
