Major Defense Kit Removal Instructions

Update 10/16/2010 :  You may want to also check out this related guide:  Fake Microsoft Essentials Warning .  This is the first part of the virus and we have included a video to help people remove it as well.

Description: Major Defense Kit is a notorious rogue anti-malware program cloned from a set of malicious software: Red Cross Antivirus, Pest Detector, Peak Protection and AntiSpy Safeguard. Just like other fake antivirus applications, Major Defense Kit attempts to push the user into purchasing a software license to the software which does not help the user in any way. Major Defense Kit reaches user systems thanks to a Trojan that hides in malicious websites and then gets downloaded on to user computers when they visit the malicious websites. Once installed, Major Defense Kit will load itself up as a startup service with the help of the Trojan, and then it will proceed to perform a large number of fake antivirus scans on the user's system, subsequently reporting that there are a dangerous amount of viruses present on the user's computer. Major Defense Kit accentuates these claims with fake virus warning pop-ups that get generated from the Windows Taskbar. All these actions are aimed at tricking the user into paying for the 'full' version of Major Defense Kit by tricking them into believing that the currently installed 'trial' version of Major Defense Kit cannot remove the detected 'viruses' properly. However, you should always keep in mind that Major Defense Kit cannot remove any viruses from your computer under any sort of conditions.
