Pest Detector Virus Removal Guide

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: Pest Detector is a malicious fake anti-malware application that is an exact clone of Red Cross Antivirus, Peak Protection, Major Defense Kit and AntiSpy Safeguard. Pest Detector installs itself on user systems through Trojans that get downloaded from fake security websites which exploit vulnerabilities in the system's security to get downloaded and installed without the user's knowledge. Once installed, Pest Detector immediately loads up as a Windows service, and proceeds to perform an endless number of fake security scans on the system. As a result of these fake scans, Pest Detector will report that there are viruses present on the system which are not really there. It will also generate fake security pop-ups from the Windows Taskbar, trying to convince the user that the system is infected. The aim of all this activity is to push the user into purchasing the license for the 'full' version of Pest Detector under the pretext that the currently installed 'trial' version is incapable of performing the cleanup activities needed to save the system. However, you should remember that the viruses that Pest Detector detected didn't exist in the first place, and therefore you should never pay for the license of such a fake application.
