********************************************************************************************************************************

PC Defender is a rogue anti-spyware program that is installed through Trojans. The Trojan installer pretends to be a program that is needs to be installed before you can view an online video. Once you install the Trojan it will download and install PC Defender on to your computer without your permission. When the rogue is installed it will be configured to start automatically when you login to Windows. Once running, PC Defender will scan your computer and list a variety of infections. It will not allow you to remove any of these infections, though, until you first purchase the program. In reality, the infections it shows are legitimate Windows files that if you delete could cause your computer to not operate properly. Therefore, please do not act upon any of the scan results this program may show you.

It is possible that the infection you are trying to remove will not allow you to download files on the infected computer. If this is the case, then you will need to download the files suggested in this guide to another computer and then transfer them to the infected computer via a CD/DVD, external drive, or USB flash drive.  If this is not possible see the RescueCD’s section on home page.

SUPERAntiSpyware Online Scanner

SUPERAntiSpyware Portable Scanner can be downloaded from a different computer and run on the infected computer. The scanner does NOT install anything on your Start Menu or Program Files and does NOT need to be uninstalled. It runs from the CD and requires NO internet connection. If the infected computer can not download, then this is a solution. Simply download the portable scanner and copy it to a USB/CD. NOTE: The portable scanner is random named to prevent the malware from stopping the scanner from running. For more software similar to this see the RescueCD software section on home page which scan an infected system and can recover personal data due to infection/defective or failing hard drive.
