Defense Center is a malicious anti-spyware application that has been derived from a number of rogue programs, namely, Digital Protection, Dr. Guard, Your Protection , Data Protection and Protection Center, and tries to trick users into purchasing its license. This malicious application reaches the user’s computer via Trojans that get downloaded from malicious websites. Once established on the user’s system, Defense Center loads itself as a startup service at boot time. Defense Center proceeds to perform a large number of fake security scans on the system, returning results that state that the computer is dangerously infected with a number of non-existent viruses. It also generates fake warning pop-ups from the Windows taskbar. Finally Defense Center urges the user to purchase a license to the ‘full’ version of the software, claiming that the currently installed ‘trial’ version is incapable of cleaning the detected false ‘threats’. However, all users should be aware that this is a trick aimed at swindling their money, as no version of Defense Center can scan or clean any computer.
