Cloned from Personal Guard 2009 and Personal Detector, Advanced Defender is a rogue-antispyware that tries to trick users into paying for a software license. It gets installed through the use of malicious software and Trojan viruses that are propagated across the internet by scammers. Once established on the user’s system, Advanced Defender loads itself at startup and performs a large number of fake system scans, returning false results that warn the user that the system is under serious threat from malicious programs. It also blocks any legitimate antivirus software that the user may have already installed on the computer. Advanced Defender displays endless fake pop-ups from the Windows taskbar, pointing out legitimate files and executables as viruses. This rogue software then repeatedly urges the user to purchase the license to the ‘full’ version of Advanced Defender, claiming that the currently installed ‘trial’ version is incapable of cleaning out all the detected ‘threats’. However, as Advanced Defender is a fake application, none of its versions can properly scan or clean any computer system.
