For around 89 bucks www.OnlineComputerRepair.org can remove this threat for you right now.

A clone of the well-known fake anti-spyware programs Personal Guard 2009 and Personal Detector, Advanced Defender uses scare tactics to try and lure the user in to paying for a license to the software. Advanced Defender reaches the user’s system via Trojans and other malicious software. Once established on the system, it starts performing endless fake virus scans, returning results that try to convince the user that their system is hopelessly infected. Advanced Defender also effectively blocks any antivirus software that the user may have installed. It also blocks some other useful executables. Advanced Defender repeatedly requests the user to purchase a license to the ‘full’ version of the software, claiming that the currently installed ‘trial’ version cannot clean the detected ‘threats’ properly. However, Advanced Defender is a fake program and cannot scan or clean your computer in any way.

As soon as you find a copy of this rogue software on your computer, you should take steps to remove it. The tasks dealing with how to remove Advanced Defender are listed below.
