Antimalware Doctor is a fake anti-spyware program that tries to trick users by various methods in order to get them to purchase a license for the software. Antimalware Doctor gets installed on a user’s system via Trojan viruses that get downloaded from websites with fake scanners and from spam email attachments. Once installed, this rogue program loads itself at user logon and performs a large number of fake scans on the system, which return results that state that the computer is heavily infected with non-existent malware. Antimalware Doctor will also display fake pop-up warnings from the Windows taskbar trying to warn the user that the system is under threat. Meanwhile, Antimalware Doctor tries to convince the user to pay for the ‘full’ version of the software by claiming that the currently installed ‘trial’ version is incapable of removing the detected false ‘threats’. However, it should be remembered that the so-called ‘full’ version of Antimalware Doctor is just as ineffective as the ‘trial’ version when it comes to cleaning any user’s system.
