Antimalware Defender is a rogue anti-spyware application from the same family as Virus Doctor malware. This rogue anti-spyware application is usually distributed through the use of Trojan virus or other malware. Once installed, Trojan virus displays fake pop-up that looks just like the Windows Critical Update window, so replacing the routine installation of such rogue programs. The fake Windows update notification reads:
Antimalware security update for Windows XP (KB961118)
This critical update will install System Security Update 2010.01.023 (Antimalware Defender Upgrade; KB648759)
A funny thing is that an update with code name KB648759 doesn't even exist in Microsoft database. Then, Antimalware Defender GUI will pop up on your screen [Figure 1]. It's almost an exact copy of Windows Defender which is perfectly legitimate anti-malware software.

Then it will ask you to pay for a full version of this fake program in order to remove the infections that we already know doesn’t even exist. Don't buy it! Further more, the rogue program will display fake notifications and warnings claiming that your computer is under attack or badly infected with viruses. Last but not least, Anti-malware Defender will install randomly named browser helper object.
