What is AntiMalware?
The Malwarebytes research team has determined that AntiMalware is a fake anti-malware application. These so-called "rogues" use intentional false positives to convince users that their systems have been compromised. Then they try to sell you their software, claiming it will remove these threats. In extreme cases the false threats are actually the very trojans that advertise or even directly install the rogue. You are strongly advised to follow our removal instructions below.
How do I know if I am infected with AntiMalware?
This is how the main screen of the rogue application looks:
You will find these icons on your desktop and in your taskbar:

How did AntiMalware get on my computer?
Rogue programs use different methods for spreading themselves. This particular one was installed by a trojan.
Extra warning: this rogue tries to remove our program by triggering the uninstaller.
It does not matter what you do with this warning, it will trigger the uninstaller anyway.
Do not click OK in the prompt the uninstaller will display when it is run. Click "No" to stop the uninstall.
