As with any other fake anti-spyware that is part of the Fake Microsoft Security Essentials infection, Windows Amrour Master infects a computer via a Trojan that once on the system in question it will start displaying fake Microsoft Security Essentials alerts stating that an Unknown Win32/Trojan has been detected on the computer.
The alert messages will then suggest that you scan your computer, a process that is fake and meant to scare you into thinking that your machine has been infected with Trojan.Horse.Win32.PAV.64.a. The fake alert messages will then suggest that the only way to remove this threat is by installing Windows Amrour Master. Clicking Ok on these alert messages will automatically download and install Windows Amrour Master on your computer, after which your system will reboot.
After the reboot you will not be able to access your regular desktop screen. Instead you will see a Windows Amrour Master main window suggesting that you should perform another (fake) scan. Once the fake scan is completed Windows Amrour Master will attempt to scare you into thinking that your computer has been infected with a multitude of threats and that the only way of getting rid of these infections is by purchasing the full version of Windows Amrour Master.
Do NOT let yourself scared into purchasing this so called full version as it is just another fake program meant to get a hold on your money and credit card information.
Also keep in mind that in order to access your regular desktop screen you will need to go through the (fake) scan every time you reboot your computer.
