Security Guard 2012 is part of the so-called Rogue.WinAVPro family. It is a fake anti-virus application, which cannot remove any infections, but insists on being a legitimate program and prompts people to spend money on its bogus full version.
Security Guard 2012 uses a number of con strategies in order to convince users in its legitimacy. To start with, the rogue enters vulnerable machines with the help of Trojans that are laid in compromised websites. When it manages to sneak into the PC, Security Guard 2012 starts producing a variety of phony alerts and notifications, such as the ones below, in an attempt to scare the victim:

What the rogue will also do is to perform a counterfeit scan of the system. The outcome of its scans is that a lot of viruses have been detected running lose in the computer. Do not trust the list of infections it produces, it is made-up. When the scans are over, the program always prompts the user to pay for its phony full version. To achieve its malignant plan, Security Guard 2012 is also capable of blocking other applications, claiming they have been infected:
The file .exe is infected. Running of application is impossible.
