[FastAntivirus2009 is a fake antivirus.

This adware, like all of its
kind, simulates a system scan, detecting several malware variants which
are really not on the computer. Then, it offers the possibility of
disinfecting these 'viruses' by purchasing a paid version of the false
antivirus. All this aims at getting financial returns from this
malicious code.]
