What this programs does:

SysAntivirus 2009 is a rogue anti-antivirus program from the same family as MS Antispyware 2009 and Nano Antivirus. Just like its predecessors, SysAntivirus 2009 is promoted through the use of misleading web popups and Trojans in order to promote itself. There are typically two methods that SysAntivirus will be advertised on your computer. The first method is when a user is browsing the web and receives a pop-up stating that there computer is infected and that they should run an online anti-malware scanner to check for malware. Regardless of the option they select in the pop-up, they will be brought to a page that displays an advertisement in the form of an online malware scanner. Once the advertisement is finished, it will then state that your computer is infected and that you should install SysAntivirus2009 in order to protect yourself. It is important to remember that this is just an advertisement and has no way of know what is running on your computer. The second method that you may see ads for SysAntivirus is if your computer is infected with certain Trojans that display security alerts stating that you are infected and that you should install SysAntivirus to protect yourself.

Once SysAntivirus is installed on your computer it will be configured to start automatically when you boot your computer and log into Windows. Once running, the program will automatically scan your computer and list numerous infections, which cannot be removed until you purchase the software. These infections, though, are all fake and are only being shown to scare you into purchasing the software. In reality, the only infection you have is the SysAntivirus program and the Trojans that installed it.
