PCSecureSystem is a rogue anti-spyware application. Usually, PCSecureSystem gets into the system via Trojans through browser security holes, and other unethical mechanisms. As soon as it gets into your system, PCSecureSystem will show you an exaggerated scan report claiming that there are hundreds of dangerous parasites in your system. By doing so, PCSecureSystem tries to trick users into buying the commercial version of the PCSecureSystem program. Do NOT purchase it, because PCSecureSystem is designed only to lure Internet users out of their money.
