Antispyware 2009 is another clone of rogue-antispyware software family (Antispyware XP, XP Antispyware, Antispyware XP 2009 etc.). Usually you can be infected by this useless software with the “help” of Trojan Horse while downloading fake videocodecs. Once Antispyware 2009 will contact with your system, it will generate a lot of fake pop-up messages reporting that computer is seriously infected. This is the way how Antispyware 2009 developers try to scare computer users and trick them into purchasing Antispyware 2009 for about 30 $.
