Antivirus xp 2009 is a new rogue anti-spyware program. It is also a clone of Antivirus 2008 - also a rogue, and one that's produced more clones than any other recently. The list of these clones is long: System Antivirus 2008, Ultimate Antivirus 2008, Vista Antivirus 2008, XP Antivirus 2008 etc.
Like any other of it's predecessors, Antivirus 2009 uses trojans, such as Zlob or Vundo, to spread. These trojans lurk in porn/warez websites disguised as video codecs, and, upon entering the system, floods the user with popups and fake system notifications, supposedly to inform him of an infection. While the system at hand may indeed be infected, Antivirus 2009 will inform the user of this regardless of whether it's true or not. The point of this disinformation is to convince the user he is infected and therefore needs an antispyware program to dispose of the threat. The user might click on one of the popups or notifications, all of which claim they will take him to a legitimate security tool, but try to make him purchase Antivirus 2009's "licensed version" instead.
Antivirus 2009 is a scam and should be treated as such: do NOT download or buy it and block it's homepage using your HOSTS file.
