XPert Antivirus Enterprise is a rogue anti-spyware program that belongs to the same family as MS Antivirus 2008 and Vista Antivirus 2008. XPert Antivirus seems to be a confused product as if you examine the programs screens carefully, you will find that it calls itself three different names. These names are XPert Antivirus Enterprise, XPert Antivirus 2008, and just plain XPert Antivirus. Regardless of what it is called, this program has one purpose and that is trick you into purchasing it. Typically, XPert Antivirus will be advertised through the use of Trojans displaying fake alerts on your computer or by you receiving a popup when browsing the web. These pop-ups state that computer is running slower than normal or that you have an infection and that you should download XPert Antivirus Enterprise for free. If you click on the OK button, you will then be brought to a page that displays an advertisement that pretends to be a antivirus scanner, and when finished, states that your computer is infected and prompts you to download and install XPert Antivirus.
