I need help removing A program that got onto my dell computer.The program is called "Antivirus XP 2008 AGENT". I have know idea how it got on my computer. It keeps poping up saying I have thousands of viruses. I tried going to my control panel to delete it but it wont delete. I used to use McAfee until it expired and then I started using Nod32 and about A few weeks later this Antivirus poped up.Any help would be great. Thanks....
