He's probably being truthful. My brother's laptop got the Antivirus System PRO virus last week. Everytime you click on anything on your computer it pops up saying your computer is infected and you need to buy the program to delete it. It even pretends like its scanning your computer. He had to take it to Staples and they ran through the computer and had to remove it. Once you get it, you can't really do anything on your computer. It completely interrupts EVERYTHING you try to do.
