If your using an Instant Messenger program like MSN Messenger or Yahoo! Messenger, just block the kid so they can make no contact with you on the program.
Also, If you say the kid is an idiot, He could have tried to send a virus to you using some kind of sender but screwed up somewhere. Just don't open it. Hope it helps
It Could Be A Buddy of yours playing a little prank by sending you a fake Virus or something , But other than that scan it or check the data extension.
