Cool virus I got from AIM

[David04]

Okay, so I have this virus on AIM that sends a message to everybody on my buddy list like "Check out this game" or "kill some time with this" or whatever. Then if somebody clicks/downloads it, the same thing happens to them. It does it over and over, all day. My friend told me it sent it to him even when I wasn't signed on.

I know there is a .bat file that was created. I found this and deleted it, but it comes back and still keeps sending the messages. Any suggestions are appreciated.
