MP3 virus?

[Joel Hammer]

I don't see why malicious data couldn't be hidden in an mp3 file. If a
malicious package can compromise sendmail, why not an mp3 player?

I ask because one of my wife's friends had a virus take over their
computer.  They had to call in professionals to clean it up. They were
told the only thing they could point to as a source of the virus was an
"mp3" file.

This seems unlikely, since what kind of virus is going to crash your
computer before it has time to spread? Any ideas?

BTW, knoppix gets even  more points from me. It plays ogg files without
a murmur.
