Someone responded to my original post (subject: xmp) by directly sending me
a message from a yahoo address that contained the MTX virus in a file called
You_Are_Fat!.txt.pif - only text in the email was "Take a look at this."

Obviously, I didn't execute it.

Hey, maybe my question was a bit irritating and newbie-ish, but I don't
deserve that kind of crap.  If on the off chance someone had a yahoo account
hooked up to their windows email client and was trying to send me a real
answer to my question, you have the mtx virus - here is a link that shows
what to do about it:
