Agree, a message would be good.

True. But this solution offers two advantages:

a) it's a quick hack, it works (apparently), and it was easy to
   do it on a tuesday morning without installing all kinds of
   additional filters.

b) I never have to store the crap on my own system. Let the windos
   users choke on it, even at ?1/GB my harddisk space is too
   expensive to store their virus spam.
