For catching the virus itself, try

:0 B:
*  1^0 ^Tvfh9s6oKBjZ3rmrJ8mQiJzLiJ84ZouNAv7VMyN6M
virus

But the big problem isn't the virus - it's the bounces from all the people
that got this virus supposedly from me. These bounces include a anti-virus
spam (anti-virus makers know there is no point in replying to viruses, but
they do so anyway, as a way to "legitimately" spamvertize their products)
and bounces from non-existant or out-of-quota addresses. In the last two
days I got almost 400 bounces (!) and only about 40 copies of the actual
virus.

Pretty soon I'll need to start coding a bounce analyzer, which should only
show me bounces that are relevant to actual emails that I had sent out :(
