This virus, like nearly every vaguely "successful" self-mailing virus 
for the last two or more years forges the From: header _and_ the SMTP 
envelope From:.  Your "solution" is only adding to the problem by 
increasing the unnecessary bandwidth needlessly used by this virus 
_and_ confusing the hell out of a lot of perfectly innocent bystanders 
you have now accused of being virus-infected.

I'd recommend you pull your head out of your BSD (Big, Smelly, Dumb) 
arse, pick up the clue-stick and beat yourself senseless with it.  When 
you come round, have your colleagues repeat the procedure on you.

Sheeesh...

Unix bigot "experts" -- it's a good thing for you Unix is not the 
preferred OS on the Internet or yesterday's thread about clueless MCSEs 
would have been about you and your buddy clueless UCSEs...
