He has a reason: that virus was melting down his network (and was 
melting down lots of networks).

If viruses came with instructions, documentation, and source code, we 
could all rest assured that it did completely self-destruct this month. 
  Instead, we're all watching in wait, and leaving filters handy or in 
place.

(I'd mention the Nachi filtering I had to do and the implications of how 
I had to do it based on the platform I'm using, but my flamesuit is all 
tattered just trying to find a safe tool to read my mail.)
