Thanks for the suggestion.  I currently have:

Silent Viruses = HTML-IFrame All-Viruses

The config file says "Zip-Password: This keyword is not needed if you include 
All-Viruses."  "All-Viruses: .... this includes Zip-Password so you don't 
need to include both"

So, what should I set Silent Viruses to if I want all real viruses to be 
treated silently, but I want Zips with Passwords to be treated non-silently?

Basically, how do I say "All-Viruses except Zip-Password"?

Tinned food was developed for the British Navy in 1813.

The tin opener was not invented until 1858.
