Also keep in mind that some of the AV developers require specific handling
of viruses (e.g. password-protected zipping) before sending them.

Indeed, which is why the McAfee entry appears as follows:

   Network Associates (McAfee)     <virus_research () nai com>
     (use a ZIP file with the password 'infected' without the quotes)

Some of the others may _prefer_ you to do similar or recommend you to 
do so to prevent the attachment being stripped by virus-scanning 
gateways between the sender and recipient (though these days, zealous 
content-filtering gateways will consider passworded ZIPs suitably 
dubious to be stripped anyway), but AFAIK only McAfee "requires" this 
(and even then they will accept non-ZIP'ed samples but weird things can 
happen due to stuffed-up internal message routing resulting in them 
sending you back a malicious file along with a message suggesting there 
is nothing wrong with it).
