I wouldnt recommend blocking on all of the known virus email subjects. 
Many of them could be legitimately used.  My director (Boss 3x removed) 
had emails blocked by a filter based strictly on the subject.  He was not 
a happy camper.

Why not block the known unsafe extensions, and then virus scan the rest? 
Clam AV is doing a good job of picking off the inbound viruses for me.
