It should be possible.  However, you can't just move the code around. 
The code in filter_begin works on entire message 
(message_contains_virus()).  If you move virus scanning to filter, than 
you will be scanning each part of the message separately, so you need to 
call entity_contains_virus($entity) instead.

Not really.
