my $size = (stat($entity->bodyhandle->path))[7];
if ($size < 10000000) {
  # scan it
}

(note: that's 10 MB, not 10,000k or 10 MiB <g>)
This should be in filter and the "scan it" part should call
entity_contains_virus.

If you use something like the default filter, keep in mind that you
already scanned the whole message in filter_begin.  If you're trying to
avoid that too, then you'd have to put something in filter_begin to see
if any of the files in the work directory are too big, then decide to
call message_contains_virus or not based on that.
