Uvscan is McAfee's antivirus product. Did you install it? There's a conf
file in the files directory of that port. It defines AVSCANNER as
"/usr/local/bin/uvscan". That would require that you have McAfee
Antivirus for FreeBSD installed. If this machine handles lots of mail, I
wouldn't suggest you use that. Uvscan launches a shell for each time it's
called, and it will suck a lot of cpu and memory (based on our extensive
comparison testing.)
I would recommend that you install either clamav (security/clamav) or your
school's commercial product *if* it has a daemon for FreeBSD. If it's a
shell program like McAfee, I would *not* recommend it.
Once you have the av product installed, edit the conf file appropriately
and you should be up and running. You'll find the conf file in
/usr/local/etc.
