Hm, I'm using the personal version of antivir-milter, installed it just a
few days ago - and for every checked mail, it puts a header like this in:
X-AntiVirus: checked by AntiVir Milter (version: 1.1.0-7; AVE: 6.31.1.0;
VDF: 6.31.1.54; host: theatre.sax.de)

I suspect that something else is wrong. Does your sendmail delegate the
mail to antivir-milter? Is it running? It should write some message into
your /var/log/mailog, here's an example.

Startup:

ug  3 17:20:05 theatre avmilter[16541]: listening on: inet:3333@localhost
Aug  3 17:20:06 theatre avmilter[16541]: engine version: 6.31.1.0
Aug  3 17:20:06 theatre avmilter[16541]: vdf version: 6.31.1.54
Aug  3 17:20:06 theatre avmilter[16541]: addressfilter not active
Aug  3 17:20:06 theatre avmilter[16541]: extension blocking is disabled
Aug  3 17:20:06 theatre avmilter[16541]: running in private mode
Aug  3 17:20:40 theatre sendmail[16570]: j73FKeek016570:

Later:

Aug  3 17:20:41 theatre sm-mta[16579]: j73FKfm7016579: Milter add: header:
X-AntiVirus: checked by AntiVir Milter (version: 1.1.0-7; AVE: 6.31
=2E1.0; VDF: 6.31.1.54; host: theatre.sax.de)

I didn't do anything except following the installation instructions, that
means, I've put the required m4 macro string into my mc file and rebuilt
the sendmail.cf. From that on, it was working instantly like a charm

Oh yes, and with the EICAR test signature it generates an alert mail to the
postmaster and puts the file into the rejected files directory (for my
installation, /var/spool/avmilter/rejected). The only thing I had to change
was the path to sendmail, in /etc/avmilter.conf it isn't set and the
default points to /usr/lib/sendmail - on FreeBSD that's /usr/sbin/sendmail.
