If your /usr/ports tree is up to date you can do this:

% cd /usr/ports
% make search key=virus

which returns several packages, but the one you want is probably
/usr/ports/security/amavis-perl

This does have quite a few dependencies though:

R-deps: arc-5.21e.8_1 compat3x-i386-4.4.20011227 lha-1.14i p5-Archive-Tar-0.22 p5-Archive-Zip-0.11 p5-Compress-Zlib-1.14 p5-Convert-TNEF-0.12 p5-Convert-UUlib-0.201 p5-IO-stringy-2.108 p5-MIME-Base64-2.12 p5-MIME-Tools-5.410 p5-Mail-Tools-1.43 p5-Unix-Syslog-0.95 unarj-2.43_1 unrar-2.50 uvscan-4.16e_1 uvscan_dat-4189 zoo-2.10.1

Note that the amavis port depends on uvscan-4.16e to recognise virus
signatures, and that's a commercial package from Network Associates:
you get a free 30 day trial, after which you're expected to pay.

Other than that, your choices are to cook up some sort of homebrew AV
filter, which can be remarkably effective but will probably suffer
from more false positives and false negatives than a commercial
package.  Eg. see
ftp://ftp.rubyriver.com/pub/jhardin/antispam/procmail-security.html
--- it's described as anti-spam, but it also serves to kill unpleasant
attachments.
