Network AV server

[Joshua Lewis]

Could someone point me in the right direction to create a network server
that scans networks systems for Virus and acts on the viruses accordingly.

I have a FreeBSD system that I would like to turn into a virus scanner
(among other things) but I don't know how or what scanners are available
and/or recommended.

Recommendations and links to possible how tos are welcome.


Thank you,
Joshua Lewis
