antivirus for FreeBSD

[Ben H.]

Hello All,

  Guidance anyone?

I would like to deploy an Anti virus software on a FreeBSD
v4.9 server hosting Samba.

I wanted to look at the Ports Collection... the only thing
I can find there is something called UV-Scan and only
enough extra info to know I can only run it for a month.

I have been considering "Sophos" and can get a two year
contract for under $1k.  That's under $42.00 per month.
(including support for 10 workstations)

I like Sophos but...  are there any other decent options?

Ben
