[CentOS] can I use CentOS as a antivirus / spam filter / HTTP AV gateway?

Hi all

I've been thinking about using CentOS on a Dell R200 server and turn it 
into a firewall / network monitor / traffic shaper in our datacentre, 
instead of using a dedicated firewall device.

One of the devices that I have been looking at, with my limited budget, 
is the D-Link DFL 860 -

It provides AV, SPI, VPN, DOS, P2P, etc protection. Most of this can be 
done with Linux as well, but I'm not 100% sure about the AV part.

How will I use / setup CentOS to check all traffic coming in & out 
(HTTP, SMTP, POP3, IMAP, etc) for virusses and clean them? We host both 
Windows & Linux servers, and I'm not too worried about the Linux 
servers, but Windows needs a lot of extra protection.
