I was hoping somebody could point me in the correct direction in regards to an open source network wide antivirus solution. I am not concerned with email as we already have virus security in place for that. I am more concerned with virus security for an entire network block. I was thinking of implenting some type of NAT so all traffic from this particular network will go through one machine. What would you recommend to monitor traffic on this machine? Would a client side AV solution be wiser? If so, anything that can be remotely administered?

--Thanks

Are there windows pcs involved here somewhere? If not, why bother with AV?

try clamav:

there's lots of third-party software for it which lets you scan all traffic going through the gateway with it...

Yes, 99% of the clients are windows based machines.

well, there you go... you can scan all the network traffic with clamav...

good luck...

ClamAV appears to be geared towards email scanning. Is it possible to scan all network traffic with ClamAV? All of the modules appear to be for scanning email and I didn't see mention of scanning all traffic through the gateway.

maybe that was the "original" idea... today you can do much more than just email...

YES. it's possible. here's one example which scans lots of traffic:

you can even use it with commercial anti-virus products such as McAfee...

look a little harder, there's lots of options for doing this... there's even a few big corporations that have included clamav in their network appliances and made millions of dollars with it...

my point is clamav is just a virus scanning engine - what you scan is up to you...

good luck...

Thank you very much for the advice. I appreciate the orientation.

you could also use a traffic scanning appliance like Fortinet or Symantec
