Best anti-virus solution for combating LAN viruses

[cpkumar]

In our Institute, there are around 60 computers connected through LAN. Internet connectivity is obtained through VSAT (satellite link). We are having a mail server (linux), squid proxy server (Unix), Sun server (firewall) and a web server (Windows). Most of the times, internet connectivity is very poor. There was no problem found at the ISP end. We believe that LAN viruses are major contributors for slow browsing. In this regard, I wish to know which are the best anti-virus solutions available for our system in the following cases:

1. At server end (linux) - which anti-virus solution and on which server (mail, proxy or SUN), it should be installed?

2. At user end (Windows) - which anti-virus software will be more effective?

Do we also need to install any anti-spam software in the mail (and other) server(s)?

At User end, use Norton 2006 and do regular updates. At the Server use 'F-prot-installer'
(anti-virus for Linux ) . See my post here :

Also users must be prevented from browsing untrusted sites!! That's source for all
problems (viruses, Trojans, spyware, worms come from here!!). You can implement this restriction
at the Server level by filtering the trusted & untrusted websites.
