I have networked 2 PC's for internet sharing and am not sure if I need anti virus on both machines or just the host. I know I only need one firewall to protect both.

Thanks for any help.

Re: Networks and antivirus

You should have an anti-virus program on both machines, as the one with the Internet Connection Sharing software on it is just passing data through it without touching it (for all intensive purposes). Anything that you download to the machine that isn't directory connected to the internet doesn't get handled by the first machine.

So, have anti-virus software on both machines.

Re: Networks and antivirus

I agree with Rob: invariably the machine that opens the infected e-mail attachment will turn out to be the one without virus protection!

A good little program is AVG, a free download from http://www.grisoft.com It automatically updates it's virus definition and can scan before OS start, at certain times during the day or week, or on command. It will also scan individual files if you so choose.

Hope this helps.

I have the same setup and I am just running some http://www.sophos.com software on each machine. So far so good, except the fact that one machine is XP and the other is Windows 7. This is not a software issue, it is just interesting in that I get some variance in detection across the two machines..
