Security and Home network

I have a desktop PC connected to the Internet, and a laptop connected to the PC. This has internet availability by using Microsoft Internet Sharing. Both machines are running XP.

On the desktop are Norton Personal Firewall and Norton Antivirus.

I am assuming that all traffic both in and out goes through the desktop, therefore the Firewall and Antivirus on the desktop are sufficient to protect the laptop.

Am I right?

Thanks for the info so far, I'd like to keep the thread open for a lttle longer to see if I get any other replies. Great in depth reply ChrisRLG many thanks.

OK I'm now working on the Laptop. Have carried out both tests.
AuditmyPC reports that I have no open ports.
Shields up reports:
File sharing - all shielded
Common Ports - perfect TRuestealth
All service ports - perfect trustealth

I would understand these results to suggest that the laptop can not be "got at" from outside. Are there any checks I can do to ensure that the Laptop is not trying to get through to the internet on its own?, ie it already has some sort of problem and is trying to connect - would Norton on the desktop stop it. I am on cable broadband.

Thanks for all the help so far
