Someone has told me that running two firewalls on my machine will protect my machines even more. I'm running a third party firewall at the moment. They also said to run the XP firewall along with my third party firewall. Can anybody please explain, it doesn't sound right to me.

I see no benefit, and possible problems, with running two firewalls.
A good third-party firewall does everything that XP's firewall does,
and more.

I generally agree but for one exception: if one of your firewalls is
built into a router, then a secondary firewall in each PC may be very
useful since the firewalling in most SOHO routers is limited to protection
only against inbound attacks, while software firewalls in the PCs also
supply some protection against outbound attacks (i.e., from Trojans).

I agree with your exception, Bob. It's fine to run a hardware
firewall and a software firewall at the same time.

XP's firewall has no protection against outbound attacks, but
ZoneAlarm and others do.
