I understand XP (I have the Home version) has its own firewall.
Yes. Both XP Professsional and Home has this feature.
If
this is correct (is it activated automatically?),
No. From Windows Help and Support:
"Click Start, point to Settings, click Control Panel, and then
double-click Network Connections.
Click the Dial-up, LAN or High-Speed Internet connection that you
want to protect, and then, under Network Tasks, click Change
settings of this connection.
On the Advanced tab, under Internet Connection Firewall, select
the Protect my computer and network by limiting or preventing
access to this computer from the Internet check box."
then is there any
need for the Norton program?
Although the built-in firewall is OK, it has two important
limitations:
1. It monitors incoming traffic only, and does nothing about
rogue programs trying to call home.
2. It's not very configurable.
For those reasons, I prefer other products on the market, such as
the free version of ZoneAlarm. But run only one firewall, not
two. Running both adds no extra protection, wastes resources, and
subjects you to the risk of conflict between them.
