I have Norton firewall running which seems to 'catch' a lot of attempted
attacks on my PC.

Is there any point in having a second firewall running (Zone alarm perhaps)
simultaneoulsy for 'double' protection. Might they interfere with each other
?

Thanks

Absolutely not. Two software firewalls should not run simultaneously
because they will conflict each other : Computer crash, lose internet
connection , lower protection level.

But you can run one software firewall + one hardware firewall at the
same time.

Hardware firewall is quite expensive, compared to software one.

NAT router with SPI ( stateful packet inspection ) feature will provide
you pretty good protection. NAT/SPI router is not actually a hardware
firewall, it has firewall function.

I am not very good at networking, if you have further questions
concerning routers, please feel free to ask other people.
