    They both serve different functions in protecting your PC. Zone Alarm (new version pending) is a FIREWALL. This is a virtual wall which stands between you and the internet. It primarily stops any attempt to access your PC by an outside user. It also stops and program on your PC initiating a connection with this same malicious user. This is not related to viruses, per se. A virus is a program which is 'innocently' delivered to your PC, possibly through a firewall, which subsequently launches an attack on the PC and/or attempts to replicate itself (usually today via email). An ANTIVIRUS program, like Norton, is designed to identify any viruses that are on your PC or in memory, and prevent them from replicating or doing your machine damage. To be secure, you will need both a firewall and an antivirus package.

    A quick caveat, you must make sure that your antivirus product is regularly updated, and run; and remember that software firewalls (such as Zone Alarm) have weaknesses...which is why a hardware firewall built into your router/modem is more preferable.
