For the record:
Zone Alarm is a firewall - firewalls block un-wanted connections to the internet by un-approved programs and/or hackers.

An Anti-Virus stops known viruses/worms from attacking. Viruses/worms don't always embed themselves on your system, Virusesare usually loaded on the system by File Sharing or email attachments, but Worms usually get through via exploits ("back doors") in Windows.
