Despite what Norton says during the installation, it actually can run with ZoneAlarm if you have SystemWorks (that's with the AntiVirus) and the plain AntiVirus.
First uninstall ZoneAlarm
Install Norton and go through the authentication and all that
Once Norton is on and updated and such, go into Norton Security Center (the icon on the system tray or toolbar)
Under the Norton AntiVirus tab>settings and turn off Internet Worm Protection forever. Security center (windows and Norton) will warn you that there is no firewall on.
Now install ZoneAlarm. Norton should stop warning you because it detects a firewall and Windows Security center will shut up. Now you have the bad azz security levels of the best AntiVirus and FireWall.
