is required to install the firewall, I even have norton antivirus 2007?

Hello, I'm working on a draft. I have three important questions 1) a computer (win XP) has a direct connection to the Internet (with assigned private IP), which has Norton Antivirus 2007 installed, to install the software compalsory firewall such as ZoneAlarm or any other recomonded this system, if not install any vulnerable are things going to happen? 2) 5 computer (they are all win XP) are given connect to the Internet through the proxy server (linux proxy server with private IP is assigned) it is also necessary for firewall security to all this virus (5 Norton machines already installed). ? Please reply. 3) Is it possible for hackers to hack your computer if you have private IP and what are the possibilities that can done by piracy? Thanks

Allows the record straight, because I know how to create trojans / worms and all that good stuff. Nortan sucks. It takes 1 line VBScript to disable a virus. Get ZoneAlarm Pro, ZoneAlarm Pro is free, but has better features. In addition, zone alarm is both anti-virus and firewall.
