What a pile of sh**e that is!
I upgraded to windows xp in July, everything went okay apart from when I tried to put the firewall on. Even though xp is a supported os, it just didn't want to cooperate. I think I've uninstalled/re-installed it a total of 10 times since then.
I thought it was okay after the initial problem, but then I found it was leaving a port open. It kept crashing when I tried to block it. Reinstalled and it solved that problem, but then I found out that the function which allows you to block or allow internet access was actually alllowing everything regardless. Another install.

This was friday.
Everything seemed okay. But wait a minute! The firewall then decided to block
everything from accessing the internet. I know I want to surf safely, but this is a bit extreme. So another install.
For some people, it's ntl or microsoft they hate. For me, it's Symantec.
For obvious reasons, I want a new firewall.
Zonealarm pro is an option. Can anyone tell me if this gives you regular security updates like Norton does?
I know Symantec are releasing NPF 2004 at the end of September, so this is also a contender, because it may be miles better.
Anyways, Norton Personal Firewall 2002:
