I've used ATGuard for years. When Norton bought it, I tried their bloated, awful, expensive version and rapidly went back to using ATGuard in its original form. It has never failed me, as far as I'm aware, and I love its simplicity and array of features. The only problem is that it hasn't obviously been updated in five years. So recently I've been wondering if there are intruders around nowadays which contain technology that can circumvent ATGuard, so that once running on my disk they are able to connect out to the internet without ATGuard knowing? If so, what firewalls should I look at, for Windows2000 SP4? I've tried ZoneAlarm and absolutely hated it. Comodo seems to be getting mixed reviews. I don't mind paying for a new firewall. cheers.
