AaronXP, Crispy, Doggie - why do you like Kerio? I'd never even heard of it before this thread. I'm using ZoneAlarm Pro v4.0 right now. I'm always interested in trying new things. Maybe I will install Kerio Personal Firewall2 v2.1.5 the next time I reformat. Please tell us the reasons you choose it over other firewalls.
