Can you recommend some software (free or shareware) to monitor and manage the open ports on my PC?

Can you recommend some software (free or shareware) to monitor and manage the open ports on my PC? I've used personal firewalls like ZoneAlarm, WyvernWorks and others but the results are quite discrepant (according to following netstat -a).

I am not sure about WyvernWorks, but ZoneAlarm is a very well rated personal firewall and it takes care of the ports management as well. But since your main problem area is managing open ports, try "Essential Nettools V3.2" or " Ports Lock". They both do a good job in managing TCP/UDP ports while providing other crucial security features.
