I changed from zone alarm to comodo firewall which is a free download.I gave up on zonealarm as it was very slow to load at start up and resource hungry, whereas comodo is lightening fast.I find comodo is superb all round and would never go back. Oh,i am on xp.
Have been using Comodo firewall for some time and think it's the best configurable one you can have. Once you explore the firewall the amount of control you can have over it is exeptional compared to other free firewalls. Will take time to find what is what but worth the time.
