i would reinstall zonealarm, making sure you get all the leftovers after the uninstall, such as registry settings etc.. ....after a reinstall and you get the same issue then i would use a different firewall. there are several to choose from but the 2 i use on my computers are zonealarm and kerio personal firewall. kerio is pretty good, its the same setup as tiny personal firewall.

kerio is free for home & personal use just like zonealarm.
