Uninstall it and put in MSE security essentials. I got rid of Norton security and put on MSE never had a problem since. Never need to be reminded to update it does it all on it's own and it is totally free.
I used to use Zone Alarm free and also got a paid for version because it was better than the Windows firewall, until Windows 7 came out.
Windows 7 own firewall is quite good and perfectly adequate for 99% of users. I now only use the W7 firewall. In my opinion, would suggest you uninstall Zone Alarm Free and enable the W7 firewall. I also use MSE as Anti Virus protection.
