Go into the Start menu - Programs - and the ZoneAlarm entry, right click on the uninstaller and select 'Properties'. In the target box add a space and then /clean to the end so it looks like this: C:\Program Files\Zone Labs\ZoneAlarm\zauninst.exe /clean then click 'Apply' and 'OK'. Open ZA and turn off the load on boot option (under Preferences), reboot and then run the uninstaller (the one you changed the shortcut for). This will get rid of ZA. Go to the Windows temp folder and delete everything, then find the folder named Internet logs, delete it, then empty your recycle bin. ZA should be gone.
