If you reinstall Zone Alarm, do a 'clean' uninstall of your present firewall first. Go into the start menu locate the zonelabs entry and right click on the uninstaller and select properties. Now in the target box you must add a space and then /clean to the end so that it looks something like this "C:\Program Files\Zone Labs\ZoneAlarm\zauninst.exe" /clean click apply and then OK. Next open ZA and turn off the load on boot option, then reboot and then run the uninstaller.This should get rid of all of ZoneAlarm. Now go to your windows temp folder and delete everything. Find the folder named Internet logs and delete it then empty your recycle bin.
