Ever since installing the last update from zone labs for zone alarm pro, My system will not boot up and the zone lab icon is missing from the tray on the bottom right of the screen, I have tried to run from the programs box, but the program won't start.
The hard drive sounds like it is just reading and reading.

How can I get into zone alarm to stop it from running.

Operating System:Windows XP Home Edition
Software Version:7.0
Product Name:ZoneAlarm Pro
