Upgrade to
ZoneAlarm Pro v8.0.059.000. It shuts down and starts up faster than ZAP v7. If you are using any other anti-spyware for realtime scanning then you can turn off ZAP's anti-spyware, which will speed up ZAP and your comp. You can also turn off ZAP's anti-spyware if you are using an anti-virus which is good at detecting spyware(like Kaspersky AV).
Depending on whether your ZAP v7 license is purchased or pirated, it may or may not work with ZAP v8.
