For some reason I havd recently started getting a message that Truevector has had a problem and has shot down, would I like to restart it?

I say yes, for the same message to come up 30 seconds or so later

Whilst this problem persists I am unable to access Internet

Shutting down ZoneAlarm completely allows me to use Internet - but unprotected

I have uninstalled ZoneAlarm and reinstalled - same thing

I am using Windows 7 64 Ultimate

Can you help?
