On performing a scan in my Zone Alarm Extreme Security product (version 10.0.241.000), the scan "froze" at 33%, with the file count stopped. Cancelling and restarting the scan resulted in the progress still showing 33%, while the files scanned counter re-started at 0. Pausing the scan and resuming it produced the same result. Even after rebooting the system (HP dv9820us laptop, Win 7 x64 SP1, 4 GB RAM), the result of the scan was the same, with the file count frozen at zero.
What is happening, and what must be done to resolve this obvious failure?
