A couple of weeks ago ZoneAlarm Internet Security Suite started continuously running a scan. Or, at least, it claims to be running a scan. It's not clear that it's actually doing anything because the number of files scanned does not change in the View Scan window.

Last week in a chat session with ZA tech support I was given instructions to uninstall, clean and reinstall my security suite. I did all that and the problem went away for a few days. Now, the problem is back. The scan icon is always shown in the system tray. If I open the View Scan window sometimes the scan duration increases second-by-second and sometimes it is stuck at 0. Right now, it's increasing but the number of files scanned is stuck at 2343. Scan Progress says "Quick scan..." No detections are reported. Days have gone by with no discernible progress. How can I get this fixed?
