Using V2.01.507 - did Registry+Scan for Issues and got result:
Problem: Invalid Default Icon
Data: C:\Program Files\Zone Labs\ZoneAlarm\UpdClient.exe,-279
Registry Key: HKCR\ZAMailSafe\DefaultIcon
Clicked the Fix selected issues button - got message:
"Do you want to backup changes to the Registry" - pressed Yes - Save
Next box said:
"The icon referenced by: ZAMailSafe\DefaultIcon could not be located.
Solution: Delete the DefaultIcon registry key."
Pressed Fix Issue button - got (in green) Issue Fixed
Checked Scan for Issues again - same problem appeared
