I purchased Zone Alarm 7.1 some months ago. Seemed to be working fine, but recently discovered that the when I
tried to do a
System restore, (Windows Vista SP1)
the Restore function would not operate. Received error message: System
Restore did not complete succesfully.........Details: An unspecified error occurred during System Restore".

a clean re-install of Windows Vista, by by trial and error I discovered that this problem occurs only after I install Zone Alarm.
If I then uninstall Zone Alarm, the Windows System Restore function works again!
Any one able to assist me with this

Operating System:Windows Vista Home Premium
Software Version:7.1 (Vista)
Product Name:ZoneAlarm Internet Security Suite
