Either uninstall the MS updates KB951748 and KB951698 (in the Control Panel's Add and Remove Programs and check the "Show updates" box) or set the ZA's Internet Security slider to Medium<hr>
It is more secure to use the Internet Security slider at the High level not at the Medium level.
Or use the High and create specific rules will work as well with the latest MS updates.
If you wish to retain the MS updates and use the Internet Security slider at High (the default and correct setting), then do an uninstall of the ZA, after the required re-boot then manually remove the files found inside of these folders:
[*]WINDOWS\ Internet Logs folder[*]Program Files\Zone Labs folder[*]WINDOWS\system32\ Zonelabs folder[*] any files in the Windows\Temp folder[*] and any files found in the Temp folders found in the Document and Settings[*]empty the Recycle Bin
Then re-install the ZA.
This method has been successful with the older ZA 5.5.094.000 and with the latest MS updated all installed, on a windows xp he sp3.
