ScriptScan whitelisting fails and URLs visited are not logged in the debug output index file

Environment

McAfee VirusScan Enterprise 8.7i with Patch 1
 

Problem 1

Scripts that are whitelisted are still scanned by ScriptScan.

Problem 2

If ScriptScan debug output is enabled in the registry, the output index file called index fails to record the URLs visited for all scripts regardless of whitelisting.

Cause

The @="scriptproxy" value is missing from the registry key:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objects\{7DB2D5A0-7241-4E79-B68D-6309F01C5231}]

This can be caused by third party malware or spyware scanners, group policies, or manual deletion.

Solution

CAUTION: This article contains information about opening or modifying the registry.
  • The following information is intended for System Administrators. Registry modifications are irreversible and could cause system failure if done incorrectly.
  • Before proceeding, McAfee strongly recommends backing up your registry and understanding the restore process. For more information, see: http://support.microsoft.com/kb/256986.

  3. Right-click the key and select Export.
  4. Name the file scriptproxyBHO.reg and save it to a (shared) location which can be accessed from the affected computer.
  5. Close the registry editor.
     
Step 2 - Export the value needed to the affected computer:
  1. Copy scriptproxyBHO.reg from the (shared) location to affected computer.
