With System Lockdown enabled from the Symantec Endpoint Protection Manager, the Symantec Endpoint Protection client 'Control Log' shows System Lockdown blocked definitions found in a temporary folder. When System Lockdown is in Test Mode and the definitions show blocked, the definitions are still able to process.
Attempting to add the temporary folder(s) to "The following files are approved" section in the System Lockdown settings is not possible because the temporary folders are dynamic.
Examples of definitions being blocked from temporary folder on Windows XP:
C:\Program Files\Common Files\Symantec Shared\VirusDefs\tmp2f8c.tmp\CCERASER.DLL
C:\Program Files\Common Files\Symantec Shared\VirusDefs\tmp5cef.tmp\CCERASER.DLL
C:\Program Files\Common Files\Symantec Shared\VirusDefs\tmp3061.tmp\CCERASER.DLL
Examples of definitions being blocked from temporary folder on Windows 7:
