Definition updates add entries to "PendingFileRenameOperations" registry key on a frequent basis

On a regular basis, virus definition files for Symantec Endpoint Protection are added to the "PendingFileRenameOperations" registry key.  Is this expected behavior?

Registry key: HKLM\SYSTEM\ControlSet001\Control\Session Manager\PendingFileRenameOperations

Key's value data: \??\C:\ProgramData\Symantec\Symantec Endpoint Protection\12.1.1000.157.105\Data\Definitions\IPSDefs\20120131.002\IDSxpx86.dll

Definition files are being replaced; old definition files are not removed until after reboot.

The issue has been fixed in SEP 12.1 RU2.
