After updating a Symantec Endpoint Protection client on Windows 2000 to the definitions dated August 19, 2013, revision 17 or later, while shutting down the computer, a blue screen error occurs.

One of the following errors may occur when shutting down

"STOP: c0000263 Unknown Hard Error"

"STOP: c0000263 {Driver Entry Point Not Found}

The \??\C:\Program Files\Common Files\Symantec Shared\EENGINE\EraserUtilRebootDrv.sys device driver could not locate the entry point PsGetContextThread in driver ntoskrnlexe."

After restarting the computer, the following error message appears in the Windows Event Viewer:

"EraserUtilDrv 11310.sys device driver could not locate the entry point PsGetContextThread in driver driver ntoskrnl.exe"

This problem is related to the ERASER engine update in the August 19 rev. 17 definitions update. The update incremented the ERASER Engine file version to 113.1.0.101 or later for ccEraser.dll and .sys files.

Symantec has rolled back the Eraser engine that causes this issue. The definitions that contain the rollback are dated 20 August 2013, revision 19, sequence number 146721. Symantec recommends that you update your virus definitions to this version or later.
