Blue blank screen when system shutdown

Hi all,

I am sorry for duplicate threads, but first thread is in solved status and it's not correct.

First thread is: https://www-secure.symantec.com/connect/forums/blue-blank-screen-when-system-shutdown.

We performed upgrade of Symantec Endpoint Protection to RU4 version. Frequency of problems is smaller, but problem with shutdown and freezing of programs is still here.

We tested cleaning with CleanWipe, but without solution.

Does anyone know a solution of this problem?

Thanks...
