Continuous Open process Token

In the last few days In recent history all I ever get every 3 seconds is Unauthorized access  blocked (Open process Token). The follow is listed under view details:

Actor       C:/Program Files/Ask Partner Network/Toolbar/Updater/ TB Notifier.EXE.

Actor       PID 2296

Target     C:/Program Files/Norton /Internet Security/Engine/21.6.0.32/nis.exe.

Target     PID 3784

Action     Open Process Token

Reaction   Unauthorized access blocked

Terminal Session      1

This is all I see in recent history and if I want to check on Live Updates or Scan I have to go to those specific categories. This happened a few years ago but with different targets and actors. After much complaining on the forum by various Forum members, it suddenly stopped. I hope someone can stop it again. it is only happening on the Windows Vista computer and not our XP computer.
