NIS 2010 - Insight Optimizer keeps turning itself on

 Running NIS 2010 clean install on Vista HP.

 

I've got Insight Optimizer turned off in NIS settings.

 

I've got Windows Defragmenter turned off in Scheduled Tasks

 

I cancelled Insight Optimizer in Norton Tasks.

 

Yet I keep gettting the pop-up "Norton Internet Security is currently performing background tasks" and when I check Norton Tasks, Insight Optimizer is running again EVEN THOUGH in Settings it is still shown as switched "Off".  Note

 

How do I permamently kill this process?  I have Perfect Disk and I prefer to use that program.
