Insight INSISTS on running!

Searching through the boards, I saw this question asked way back in April of 2010 and nobody answered.  I am having the same problem.  Norton Insight runs EVERY DAY even though I have it turned OFF.  It slows down my computer for between 30 and 60 minutes when it does this and I don't like my system being hijacked like that.

 

When I open Task Manager, ccsvshst.exe is running and I am not allowed to kill the process.  Why does Insight run when it is not supposed to?  I also have my computer set to Full Scan.

 

I don't know if you need to know any specs but I am running Windows XP.  My computer has 3GB of RAM and contains an Intel Dual Core with 2.8Mhz processors.
