Disabling Idle Full System Scan in NIS 2013?

In NIS 2012 and earlier, I disabled idle full system scans.  I just uninstalled and reinstalled 2013 and I can't find the option to disable the idle full system scan in the Norton Tasks options.

 

The only setting for scanning I found is under Computer -> Computer Scan -> Full System Scan.  Is that what I what to change?
