Setting up a full system scan NIS 2012

Vista home premium 32 bit
NIS 2012

Ok on my PC I have two accounts
Admin account with full rights
Limited user account where for example I need to put in the admin code if I try to install someting.

So when logged in as the limited user, when I go to the NIS user panel I can’t make very many changes to Norton. That makes sense.

But if I go to
Norton panel> scan now> custom scan
I can go to the scheduled full system scan and hit the edit button. I can then change the time and frequency of the scan and some of the scan specifics.

Should I be able to do that as a limited user? I would think that I should NOT. : (
