Norton Security's Default settings don't include Full System Scan?

When my 360 subscription expired, I replaced it with Norton Security. I was under the impression all of my settings would be saved--OR that even if they weren't, the Default settings would cover most "basic" tasks. I guess I've been lax about reviewing my Norton History, but I just discovered that the newer product hasn't performed a single Full System Scan since installed 5 months ago!  Surely such a fundamental task doesn't have to be "custom"-configured, in other words the Default Settings should call for it to be performed automatically from time to time, no?? And if not, what other basic tasks has the newer product not been performing because I haven't told it to?!
