Norton 1 & Norton 360 on computer?

Somehow Norton One and Norton 360 are running on my computer. Can I uninstall Norton One with no ill effects to Norton 360? I have a current subscription and valid for N-360. Years ago I had N-One, but switched to N-360 and am now in my second year with it.  However, every time I start my computer (Window 7), I get a pop-up telling me to complete the N-One installation and also my subscription to it is not current.  I just want to have N-360 running and no need for N-One.  Can I delete that program?  Thanks for any help!
