Need to Configure Norton Security Without Extras

I am having trouble with Norton trying to take over my computer.  All I want is for it to detect security problems and isolate/quarantine the files.  Norton wants me to use their backup (I have one already) and other services.  Right now there is a message that I can't get rid of that wants me to set up a backup.

My friends warned me about this.  That Norton would take over everything and slow the computer.  I want Norton to run a computer scan at 2am and then shut down the computer.  That is all.  How do I get rid of all the other messages?  I am ready to uninstall it!  Very Frustrated, Oldcarfun
