Backup Norton 360 App is aggressive on laptop processor

A general comment I am making here is about the manner of intermittent interruption to my
computer routine, coming from the Backup app/component of the Norton 360 suite.
A higher pitched whining whirr is audible when contankerous Mr/s Norton Back Up
comes 'round pushing its weight.
I'm not much of a fan of cloud storage. I prefer to use my own portable drives.
It is suggested maybe we could be simply given an option to choose back up as an added extra (free of course)
along with the other components of the Norton 360 subscription. But no. No happy endings while we are stuck with 
a para-psycological glitch in the form of an app within the Norton 360 app that can basically close down the whole suite of 
other security functions simply because we are busy with something and are not going to JUMP when Back-up says jump.
The Backup app in Norton 360 has inbuilt shutdown capability, that it will randomly attack subscribers computers with.
I find it hard to believe that Norton software corporation thinks this is totally okay to let ride.
I don't. If anyone else agrees. Please do add your comments.
