Ccsvchst.exe still on after using removal tool

Hello

I have been trying to remove Norton Antivirus for some time now due to it's high resource usage which cripples my PC. I have only a single core processor & Norton was using up to 35% (extreme fluctuation spikes) of the cpu at idle with live protect turned off & quiet mode on.

This is completely unacceptable to me so I've run the Norton removal tool twice and yet ccsvchst.exe is still running. I am the only user of my computer and yet I cannot shut off of disable the Norton Identity Safe service which denies me access.

How can I remove ccsvchst.exe / Norton identity safe service once and for all? Thanks.
