I've had Norton for years, when I signed up this year, I was surprised to see that they took over my Chrome QUICK START opening page selections and inserted (Ads) like "Nordstroms" and 5 other companies I have never visited even once.I tried to delete their  names in Extensions but quickly found they are not listed in my chrome extensions as a separate identity, apparently I am not able to monitor or manage how much power they have reading and recording my activities. 

Google had the right idea when they allowed us to actually list sites we visit frequently. Since I am a paying customer,  I would expect Norton to offer the same courtesy.  

If this truly can't be changed and bothers other readers, please let Norton know.
