I havw been using norton security for years and currently I am using on my phone as well.a paid version charge nearly Rs 500. Yet the services is not upto satisfaction. They always require us to turn our location on . Web protection always turns off by itself. Come on.its a paid version .we can't keep on looking on to that. After all there is no proper scaning of anti virus but it keeps on scanning my phone almost everytime and their app makes me look for minutes to see what I am looking for. complicated apps.
