As you can see this is why you should test out different software to find out what is best for your scenario.
Norton is a decent product but I have had problems using it. It is, like every other software product in the world, not perfect.
By posting here you are getting opinions, which is great, but no substitute for testing. Maybe Norton will run brilliantly on your system and cause you no problems or maybe the opposite will true.
All i can say is test before you go live.
