Are you sure that you really want Norton at all?!
Among the premium products, it doesn't have a leg to stand on - slow definition response, large system footprint, not the most thorough cleaner - and it gets beaten by the free products as well.
If you want to pay; get either F-Secure Suite or NOD32 plus Outpost.
If you want to save some cash; use AVG or Avast coupled with Kerio.
