Emails on renewing

How do I stop getting emails on renewing my NAV 2012. I do not like being online without an anti-virus even if it is to download one if I need to redo it. It seems one area of Norton doesn't know what the other is doing. You might think by me regestering my prodict that would be enough to let you you know I HAVE renewed the product. So please stop with the emails NORTON!!!!!!
