Norton and Spy Sweeper Question

[KayfabeMan]

I have both of these programs installed on my computer, and both have recently expired it says. It offers me to renew subscriptions to both of them, Norton internet security and Spy Sweeper.

I am wondering [because I'm clueless to all this], should I / do I need to renew subscriptions with both of these programs, or just one, and if just one of them, which one am I better off with???

Any help would be fantastic.
