Nothing wrong with Norton, Kaspersky, or Nod32. They've all been around for a while and have good reputations. In fact, depending on which antivirus review forum you look, they've all been rated "best" at one time or another. So my only suggestion is try to get a free 30 day trial, use each one, and see which one you like best.
One caution: make sure you completely uninstall one product before you install another. That might require you to use an official uninstaller made by teh company itself - not just using control panel > programs and features. Here's a list of product uninstallers as provided by Microsoft. Each vendor may change the uninstaller at any time so it's always a good idea to check the vendor's website and search for "uninstall tool".
