My context menu shows the Norton Internet Security entry just like your second screenshot does.
Have you tried uninstalling, and then running the Norton Removal Tool, before reinstalling the new version?
Not sure if it would fix your issue, but that's what I'd try.
**Edit to warn that should you decide to use the Norton Removal Tool, to the best of my recollection, when run, it will remove/uninstall "ALL" Symantec products from your computer (it warns you about this). It can't be set to only uninstall a specific product.
**2nd edit: In case this post on the Norton Forums is related to your issue...
