Turn off Norton advertising ("education")?

I purchased Norton 360 Premier. Nonetheless, after having paid for the whole enchilada, I must still suffer through Norton popups that are essentially advertising ("The new version of Norton will have great new features...Save for Later/Learn More"). Some ads do have a "Don't show again" link, but it doesn't work! 

  1. How can I turn such advertising off, but still receive actual security-related popups?
  2. If this is not possible, can someone suggest an antivirus product that does not advertise itself after purchase?

Many thanks.
