Norton or Mcafee what is better? Up date

Have used Norton for years, doesn't slow anything down. If you have more than one computer you want it on, I think you can get a discounts on buying it in groups of three or five. Check out the Amazon pricing and download it with a key they send you after buying it.

If you do have a very old computer and it slows you down, I believe you can set it to do the daily scan sometime during the night, but you'll have to check that. I don't generally turn my computer off.
