Windows 10 has completely trashed my Norton Internet Security. I would like to know how I can re-install it. I do not have a CD because I renewed online. Can you please advise.
Please go to your Norton Account. There you will find a download button for your NIS.. You can also use this link. www.norton.com/latestnis Please run Live Update a few times until it says no more updates and then restart.
While you are at it, you can also turn off Fast Startup.
