When I signed up for my MS Windows update, I obtained a notification that the version of Norton Antivirus that was on my computer was not suitable with MS Windows 10. I thought nothing of it and modified it. After upgrading, I obtained the notification once again and again, downloaded the Norton software. Compared the time I downloaded it with MS Windows 8.1, I obtained a window saying that my Norton had expired and I needed to renew it.
