I do use the Premium version these days. I upgraded this year. I also came to realize that with all my demands and security concerns I needed a new PC and picked one up with a strong CPU, plenty of memory and storage. Both security programs, Norton and Malwarebytes, have worked very well together with Windows 7. Malwarebytes was even compatible with Windows 10. It survived the downloading of the new operating system into the PC on Friday while the other program disappeared. I later learned that Microsoft had included Defender with Windows 10 while Norton customers were obliged to wait for an upgrade of their app on Sunday that could be used with 10. A lot of software firms had problems with the new operating system. I was really surprised. Another management took pride in the compatibility of Windows and how backward looking it was. Guess those days are gone.
