Norton Internet Security Need Help

I just got a new computer yesterday- HP Spectre x360. Present from Hubby.  I have had Norton protection since forever. Currently on this new one just have Windows Defender (think that is what it is called) It was on this computer when I got it.   Norton was on my last laptop (believe it was  Windows 7 pro). Then I became one of the millions that Microsoft forced to update to Win10 when I didn't want it and never was given option to decline the update, just automatically updated after multi days of refusing to do so.. Last version of Norton I bought at a store was Norton Internet Security 2007 XP Home/XP Pro (cd) for up to 3 PCs. Didn't need for 3 pcs but was only thing they had. Has been automatically updated every year. Including after the forced update to Win 10.  Issue I am having is: I tried loading it onto this PC using the disc. wouldn't let me said I needed XP. So where do I need to go to get the latest and greatest of that I have on by old laptop? Sorry so long but not major tech savy person but wanted to give as much info as I could.   If someone can point me to the correct page I can download it from would really appreciate it.

Thanks, cynthia
