Windows 10, Spyware and unwanted software protection...

Hello everyone! I have this question:

I disabled Windows Defender by changing the registry key, creating a DWORD value that says DisableAntiSpyware, then I used the Norton Removal & Reinstall tool and everything went better but yesterday I noticed that if I go to Control Panel > System and Security > Security and Maintenance it says:

Network Firewall         On, Virus protection       On

And next should say "Spyware and unwanted software protection" but it doesn't appear! My Norton product says everything is fine. On Windows 8.1 I remember I didn't have any problems and also remember this thing about the Spyware and unwanted software protection being ON. My PC is protected? How this disappear? I disabled Windows Defender with regedit.exe because it was trying to keep active no matter I upgraded from Windows 8.1 with Norton.

Thanks in advance for your help...
