Windows Defender is disabled in Windows 10 startup. I did not disable it. Did Norton 360 disable it, possibly when I installed Norton 360?
.
any 3rd party antivirus ( security ) will pause or disable the defender, thats built in to be compatable windows
just means in generic terms that defender isnt going to run or interfere with any other antivirus program
Windows Defender is automatically disabled once you install Norton on your computer.

We do not recommend enabling Microsoft Defender's periodic scanning feature on a Windows 11/10 system having Norton protection.
