Windows 10: Microsoft defender antivirus will not update.

Microsoft defender antivirus will not update from version 0.0.0.0. System checks for updates but eventually times out.

Defender AntiVirus

There are 4 options under Defender. Two refer to AntiVirus; AntiVirus Network Inspection Service & AntiVirus Services. Under Startup Type these two are listed as manual and the Status column said Inspection Service is running. When I clicked on the Start
button in Properties, I got an immediate message: "Win.. Def.. Anti.. Serv.. on local comp.. started and then stopped. Some services stop automatically if they are not in use by other services or programs."

 

Microsoft Defender VS Microsoft Defender Antivirus?

Today, I uninstalled the Microsoft Defender app on my device.

However, in Windows Security > Virus & threat protection > Security providers, Microsoft Defender Antivirus is listed as my Antivirus.

When I click on "Open app" for Microsoft Defender Antivirus, it just redirects me to Windows Security > Virus & threat protection.

1. Is Microsoft Defender Antivirus different from the Microsoft Defender app?

2. Is my device still being protected?

For context, I do not have any third party antivirus programs installed on my device right now,

and I never signed into the Microsoft Defender app with my Microsoft account,

nor do I have a Microsoft 365 subscription.
