Windows 10: Windows Defender Antivirus not Updating

Windows Defender Antivirus is not getting update and showing message of Virus and Spyware Definitions could not be installed.

Please Provide me Suggestion.

:)

 

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."

 

definition update for windows denfender antivirus


Hi mknic,
I have literally just installed the definition update KB2267602 without any problem. I suggest as a first step checking all the Windows Defender settings to make sure they all have the 'green ticks' in each section.






ps. The only reason the 'Family Options' is not ticked is because I am the only user on my computer.

I also would suggest running the 'Troubleshoot' feature in the Update & Security settings which has a section dealing with update problems.

 

Windows Defender - antivirus?

Windows defender is a built in antivirus, that detects all type of threats.You do not need to install any 3rd party antivirus.

In windows 7 and earlier Microsoft security essentials was to be used with windows defender for a full system protection, but in Windows 8 and later windows defender's capabilities have been increased to make it a full fledged antivirus.

I suggest rolling with Windows Defender (preinstalled)+Malwarebytes for a full system security.
