Defender Antivirus - how to solve these errors?

Hello community,

The message „service not running“ and „signature updates out of date“ - can anyone explain this to me and how we can solve this?

We force signature updates within the policy so I am not sure why this is happening.

Thanks

Cheers,
John

    If Microsoft Defender Antivirus did not download protection updates for a specified period, you can set it up to automatically check and download the latest update at the next log on. Refer the article - https://docs.microsoft.com/en-us/microsoft-365/security/defender-endpoint/manage-outdated-endpoints-microsoft-defender-antivirus?view=o365-worldwide#set-up-catch-up-protection-updates-for-endpoints-that-havent-updated-for-a-while
