M365 Defender ATP - manual run antivirus scan for a device starts very slow

Hi Everyone,

 

I have the problem that when I want to manually start an antivirus scan over the Microsoft Defender Security Center on a specific device, it takes a very long time (sometimes up to one hour) before the scanjob really starts.

 

Does anyone have an idea what I can do to make the scan start immediately on the client when I start the scan job?

 

Thanks in advance

 

Kind Regards
Marvin Peters

  • mpeters_all41 If you deploy via Endpoint Manager you could set a script to kick start a scan, the PowerShell is Start-MpScan, or you could run that command on the local box. The is going to be a delay when an agent is installed, an inventory is running against the box as well as a vulnerability assessment.
