In this article, I’ll show how to stop the Windows Defender Antimalware Service Executable to hit 100% and slow your server completely.
Recently, I’ve worked on a File Server Migration project between Windows Server 2008 R2 and Windows Server 2016 File Server.
While copying the Users file across to the new Windows Server 2016 server using Robocopy I’ve noticed that the Antimalware process Is scanning each copied file and a 40GB file transfer Is taking more than 24Hours.
After doing a bit of research I found that there are two fixes to this Issue:
- Stop the Windows Defender real time scanning, Which didn’t help In my case and I had to move to option two
- Uninstall Windows Defender
To stop the Real Time Scanning option open PowerShell as Admin and run the cmdlet below:
Set-MpPreference -DisableRealtimeMonitoring $true
It that doesn’t help, Uninstalling Windows Defender using the cmdlet below
Get-WindowsFeature *defender* | Remove-WindowsFeature
When done, Restart the Server

This is the only fix that worked. Thanks
