Fix MpCmdRun.exe Issues

Your computer may not run the antimalware command line tool if the MpCmdRun.exe file is malicious. Or if it was accidentally moved from the Windows Defender folder. Windows may also give several error messages if there is a problem with the executable file or if your computer is out of date.

Here are some possible solutions to problems preventing the MpCmdRun.exe command line utility from working properly.

1. Restart your computer

If MpCmdRun.exe is consuming an insane amount of CPU and Internet bandwidth in the background, we recommend turning your computer off and on again. This should update your device and hopefully fix issues causing the tool to malfunction.

2. Scan for viruses or malware

The MpCmdRun.exe file can be a virus even if it is located in the appropriate directory on your computer. Run the file through a third-party antivirus application or online virus scanners. Delete the file from your PC if your security tool marks the file as dangerous or malicious.

3. Run Command Prompt as administrator

The Anti-Malware Command Line Utility may fail to perform certain operations if the command line does not have sufficient privileges. Whenever you need to use the common line tool MpCmdRun.exe, make sure you run the command line version at the administrator level.

4. Update your computer

If you receive the error code “0x80070667” when you run the MpCmdRun.exe command, it is because your computer is running an older version of Windows 10. For optimal performance, make sure your computer is running Windows 10, version 1703 (or later).

Go to Settings> Update & Security> Windows Update to check for available updates.

Security Intelligence updates for Microsoft Defender Antivirus are also installed along with Windows updates to help protect your computer from the latest threats.

Connect your computer to the Internet, run Command Prompt as administrator, type the command below in a terminal and press Enter.
