Method #4: Repair Corrupt Defender files

Sometimes the internal files get damaged or are corrupted due to some virus. You can always download Reimage Plus to look for those corrupted files and repair them. If still the CPU usage is getting high, switch to #1.

Method #5: Scan for Malware

There is a slight possibility that malware might have attacked your MsMp.exe, leading to a prolonged lag. If you find any of these possibilities, I would recommend you to do a manual scan of Windows Defender itself. You can use various anti-malware softwares like Adwcleaner and Malwarebytes. These applications would delete any malware that was hindering your system.

Method #6: Disable Windows Defender

The most effective way is to remove the Windows Defender. You can easily disable it from your PC, and therefore no space be consumed for the scan.

Steps:

  1. Press Windows Key + R (Run Dialog Box)
  2. Then, type regedit and click OK to open the Registry Editorregedit
  3. Search for HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender in the folders
  4. Finally, find the registry with name Disable Antispyware and set its value to 1

    Change Value of DisableAntiSpyware to 1
    Change Value of DisableAntiSpyware to 1

But make sure after disabling it, your PC becomes highly vulnerable to cyberattacks. Make sure to install antivirus software prior to these steps.

Method #7: Latest Window Updates

Windows Defender can also treat any newly installed file as a virus. It will try to neutralize the file using various techniques. This will definitely affect your system speed and might occasionally freeze. Try to re-install any new applications that might be causing trouble.

Method #8: Upgrade Applications

This situation is vice-versa of #6. As above stated, MxMp.exe needs to conduct a full system scan to run a diagnosis. If an application is not updated as per the latest version, it might get sorted out in the scan. Make sure to keep all your everything up to date.

Method #9: Apply for Real-Time Protection

To avoid the complete stress on the Windows Defender, install a secondary application that will provide real-time protection to your PC. It will relieve pressure on a single software like MsMp.exe and won’t affect the performance of your system.

Method #10: Install Latest Version

Windows Defender gets its updated version regularly. Don’t hesitate to spend some of your data to upgrade it. The newer versions will provide better protection and will be faster than their predecessors. 

Method #11: Locate Malware Infections 

The scanning process can make your computer not work as per its full capacity. The primary reason is the malware attack. Don’t forget to run a full system scan to kill the viruses using a reliable solution like Avast antivirus software.
