What Kind Of Process Is Msmpeng.Exe And Why It Loads The Processor? 3 Easy Ways To Disable It

Sometimes a PC or laptop starts to slow down and freeze, and the Task Manager displays the MsMpEng.exe process, which consumes a lot of resources. What happens and how to fix the problem, we will tell you further.

What is the process MsMpEng.exe

msmpeng.exe

MsMpEng.exe belongs to the standard “Windows Defender,” which by default replaces the antivirus, which nevertheless does not prevent malware from penetrating this computer.

Often it is this which causes the failure of work. MsMpEng.exe checks how safe the programs that are started and the downloaded files are, and from time to time, it scans whether the virus has settled in the hard drives.

Sometimes, however, the process is launched by mistake due to a conflict with the antivirus and prevents normal use of the computer. Now we have found out that this, with rare exceptions, this process is useful and important. Why is he so immoderate in the use of resources?

Why MsMpEng loads the processor

MsMpEng.exe, if it is started in the standard way, without errors, loads the processor in the following cases:

  • when you left the computer for a long time in standby mode;
  • at the time when you unzip something;
  • Upon turning on the computer (especially in Windows 10 );
  • when the program starts for the first time or after a long time.

If nothing like this happened, and the computer system still slows down due to the MsMpEng process, then something went wrong.

To find out the reason, try the following:

Turn on the computer and open the Task Manager. Find there MsMpEng.exe, remember or write down how much resources it spends.

After that, reboot, call the Dispatcher again and verify the figures. If the process gradually reduced consumption, click “Search” (next to the “Start” button) and enter “Control Panel”, then change the view mode to “Large icons”, open the “Power Options” section – “Power buttons action” and remove the check mark from the “Quick Start” item.

This can immediately solve the problem.

Update your antivirus to the latest version (it is the package itself, and not just the database, it will not affect the acquired license) and check whether the normal operation of the system has been restored.

  1. Scan your PC for viruses with the help of some reliable utility.
  2. Click Win + R, in the appeared window write: “cmd” without quotes and “Run.” Type “chkdsk C: / F / R” into the black box and click Enter. The system will check if there are any errors on the hard disk and correct them themselves.

If all this does not lead to anything, you just need to interrupt the process MsMpEng.exe.
