The genuine MpCmdRun.exe file is a software component of Microsoft Malware Protection by Microsoft Corporation. "MpCmdRun.exe" is the Microsoft Malware Protection Command Line Utility. Under administrator privileges, it enables command-line, parameter-controlled invocation of the computer's resident Microsoft antimalware product, (Windows Defender, Microsoft Security Client, or Microsoft Security Essentials). Through scripts or by direct console command prompts, anything from a single file to the entire system can be scanned, with remedial action included or turned off. It resides in "C:\Program Files\<product-name>\MpCmdRun.exe," (sometimes with an additional final subfolder named "Antimalware"), and cannot be removed without uninstalling the entire antimalware product. It has existed from Windows XP up through Windows 10. Some Microsoft documentation suggests that automatic disabling of MSE or Windows Defender real-time protection when third-party antimalware is installed may not prevent MpCmdRun.exe from starting scans. Microsoft Corporation, ranked in 2016 (by revenue) as the world's largest software maker, was founded in April, 1975, by two men, Paul Allen and Bill Gates.

Calls itself "Windows Defender Command Line Utility" is m$ signed and resides in the defender directory. I have no idea though why it is running all the time, never started it, and only recently it was there (maybe after latest vista service pack?) minime
It is not really neseccary and i dont know why it connected every few minutes to the internet: http://www.addictivetips.com/windows-tips/command-line-utility-mpcmdrun-exe-microsoft-security-essentials/ Wolfgang S.
it is :Microsoft Malware Protection Command Line Utility Signed by Microsoft Corporation Bob
This seems to eat up data on my laptop. I can end the process but I need a way to delete it all together. joe garcia
Advare program thaty instals crosbrowse, uc browser, opera browser, bluestacks, snapdo, and more crap. jokbon
This program uploading continuously some sort of data to this address 65.55.252.43:443 without asking, and I am trying to remove it. davoud
It is part of Microsoft Security Essentials, running several times a day allegedly updating MSI. I deleted it, and manually update MSI when I want. Jackyl
it was blocking me from useing taskmanager so i feel its dangerous Classic Toxin
connecting with internet all the time.other than that its fine Sanjid
There is no reason this program should access the web. Defender is not a Cloud Based utility and this does not update the definition _ I have blocked it at the firewall _ in and out. That Command Line Utility can be used to remotely modify your definition to let a bad program run and even turn off your protection_ seems like a back-door to me, so I blocked it. Paul
It duplicate dozens of times in task manager and my computer sudently take 120 minuts to boot...and terribly slow...was formated one week ago DartirAnsi Dova
The IP 65.55.252.43:443 as reported by davoud here, host seems to be msnbot-65-55-252-43.search.msn.com Shaela
Acts as a backdoor in my case. Blocked 2 instances. "Paul" above, is correct that a bad actor or script can cause this "exe" to become malicious & it has turned off parts of Defender without notice. Mack Bolan
go to task scheduler Library-Microsoft-Windows-Windows Defender. DON'T DELETE just disable all scheduled events. But it will still try update Windows Defender Definitions at a random time. You can find log in Temp Folder ~ Run-type temp-OK. in temp folder you will find MpCmdRun txt document, open it will show times it tried to update Windows Defender Definitions. And you might also find in same temp folder UsoStoreFile, they are related like windows update,windows remediation service,windows module installer,windows 10 update facilitation service,windows update orchestrator service quaalude
Don't remove this if you use Windows Defender as your antivirus. MpCmdRun.exe asks for internet access when you check for update of virus patterns. Rumble
I think this kind of software is important to deal with malwares. Should be under Windowd Defender supervision Carlos Manuel

Best practices for resolving MpCmdRun issues
A clean and tidy computer is the key requirement for avoiding problems with MpCmdRun. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.
Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
To get your computer running as fast as it did on day one, you can 8reset your PC. Your personal files will remain intact, but any programs you installed will need to be reinstalled.
To help you analyze the MpCmdRun.exe process on your computer, the following programs have proven to be helpful: ASecurity Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. A good Bantivirus software detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
