Why Is Malwarebytes Using WmiPrvSE? It Makes My Laptop Run HOT and High CPU

Recommended Posts

For years my laptop ran at 47C with previous versions of Malwarebytes running.

Now, with the latest Malwarebytes version (don't ask me when it changed - I didn't notice) the laptop is running at 77C.

This is because my laptop is running a process called WmiPrvSE which is using 15% CPU continuously.

When I try to stop WmiPrvSE it says it cannot be stopped because Malwarebytes is using this Windows process.

So I just stopped Malwarebytes and WmiPrvSE is now using negligible CPU and the CPU is now 47C.


So, Malwarebytes techies, please explain:

1.  Why are you using WmiPrvSE?

2.  Why can't you gather whatever data is being provided to you by WmiPrvSE some other way?

3.  If you MUST used WmiPrvSE, why can't you access it less often?

4. Was this version of Malwarebytes tested on Windows 10 laptops?


I'm close to cancelling my contract for this laptop if you can't fix this problem.

Hello @RogerPhuket

The WMI service is used by almost every program on a computer. It is an integral part of Windows.

Let me get some logs please and we'll see if we can track down what is really going on.


To begin, please do the following so that we may take a closer look at your installation for troubleshooting:

NOTE: The tools and the information obtained are safe and not harmful to your privacy or your computer, please allow the programs to run if blocked by your system.

  • Download the Malwarebytes Support Tool
  • In your Downloads folder, open the mb-support-x.x.x.xxx.exe file
  • In the User Account Control pop-up window, click Yes to continue the installation
  • Run the MBST Support Tool
  • In the left navigation pane of the Malwarebytes Support Tool, click Advanced
  • In the Advanced Options, click Gather Logs. A status diagram displays the tool is Getting logs from your machine
  • A zip file named mbst-grab-results.zip will be saved to your desktop, please upload that file on your next reply

Thank you

Well, this is weird. I stopped Malwarebytes (MB) running about a week ago because of the overheating and the 15% WmiPrvSE process CPU usage that was being caused by Malwarebytes. Today I started MB and ticked the four protection boxes and the CPU temperature settled down to less than 50C and the CPU usage was a bout 3% (DWM.exe) - no WmiPrvSE usage.

So, to be sure this was "normal", I restarted the laptop and the temp. is still below 50C and CPU is 2% (again Dwm.exe), i.e. no more WmiPrvSE usage.

I even ran Skype which is the main reason I needed this problem fixed as the overloaded CPU caused stuttering on the sound and video. It ran OK.

So I'm thinking now that something in Windows or Malwarebytes got mixed up and by turning off Malwarebytes and back on again appears to have fixed it, and it has stayed fixed even after a restart of Windows.

The alternative (conspiracy) theory is that you secretly updated it while I wasn't running it and now it's fixed!


A couple of observations:

on my Windows 10 desktop, Malwarebytes (Premium) reports its version as 4.4.6. The Mbam.exe file version is

on this Windows 10 laptop, Malwarebytes (Premium) reports its version as 4.4.0. The Mbam.exe file version is
