Mapwarebytes slowed my computer way down

Recommended Posts

I'm new to Malwarebytes. It's been running okay the last few days but today my computer Win10 started running extremely slow. I shut MB down and my computer was back up to speed. Tried to start MB again and received a message "couldn't connect to the service". Is there anyway to fix the issue?

Thanks for posting in the Malwarebytes for Windows Help forum.

If you are having technical issues with our Windows product, please do the following:

Malwarebytes Support Tool - Advanced Options

This feature is designed for the following reasons:

  • For use when you are on the forums and need to provide logs for assistance
  • For use when you don't need or want to create a ticket with Malwarebytes
  • For use when you want to perform local troubleshooting on your own

How to use the Advanced Options:

  1. Download Malwarebytes Support Tool
  2. Double-click mb-support-X.X.X.XXXX.exe to run the program
    • You may be prompted by User Account Control (UAC) to allow changes to be made to your computer. Click Yes to consent.
  3. Place a checkmark next to Accept License Agreement and click Next
  4. Navigate to the Advanced tab
  5. The Advanced menu page contains four categories:
    • Gather Logs: Collects troubleshooting information from the computer. As part of this process, Farbar Recovery Scan Tool (FRST) is run to perform a complete diagnosis. The information is saved to a file on the Desktop named mbst-grab-results.zip and can be added as an email attachment or uploaded to a forum post to assist with troubleshooting the issue at hand.
    • Clean: Performs an automated uninstallation of all Malwarebytes products installed to the computer and prompts to install the latest version of Malwarebytes for Windows afterwards. The Premium license key is backed up and reinstated. All user configurations and other data are removed. This process requires a reboot.
    •  Repair System: Includes various system-related repairs in case a Windows service is not functioning correctly that Malwarebytes for Windows is dependent on. It is not recommended to use any Repair System options unless instructed by a Malwarebytes Support agent.
    • Anonymously help the community by providing usage and threat statistics: Unchecking this option will prevent Malwarebytes Support Tool from sending anonymous telemetry data on usage of the program.
  6. To provide logs for review click the Gather Logs button
  7. Upon completion, click OK
  8. A file named mbst-grab-results.zip will be saved to your Desktop
  9. Please attach the file in your next reply.
  10. To uninstall all Malwarebytes Products, click the Clean button.
  11. Click the Yes button to proceed. 
  12. Save all your work and click OK when you are ready to reboot.
  13. After the reboot, you will have the option to re-install the latest version of Malwarebytes for Windows.
  14. Select Yes to install Malwarebytes.
  15. Malwarebytes for Windows will open once the installation completes successfully.

Can you please collect and upload as an attachment the diagnostic data using our MBST?

  • Download and run the Malwarebytes Support Tool
  • Accept the EULA and click Advanced tab on the left (not Start Repair)
  • Click the Gather Logs button, and once it completes, attach the zip file it creates on your desktop to your next reply

MB is doing it's daily scan, has been scanning for over an hour and still running. Should I cancel the scan and run the MB Support tool?


Restart the computer and this time get me the log as requested on Christmas, DO NOT try any repair yourself.

Here's the zip file. 


I  highly suggest turning off fast startup in Windows. Then restart.


Next, You need to adjust the scan scheduled time to a time of day where the computer is on and you are not needing it.

Personally I have not run a scheduled scan in a long time. I do them manually once a week and do not do any thing else until the scan is over.

How long does a manual standard threat scan take on your computer?

I turned off fast start up and rebooted. The manual threat scan took 41+ minutes. 

That seems a little long. Were you using the computer for anything else during the scan?

Your log shows rootkit scanning on. It is not needed and slows the scan down. I would turn it off.

So I don't need to scan for rootkits?

Not on any regular basis. Just when you think you are having an infection issue.

I had my browser open during the scan. My whole system is running slowly. 

During a manual scan, Malwarebytes uses 100% of your resources. It is best to not use the computer at all during a scan.

Do another scan without rootkit scanning enabled and no programs or browsers open and see how long it takes.
