Malwarebytes causing heavy problems in DCS game for PC - Confirmed Problem!

Recommended Posts

Hey guys,

I just want to let you know that the current version of Malwarebytes is causing stutters (frametime peaks / microstuttering) in some games especially DCS (https://store.steampowered.com/app/223750). It is a known problem. I just read it in the community discussions where someone else mentioned it and I also had massive issues with that some days ago.


It appers that Malwarebytes somehow interacts with the game-window or something and causes these micro-freezes.


Please fix this.

The current way to play this game is to completely close and disable Malwarebytes.


Thank you, cheers!

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.

Well I don't think its a protection issue. I could add it to whitelist but that won't solve the problem.


And why should I add logs when it's definitively a Malwarebytes problem.

I sent you the link to the Steam forum where other people also complained about the problem.

So the developers should probably instead install DCS (free to play) for themselves and check whats messed up with their own software.

I just checked the first post in the steam forum thread which indicates that disabling Ransomware Protection alone appears to resolve the issue with performance, is this consistent for you as well?  If we can determine precisely which individual component is causing the problem that should greatly aid the Developers in tracking down the cause of the issue in the code and correcting it more quickly.

Additionally, please do the following so that they may also have a better understanding of your environment and installation:

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

By the way, I will also be reporting the Steam forum thread to the Product team in case they were unaware of it and I would encourage anyone affected by this or any similar issues to please create a new topic in this area of the Malwarebytes forums so that they might provide details of the problems they are experiencing to further aid in documenting the issues and hopefully more quickly achieve a resolution.

Have not tested yet what happens when I disable the ransomeware protection.

And I also have not tested what happens when I whitelist DCS.

But I found this Malwarebytes Tray Application which appears when I press ALT+TAB during the game.

Malwarebytes is closed to tray at this moment and it is not minimezed but it still appears in ALT+TAB.

This is probably causing the issue!

All documentation indicates that the Alt+Tab problem was an issue fixed long ago in a much earlier release.  This support article shows the details.

Please try a clean install to see if it corrects the issues you're seeing:

  1. Download and run the Malwarebytes Support Tool
  2. Accept the EULA and click Advanced tab on the left (not Start Repair)
  3. Click the Clean button, and allow it to restart your system and then reinstall Malwarebytes, either by allowing the tool to do so when it offers to on restart, or by downloading and installing the latest version from here

Please let us know how it goes and if the issue is resolved or not.

OK, please run the following tool so that we may check the status of your installation and components and hopefully discover the cause:

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

Just because some have the issue not all will. The logs tell us a lot more on your setup so we can not only fix it for you but it lead to a fix for others.

Our developers could do as you said install and test but might not have the same issue on the test computer. Every computer hardware, software etc. is different.
