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.

Hi Porthos, those pending operations may have been from from my trouble shooting the problem. It also failed on a second Windows 11 machine I use for automated testing. That was where I first encountered the problem when the tests all failed because it couldn't display Chrome. I had to quite Malwarebytes to allow the test suite to run.

Hi codesmithery,

Thanks for posting. Like you mentioned this issue is being reported to us since today's windows update, we are looking into it.

As a workaround, there are a couple of options that have internally worked for us

1. Try setting Chrome as a default browser


2. Turn off Chrome as a protected application in the Malwarebytes product. you can find this in Settings->Security tab

Hi Porthos, I tried rebooting, it didn't resolve the issue.

That is ok. Staff responded with a workaround. I have Windows 10 and have no current issues with Chrome. Seems to be an 11 issue.

Turning off "exploit protection" allows Chrome to open for me. I also did the windows update this morning and am running the Beta Update package 1.0.70831 Component package 1.0.939

Following Arthi's instructions also works and is probably a better way to do it.

It seems that in 2018 Chrome was removed from MB exploit protection at Google's request but evidently put back in at some later date. See this MB article... https://support.malwarebytes.com/hc/en-us/articles/360039018713-Chrome-removed-from-Anti-Exploit-list-of-Protected-Apps-in-Malwarebytes

Unless this is referring to something different.???

There are two options available other than disabling the Exploit Protection layer completely. Please see Arthi's earlier post


Of course, indeed I've already put them in practice, but these are just workarounds.

What I wanted to know was: will there be a real fix for this issue?

I hope a patch is pushed out by Malwarebytes as soon as possible, our phones have been ringing off the hook all morning with customers calling about not being able to open Google Chrome which is a pretty big problem (considering it's one of the most important apps that a lot of people use because all their passwords and bookmarks are saved within).
