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.

Please update Malwarebytes; this issue was corrected in the most recent release published yesterday:

To update, open Malwarebytes and click the small gear icon in the upper right to access settings, then click the Check for updates button located near the top of the General tab and allow Malwarebytes to download and install the update.

Once that is done, restart your system to ensure the new components are loaded into memory, and clear your browser cache and DNS cache if your web searches are still unreachable.

Please let us know if that resolved the issue or not.

It's likely that Firefox uses the default loopback address for some purpose, or perhaps an extension installed in Firefox does.  Also, if you use a HOSTS file for blocking content on the web, it is likely configured to redirect blocked sites to

Yeah it happened with everything i did with firefox even opening ublock origin or browser guard, but it started when i was on mega.nz trying to watch a media file, but it never happened before so i was worried because i don't even know what is and i thought i messed up with something bad

It's probably due to one of the plugins/extensions then, or it could even be due to Firefox's build in privacy functions as it may redirect blocked content to, though that's just speculation on my part.

It started when i went to try and test my ip protection with iptest web and then i went watch some media file on mega.nz and on my ublock origin control panel i have this, then after the iptest block warning i get that ip blocking warning with every single thing i tried to do with firefox. I don't know what that IP is, i've read something about localhost but im worried it was some kind of malware but nothing on my MB scan

Yes,, also known as the loopback address, is an IP that points back to your own machine.  It is definitely not malware, so no worries on that front at least.

Here's an explanation of what the loopback address is and a brief description of its purpose: https://www.webopedia.com/definitions/loopback-address/

Ok, thank you so much for your help

@exile360 I think i've found what started my issue. At first I went to try my web protection going to vidto.me because i know mb and browser guard blocks it and on my report its Ip shows as

I know the website is down since a long time ago because on VT its status is 404 and on its details shows as its IP so maybe that's what started the loop, that and the mega.nz media file website witch also have that IP

It's likely something about how Firefox connects.  It likely connects to the loopback address for some reason, like perhaps to establish or check network connectivity or something similar, and with the loopback address being blocked, it was unreachable which caused Firefox to bug out/fail to launch.
