The Malwarebytes Support Tool can run without an Internet connection. When you run the Malwarebytes Support Tool offline, the tool creates troubleshooting logs and saves them to your Desktop without uploading them to Malwarebytes Support. 


  1. Download the Malwarebytes Support Tool.

  2. Locate the downloaded file mb-support-x.x.x.xxx.exe.
    Downloaded files are usually saved to the Downloads folder.

  3. To open the Malwarebytes Support Tool, double-click the downloaded file mb-support-x.x.x.xxx.exe.
    When the Malwarebytes Support Tool opens, the application automatically downloads the latest updates.

  6. The Advanced menu page contains four options:

    • Gather Logs: Collects troubleshooting information from the computer using Check and Grab functionality. As part of the process, Farbar Recovery Scan Tool (FRST) also runs a complete diagnosis of the computer. The troubleshooting information is saved to a file on the Desktop named mbst-grab-results.zip. This file can be added as an email attachment or uploaded to a forum post to assist your Malwarebytes Support agent in troubleshooting the issue.
    • Clean: Performs an automated uninstallation of all Malwarebytes products installed on the computer and prompts to install the latest version of Malwarebytes afterwards. The Premium license key is backed up and reinstated. All user configurations and other data are removed. This process requires a computer reboot.
    • Repair System: Restores Windows services back to the default state. Check the desired options and click the repair system button. Use this option only if recommended by Malwarebytes Support.
    • Anonymously help the community by providing usage and threat statistics: Unchecking this option prevents the Malwarebytes Support Tool from sending anonymous telemetry data on usage of the program.


  7. Click Gather Logs.
