TDR and Malwarebytes

Deployment Overview

Threat Detection and Response (TDR) is a collection of advanced malware defense tools that correlate threat indicators from Fireboxes and Host Sensors to enable real-time, automated response to stop known, unknown, and evasive threats.

As part of the TDR solution, you install TDR Host Sensors to provide endpoint protection.

This document includes information about the integration of a TDR Host Sensor with a host that runs Malwarebytes software.

This document does not describe the procedure to set up your Threat Detection and Response account. For information about how to set up your TDR account, TDR deployment best practices, and how to enable TDR on a Firebox, see Quick Start — Set Up Threat Detection and Response.

Configuration Summary

To avoid conflicts between the TDR Host Sensor and Malwarebytes, add these exclusions:

  • Exclusions in TDR for Malwarebytes — For Windows:
    • C:\Program Files\Malwarebytes\Anti-Malware\
    • C:\ProgramData\Malwarebytes\MBAMService\
  • Exclusion in TDR for Malwarebytes — For Mac:
    • /Application/Malwarebytes/
    • /Library/Application Support/Malwarebytes/
  • Exclusions in Malwarebytes for the TDR Host Sensor— For Windows:
    • 64-bit Windows — C:\Program Files (x86)\WatchGuard\Threat Detection and Response\
    • 32-bit Windows — C:\Program Files\WatchGuard\Threat Detection and Response\

If the Host Sensor and Malwarebytes detect and respond to a threat at the same time, this can cause high utilization of system resources, such as CPU, Memory and Disk I/O.

Configuration Details

To complete this deployment, you must have:

  • An active Threat Detection and Response subscription with Host Sensor licenses
  • Malwarebytes for Teams:
    • Malwarebytes version 3.7.1.2839— For Windows
    • Malwarebytes version 3.8.17— For Mac

The TDR and Fireware versions tested for this deployment included:

  • TDR Host Sensor 5.7.1.8870
  • Firebox with Fireware v12.4.1 or higher

The Windows test environment for this deployment included:

  • Windows 7, 8.1, 10 Enterprise 64-bit Operating System
  • Memory (RAM) — 8 GB
  • Processor — 2 CPU Cores

The Mac test environment for this deployment included:

  • macOS 10.13
  • Memory (RAM) — 8 GB
  • Processor — Intel Core i5

Configure Exclusion in TDR

In your TDR account, add exclusions to manually identify paths for files and processes that you do not want Host Sensors to monitor. Before you deploy a Host Sensor on computers that have Malwarebytes installed, add exclusions for the Malwarebytes file paths as TDR Exclusions in your TDR account.

In your TDR account, add the TDR exclusions for the paths shown in the Integration Summary.

Unless otherwise noted, configure each TDR exclusion with these options, which are selected by default:

  • Also exclude subfolders
  • Entities to exclude: Files and Processes

To add an exclusion in TDR:

  1. Log in to your TDR account or managed account as a user with Operator privileges.
  2. Select Configuration > Exclusion.
  3. Click Add Exclusion.
    The Add Exclusion dialog box appears.
  4. In the Path text box, type the path to exclude. Folders specified in an exclusion must end with a backslash.
  5. To apply the exception to all hosts, in the Hosts / Groups text box, specify the group All Hosts.
  6. Click Save & Close.

Repeat these steps to add each exclusion.

Configure Exclusions in Malwarebytes for Teams

To exclude directories used by the TDR Host Sensor, add the exclusions for the paths shown in the Integration Summary.

To add an exclusion in Malwarebytes for Teams on Windows:

  1. Open Malwarebytes.
  2. From the left panel, select Settings.
  3. Click Exclusions.
  4. Click Add Exclusion.
  5. Select the Exclude a File or Folder tab.
  6. Click Next.
  7. Click Select Folder to add the paths shown in the Integration Summary section above.
  8. Click OK.

The Malwarebytes for Teams on Mac does not support the option to add exclusions.
