System Requirements: Malwarebytes Version 4.0 no longer works on Windows XP or Windows Vista. However, Malwarebytes 3.x, will be supported for the foreseeable future.

Windows 10 Note: Although Malwarebytes is an antivirus software, if you use another program as your antivirus (Windows Defender, McAfee, etc.) as your antivirus, it is necessary to make a change in Malwarebytes. Go to Settings > Windows Action Center, change the setting to "Never register Malwarebytes in the Action Center". Malwarebytes 4.0 will continue to run with the installed antivirus in compatibility mode.

Microsoft Defender: If you use Microsoft Defender as your antivirus software, do the following:
  • Open Malwarebytes.
  • Press the little gear at the top right.
  • Choose the Security tab.
  • Enable the three options under the title Scan options.
  • Disable the option under the title Widows Security Center.
