What is Clean Master?

The Malwarebytes research team has determined that Clean Master pushes notifications and qualifies as a forced Edge extension.

How do I know if my computer is affected by Clean Master?

You may see these warnings during install:

You may see this entry in your list of installed Edge extensions:

and this icon in the browser menu bar:

This is the main screen of the application:

How did Clean Master get on my computer?

Forced extensions use misleading methods for distributing themselves. This particular one was pushed by a fake system popup:

that redirected the user to the webstore:

How do I remove Clean Master?

Our program Malwarebytes can detect and remove this unwanted program.
  • Please download Malwarebytes for Windows to your desktop.
  • Double-click MBSetup.exe and follow the prompts to install the program.
  • When your Malwarebytes for Windows installation completes, the program opens to the Welcome to Malwarebytes screen.
  • Click on the Get started button.
  • Click Scan to start a Threat Scan.
  • When the scan is finished click Quarantine to remove the found threats.
  • Reboot the system if prompted to complete the removal process.
Is there anything else I need to do to get rid of Clean Master?
  • No, Malwarebytes removes Clean Master completely.
How would the full version of Malwarebytes help protect me?

We hope our application and this guide have helped you eradicate this forced extension.

We protect our customers from these extensions by blocking the sites that spread them:
