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.

Is there anything else I need to do to get rid of Clean Master?

• No, Malwarebytes removes Clean Master completely.
