How do I remove Memory Game?

Our program Malwarebytes can detect and remove this unwanted program.
  • Please download Malwarebytes to your desktop.
  • Double-click mb3-setup-consumer-{version}.exe and follow the prompts to install the program.
  • Then click Finish.
  • Once the program has fully updated, select Scan Now on the Dashboard. Or select the Threat Scan from the Scan menu.
  • If another update of the definitions is available, it will be implemented before the rest of the scanning procedure.
  • When the scan is complete, make sure that all Threats are selected, and click Remove Selected.
  • Restart your computer when prompted to do so.
Is there anything else I need to do to get rid of Memory Game?
  • No, Malwarebytes removes Memory Game completely.
  • If you are using an older version of Malwarebytes you may have to remove the Chrome Extension manually under Tools > More Tools > Extensions. Click on the bin behind the Memory Game entry and confirm Remove in the prompt.
How would the full version of Malwarebytes help protect me?

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