  • 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 WordSearch?

  • No, Malwarebytes removes WordSearch completely.

How would the full version of Malwarebytes help protect me?
