What is Quick Search Tool?

The Malwarebytes research team has determined that Quick Search Tool is a search hijacker. These so-called "hijackers" manipulate your browser(s), for example to change your startpage or searchscopes, so that the affected browser visits their site or one of their choice.
This particular one changes your default search engine.

  • 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.

Is there anything else I need to do to get rid of Quick Search Tool?

  • No, Malwarebytes removes Quick Search Tool completely.

How would the full version of Malwarebytes help protect me?

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