What is CheckAMap?

The Malwarebytes research team has determined that CheckAMap 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 also uses browser push notifications and adds advertisements to your search results in the form of recommended searches.

How do I remove CheckAMap?

Our program Malwarebytes can detect and remove this potentially unwanted 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 CheckAMap?

  • No, Malwarebytes removes CheckAMap completely.
  • If you have allowed the notifications you can read here how to disable them.

How would the full version of Malwarebytes help protect me?

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

As you can see below Malwarebytes Browser Guard, and the full version of Malwarebytes would have protected you against the CheckAMap hijacker. It would have blocked their website, giving you a chance to stop it before it became too late.
