What is Web Protection for Chrome?

The Malwarebytes research team has determined that Web Protection for Chrome 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.

How do I know if my computer is affected by Web Protection for Chrome?

You may see this entry in your list of installed Chrome extensions:

How did Web Protection for Chrome get on my computer?

Browser hijackers use different methods for distributing themselves. This particular one was downloaded from the webstore:

How do I remove Web Protection for Chrome?

Our program Malwarebytes can detect and remove this potentially 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.
  • 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 Web Protection for Chrome?

  • No, Malwarebytes removes Web Protection for Chrome completely.

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 Web Protection for Chrome hijacker. It would have blocked their website, giving you a chance to stop it before it became too late.
