What is Fastest Searches?

The Malwarebytes research team has determined that Fastest Searches is a browser 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 one also displays advertisements.

How do I know if my computer is affected by Fastest Searches?

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

and these warnings during install:

and this changed setting:

How did Fastest Searches get on my computer?

Browser hijackers use different methods for distributing themselves. This particular one was installed through their website:

but it was also available in the webstore:

How do I remove Fastest Searches?

Our program Malwarebytes can detect and remove this potentially 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 Fastest Searches?

  • No, Malwarebytes removes Fastest Searches 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 the full version of Malwarebytes would have protected you against the Fastest Searches hijacker. It would have blocked the website, giving you a chance to stop it before it became too late.
