What is Boost?

 

The Malwarebytes research team has determined that Boost 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 Boost?

 

This is how the first screen of the installer looks:

And you may see these toolbars:

or this entry in your list of installed programs:

How did Boost get on my computer?

 

Browser hijackers use different methods for distributing themselves. This particular one was bundled with other software.

 

How do I remove Boost?

 

Our program Malwarebytes Anti-Malware can detect and remove this potentially unwanted program.

  • Please download Malwarebytes Anti-Malware to your desktop.
  • Double-click mbam-setup-version.exe and follow the prompts to install the program.
  • At the end, be sure a check-mark is placed next to the following:
    • Enable free trial of Malwarebytes Anti-Malware Premium
    • Launch Malwarebytes Anti-Malware
  • Then click Finish.
  • If an update is found, you will be prompted to download and install the latest version.
  • Once the program has loaded, select Scan now. Or select the Threat Scan from the Scan menu.
  • When the scan is complete , make sure that everything is set to "Quarantine", and click Apply Actions.
  • Reboot your computer if prompted.
Is there anything else I need to do to get rid of Boost?
  • No, Malwarebytes' Anti-Malware removes Boost completely.
How would the full version of Malwarebytes Anti-Malware 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 Anti-Malware would have protected you against the Boost hijacker. It would have warned you before the rogue could install itself, giving you a chance to stop it before it became too late.
