What is Fanatical Assistant?

The Malwarebytes research team has determined that Fanatical Assistant is a potentially unwanted program (PUP) that behaves like adware. These adware applications display advertisements not originating from the sites you are browsing.

How do I know if my computer is affected by Fanatical Assistant?

You may see these warnings during install:

and you may see this icon in the browsers menu-bar:

How did Fanatical Assistant get on my computer?

Adware applications use different methods for distributing themselves. This particular one was installed from the webstores:

How do I remove Fanatical Assistant?

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 Fanatical Assistant?

  • No, Malwarebytes removes Fanatical Assistant completely.

How would the full version of Malwarebytes help protect me?

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

As you can see below the full version of Malwarebytes would have protected you against the Fanatical Assistant adware. It would have blocked the installer before it became too late.
