What is FunSafeTab?

The Malwarebytes research team has determined that FunSafeTab 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 FunSafeTab?

You may see these browser extensions/add-ons:

and these warnings during install:

and you will see this icon in your browsers menu-bar:

How did FunSafeTab get on my computer?

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

How do I remove FunSafeTab?

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 FunSafeTab?
  • No, Malwarebytes removes FunSafeTab 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 FunSafeTab hijacker. It would have blocked access to the domain, giving you a chance to stop it before it became too late.
