What is MyVideoTab?

The Malwarebytes research team has determined that MyVideoTab is a browser NewTab. These so-called "NewTabs" can 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.
MyVideoTab is a member of the APN family also known as Mindspark/IAC Applications.

How do I know if my computer is affected by MyVideoTab?

You may see this Chrome extension:

these warnings during install:

and this newtab page in the affected browser:

How did MyVideoTab get on my computer?

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

but it is also available in the webstore:

How do I remove MyVideoTab?

Our program Malwarebytes can detect and remove this potentially unwanted program.
You can use their own uninstall instructions first, but I would advise to follow the steps below anyway.
  • 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 MyVideoTab?
  • If you are using an older version of Malwarebytes, you may have to remove the Chrome extension manually under Tools > More Tools > Extensions. Click on the bin behind the MyVideoTab entry and confirm Remove in the prompt.
  • If your browsers have been hijacked, you should read our Restore Browser page. You can read there how to fix additional browser redirect methods.
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 MyVideoTab hijacker. It would have blocked the website before install:
