What is Video Converterz?

The Malwarebytes research team has determined that Video Converterz is a search 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 particular one is a search hijacker and uses a web push notifications service that is blocked by Malwarebytes for fraud.

How do I know if my computer is affected by Video Converterz?

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

and these warnings during install:

You will see this icon in your Chrome menu-bar:

and these changed settings:

How did Video Converterz get on my computer?

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

after a redirect from their website:

How do I remove Video Converterz?

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 Video Converterz?
  • No, Malwarebytes removes Video Converterz completely.
  • If you have allowed the notifications you can read here how to disable them.
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 Video Converterz hijacker. It would have blocked their notifications service, giving you a chance to stop before it became too late.
