What is Mega Media Start?

The Malwarebytes research team has determined that Mega Media Start 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.

How do I know if my computer is affected by Mega Media Start?

You may see this browser extension:

these warnings during install:

You may see this icon in your browsers menu-bar:

this new startpage:

and this new setting:

How did Mega Media Start get on my computer?

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

as a follow up to installing a serach hijacker:

How do I remove Mega Media Start?

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 Mega Media Start?
  • No, Malwarebytes' Anti-Malware removes Mega Media Start completely.
  • 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 Mega Media Start hijacker. It would have blocked their website, giving you a chance to stop it before it became too late.
