What is Speedomizer?

The Malwarebytes research team has determined that Speedomizer 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 one uses the Ookla Speedtest that you can visit directly without installing the extension..

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

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



and this changed setting:



You may have seen this warning during install:



and you will see this icon in your Chrome taskbar:



How did Speedomizer get on my computer?

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



How do I remove Speedomizer?

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 Speedomizer?

• No, Malwarebytes removes Speedomizer completely.
• You may have to remove the Chrome Extension manually under Tools > More Tools > Extensions. Click on the bin behind the Speedomizer entry and confirm Remove in the prompt.

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 Speedomizer hijacker. It would have blocked the site that installed the extension.
