What is OiT?

The Malwarebytes research team has determined that OiT 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.

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

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


and these warnings during install:



Despite this warning the install was successful

How did OiT 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 OiT?

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 OiT?

  • No, Malwarebytes removes OiT 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 OiT hijacker. It would have blocked their website, giving you a chance to stop it before it became too late.
