What is TinyChill?

The Malwarebytes research team has determined that TinyChill 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 web push notifications.

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

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 this changed setting:

and if you have allowed notifications you may see popups like this one:

How did TinyChill 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 TinyChill?

Our program Malwarebytes can detect and remove this potentially unwanted program.
  • Please download Malwarebytes for Windows to your desktop.
  • Double-click MBSetup.exe and follow the prompts to install the program.
  • When your Malwarebytes for Windows installation completes, the program opens to the Welcome to Malwarebytes screen.
  • Click on the Get started button.
  • Click Scan to start a Threat Scan.
  • When the scan is finished click Quarantine to remove the found threats.
  • Reboot the system if prompted to complete the removal process.
Is there anything else I need to do to get rid of TinyChill?
  • No, Malwarebytes removes TinyChill 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 Browser Guard, as well as the full version of Malwarebytes would have protected you against the TinyChill hijacker. They would have blocked their website, giving you a chance to stop before it became too late.
