What is Easy Speedtest?

The Malwarebytes research team has determined that Easy Speedtest is a potentially unwanted program that behaves like adware.
This particular one adds advertisements at the top of the Google search results.

How do I know if my computer is affected by Easy Speedtest?

You may see these warnings during install:

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

and this screen when you click on that icon:

How did Easy Speedtest 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:

Even though the website says the extension is compatible with Firefox, you will see this prompt when you try to install:
