What is 24Search?

The Malwarebytes research team has determined that 24Search 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 24Search?

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:

How did 24Search get on my computer?

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