What is QuizFunWow?

The Malwarebytes research team has determined that QuizFunWow is a browser 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 also displays advertisements.

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