What is TigerPDF?

The Malwarebytes research team has determined that TigerPDF 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 TigerPDF?
