What is NewtabTV?

The Malwarebytes research team has determined that NewtabTV is a newtab 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 NewtabTV?

You may see these browser extensions:
