Removal instructions for focusbase

Recommended Posts

What is focusbase?

The Malwarebytes research team has determined that focusbase is a browser hijacker. These so-called "hijackers" alter your startpage or searchscopes so that the effected browser visits their site or one of their choice. This one also displays advertisements.

How do I know if my computer is effected by focusbase?

This is how the start-screen of the installer looks:

And you may see these toolbars/add-ons:
