What is Our Search Window?

The Malwarebytes research team has determined that Our Search Window 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 effected by Our Search Window?

This is how the first screen of the installer looks:

And you may see these browser extensions/add-ons:

Browser hijackers use different methods for distributing themselves. This particular one was bundled with other software.

How would the full version of Malwarebytes Anti-Malware help protect me?
