What is StreamBee?

The Malwarebytes research team has determined that StreamBee 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.
This particular one closes your initial search tab and opens a new one with the same querie on their own search domain. More details in this blogpost.
