This is the generic detection for a large family of adware that used to specialize in Internet Explorer toolbars as a means to hijack browsers. While diversifying to cover the most popular browser, they concentrated on extensions that hijack the search providers of these browsers, sometimes while enforcing a policy so the user cannot easily undo this change.
Malwarebytes can remove Adware.NeoBar, but sometimes it requires some extra actions to get the browsers settings back to the state they were in before the infection. We post removal guides when we run into such special cases.
In general, we advise to visit our browser restore page if your browser has been hijacked.
