What Is Positive User?
Positive User is a browser hijacker for macOS that may get installed on a computer in a bundle with a free or cracked app or with a file downloaded from a questionable source. A browser hijacker is a piece of software (usually a browser extension/add-on) that can alter Start Page, New Tab Page or Search Engine on browsers and stop users from changing those settings again. Positive User sets the default search engine on Google Chrome to a fake search engine which redirects all searches to Yahoo.
