This kind of apps is one of the most commonly encountered forms of unwanted software for both Mac and Windows computers. While the representatives of the browser hijacker family are not as threatening as more dangerous software types, such as Worms, Banking Trojans, Spyware, and Ransomware viruses, they could still turn out to be a major inconvenience if they remain in the browser for long enough.

Some of the first browser hijacker symptoms most people report are different unwanted changes in their browsers. A replaced homepage address or default browser search engine inside browsers such as Firefox, Safari, or Chrome is what lets people know that some kind of unwanted application has managed to get itself attached to the system’s main browser. One of the most frustrating parts about such unauthorized browser changes is the fact you won’t be allowed to reverse them so long as the hijacker app stays added to the browser.
