What is browser hijacker?
Browser hijacker is a malicious program, usually a web browser plug-in or add-ons, which modifies web browser settings in order to change default search page, home page, new tab or error page. After that, it starts unwanted redirects to undesirable Internet sites. A browser hijacker also can record all web pages the user visits and send gathered information out through a background Internet connection.
Practically all browser hijackers are created for commercial, advertising or marketing purposes. However, there are lots of malicious versions of these programs that similarly to spyware or adware threats can be installed on the system without user's consent and often hide deep inside the system for avoiding their removal.
