What Are Browser Hijackers?
A browser hijacker is a program, malicious or otherwise, that modifies the home page or search settings of a web browser. Some hijackers will modify Windows shortcuts without your knowledge to automatically load a particular website when you start them. Doing so could cause websites to launch in programs that would not normally browse the web, such as Microsoft Word. Browser hijackers are usually bundled with free programs that you download from the Internet. These programs are free because they include adware including browser hijackers which generate revenue for the developer when installed. Many hijackers can be removed by simply uninstalling them from the Windows Add or Remove Programs or Uninstall Programs control panel. Some are more stubborn and require anti-virus programs or specialized tools.
