A browser hijacker is a small program or registry setting that is responsible for changed IE start and search pages. If your browser starts with a different start page (one you haven’t changed yourself), you most probably got hijacked. Intelligent hijackers do not only change these pages, but also add a small file that will restore the hijacked settings upon each system start. Hijackers often use ActiveX installation programs and/or security holes.
