SearchForFree is a browser hijacker.  If you search for a phrase or term while using Microsoft Internet Explorer, it will redirect your search away from your engine of choice and use Searchforfree.info instead.

Browser hijackers typically strong-arm Explorer and other browsers by modifying host files, or by falsifying DNS queries.  SearchForFree’s presence on your computer likely indicates that some of your system files have been modified.  A free scan with SpyZooka will let you know what other threats may exist on your computer.
