Spyware Information: CWS.HomeSearchAssistent

This is a hijacker application. Hijackers take control of your web browser's settings, and usually change your homepage, search page or other default pages to point to web sites owned by the hijacker. Since the hijackers can make money based on the number of visits to their web sites, they benefit from forcing you to view their web sites each time your web browser opens.

Hijackers don't normally damage your computer or steal your personal information.
