Trend Micro CWShredder is the premier tool to find and remove traces of CoolWebSearch – the name for a wide range of insidious browser hijackers– from your PC.

CWShredder removes these browser hijackers. CoolWebSearch installs dozens of bookmarks–mostly to porn Web sites–on your desktop, changes your home page without asking, and continually changes it back if you attempt to correct it. Furthermore, it significantly slows down the performance of your PC, and introduces modifications which cause Microsoft Windows™ to freeze, crash or randomly reboot.

Originally developed and updated by a graduate student in the Netherlands, CWShredder™ is now maintained by TrendMicro. The previous version can be found here.
