If you have Web Search Assistant/Cool Web Search spyware, get the
CWShredder. However, there are some reports that it deletes unnecessary files depending what is confirmed to be deleted so be aware. I have used the lastest (in early 2005) version of AdAware and SpyBot but both could not remove it (however, future definitions may have the abilities). Don't forget to get
SpyWare Blaster preventing spyware to be installed.
