This virus has become more devious.
I had this CW infection that kept coming back after you would think you had deleted it. CW shredder was useless. So was SPYBOT, Hijackthis and Adware and Microsoft AntiSpyware. It was a vicious circle.
I finally, after figuring out what processes were causing the return, got hold of X-raypc. Cool program, free and small. It gives you info on all running processes and lets you off load them and/or delete the file causing the running process. Careful what you delete!

It is a miracle program.
