Yep that's definately the nasty CWS. That link will help you clean it up. As for the WinAd - go to Add/Remove programs and uninstall it. Then fix it with HijackThis. After, go delete the file if it's still about. Although, I don't see it in this log.......

Also, delete this folder as well: C:\WINDOWS\System32\golumm

But, in order of importance, I would deal with the CWS before trying to kill anything else.

Good luck!
