How do i remove the annoying "Powered by Zedo" Popups & more...?

I have had these same problems recently, i downloaded Hitman Pro which is freeware. It sort of combines techniques from different antispyware and antivirusprograms. It either installs them on your pc or just lets them do a onetime job. I think it was Ewido that found some tracking cookies and some other stuff which my antivirusprogram had not detected. When these were removed by Hitman Pro my problems with the "powered by Zedo" popups were gone. I also had problems with rogue antyspyware and other software for pc that was forcing itself on me via popups accompanied by very official looking messages from internet explorer but they're gone too. Good riddance!
