AutoComplete Pro

PLS Help !!!

 

i cant remove Autocomplete Pro wich got to my pc by installing codec c.

what it does is take over every search field i use on any website (wiki YouTube...) and filling it with "search terms" related to ads in the search results. 

happens in chrome and ie.

 

NIS 2012 dont see it.  tried Norton power eraser, finding and removig plugins\extensions, remove program from control panel, blocking codec c with the firewall nothing helps and i cant find AutoComplete Pro on my pc at all .

 

Thanks
