Strange search bar appearing when browsing internet?

It happens when I search on wikipedia and several other sites (suprisingly, Google is unaffected). I posted pictures of a "sample" search (literally) and the settings box for this intruding search tool. I checked and I don't have AcPro (Autocompletepro) or Complitly on my machine (both are by the same company, SimplyGen and both are "powered" by Yahoo search).

I have doubts that they are the programs causing the unusual activity, as the interface does not match, but a setting says "I want AcPro enhanced experience..." so maybe it is related somehow.

I checked and none of these processes are running: AutocompletePro, AutocompletePro.exe, AutocompleteProMon.exe

Look at the pictures are decide for yourself. Please help me get rid of it. It is an annoyance.

Also, I have a full scan running so I will let you know tomorrow if it is a virus and it has been removed.

no safe mode.

Chrome

nothing there that looks out of place.

no problems with other browsers. But they are damn slow compared to Chrome, so nothin' doin'.
