Ok, thanks. I know Scorpion Saver and Adpeak are not present in the registry, as I have checked several times now. I don't recall what I downloaded that same day, but I know I have gone through my programs list to try and get rid of anything that was installed recently.
There is one extension on Chrome that troubles me. I don't know why I can't get rid of it. It is the last one in the list on the screen shot and is called WebSite Recommendation 2.2:
I cannot delete it or disable it. When I do, it is back and running as soon as I open Chrome again. Does this have anything to do with my problem?
