I have contracted an annoying “popup ????” that occurs every time I enter a search item in Amazon or Ebay. A window title “search enhancer” pops up giving me the option of searching the web or searching the site. I don’t know if this is friend or foe, but I am reluctant to use it, don’t desire to use it, don’t need to use it. Can someone tell me if there is a way I can find this somewhere in my computer and delete it?
