I'm assuming that you're using Chrome and it's pinned to task manager. That's just a short-cut icon. When you single click it then another Chrome icon appears and is the 'live' one. Hovering the mouse pointer over that one will show a small window of the opened browser. I noticed in one of your images that you have SearchLock as an extension. If you don't want it then go to Chrome's extensions, then delete it.
