Drop Down Deals is a little screen that pops up on the upper right of my screen when I'm on the internet, regardless of browser. right-clicking doesn't allow me to DO anything (like uninstall). It's not showing up as a program in the programs list. It's just really annoying and it bothers me that it appeared when I did not choose it.
Drop down deals is a browser add on. Select tools from the menu bar at the upper left and then choose add ons. You should be able to remove it from there. You, or someone using your computer, DID choose to download that add on.
