Unable to load driver for ATmega16u2 DFU

Hi - I am running Windows 7 Professional and am struggling to load the right driver for my Arduino Uno so that I can see a port in my tools menu. When I connect the Uno to my laptop, I see the device as "ATmega16u2 DFU" in my device manager menu. However, none of the drivers I downloaded seem to work and Windows cannot find a driver either.

Have checked through this forum and not found a clear answer to what I could try next. So any help would be appreciated. If I have missed a link to a solution, please point out the link to me.
