After installing uTorrent recently, I found this extra toolbar on my Chrome Browser pages, and tried many things to get rid of it, including even uninstalling the uTorrent program itself, but even that didn’t get rid of it.
But, there was an easier way:
Click on the Chrome wrench icon 
(Top right)
Then move the mouse over Tools
then select Extensions
then
Untick “uTorrentControl2” so that it is no longer “Enabled”
That fixed it for me 😉
