how to remove bo-browser malware that refuses to be uninstalled

Bo-browser is bugging me and is a threat to my pc that Norton does not protect me from.  Tried uninstalling through control panel on windows 8 but it goes into a loop saying that all Bo-browser windows need to be shut, but there are none open.  Tried uninstalling again, same response in this never ending loop! Any suggestions as to how to get rid of it through the Norton 360 subscription that I pay for annually.
