Norton Popups

Norton recently eliminated a piece of low-risk malware from my machine -- specifically Yontoo.C.  Ever since then every ten minutes or so I get a popup from Norton telling me that they have removed Yontoo.C.  I can find no way to shut it off.  Perhaps the following is relevant (there it goes again!): I recently replaced Internet Explorer with Google Chrome, which produced a deluge of popups.  So I ran blockadplus.org, which took care of the great majority of them.  Since I can't seem to fight my way through to Norton, does anyone have any suggestions on how to get rid of the Norton popup?
