Note this image of my customize settings:
You can clearly see what appears to be a scroll bar there along the left (is also on right of screen), despite the indicated settings. Further, I have this in my .emacs:
(custom-set-variables
;; custom-set-variables was added by Custom.
;; If you edit it by hand, you could mess it up, so be careful.
;; Your init file should contain only one such instance.
;; If there is more than one, they won't work right.

Note the line where scroll bar mode is set to nil.
Why is that ugly bar there on the left?
That is not a scroll bar, that is the fringe. You can control it by customizing the
fringe-mode
variable. If you don't want to do that manually, do M-xcustomize-variable
RETfringe-mode
RET, choose "No fringes" from the Value Menu and save.More info about window fringes here.
