MacKeeper

Recently I've noticed MacKeeper ads coming up as pop-under windows on my computer. It used to happen only on one site I sometimes visited but it now it is appearing more often. Unfortunately, I seem to be only able to block pop-ups not pop-under ads. Any way to stop this thing from happening, especially with this ad?



Also I noticed MacKeeper is adding cookies even though I've got block cookies from third parties and advertisers checked in Safari.
