Ignore any ads for MacKeeper. It would cause more problems than it's worth.
You can block pop up ads in Safari.
From your Safari menu bar top of your screen, click Safari. From the drop down menu click Preferences then select the Security tab.
Select: Block pop-up windows

One other thing you can try (if you have Easy Find). Feed the name Mackeeper into its search box and delete anything which shows. You may have picked up a trigger to MacKeeper when surfing around in other areas.
