"Is there a way to stop these "ads" popping up all the time?"
If you install an 'ad-blocker' on the browser's you use, including Google Chrome, then that should solve your problem.
You can get 'ad-blockers' for your particular browser from the internet or add-on within the browser you usually use. 'Adblock' or 'Adblock Plus' will usually do the trick. Make sure that you download and install from a reputable website, like the original website.
