000webhost is spamming me

Okay, I haven´t used my site for a while now but one day I decide to check on it, and what do I see? My webhost, 000webhost.com, is mass-spamming my website! I have no idea how to remove it but every single time you click on ANYTHING on my site 000webhost.com puts a big fat ad all over the screen, completely blocking users off from my content. They´ve never done this before and one of their ad-slogans is “No banners or ads”. Ironically they´ve even put their “no-ads”-slogan in the very ad they´re spamming my site with.

Basically I´m just wondering… is there any simple way to remove this spam? Could I somehow block it?

Your sincerely
