One-line text "ads" for cialis started showing up on some of my posts. And they link to this website: http://www.score-louisville.org/component/page,shop.browse/category_id,7/option,com_virtuemart/Itemid,6/
I've removed the text and links so I can't show any examples right now. But it looks like someone may have hacked my site???
Is this a WordPress issue or a hosting issue?
