Flexibility3 theme

I have uploaded this theme and it seems to be a great theme for a beginner. I have just noticed that there are two very small ads on the front page. Just a couple of words in the top left corner and at bottom of page and not very noticeable. I have not put them there. One is a gambling ad and other for car insurance. Any idea how to remove them as there is no indication in the settings that they are there.
