"App of the Day is a feature of Pet Match" on each page of Safari
This is spam, introduced by an extension, through superfish.com. AdBlock is not the cause! AdBlock blocks the injected ad, so the extension inserts the text equivalent.

Enable AdBlock so that the text is shown, then disable other extensions that you have enabled, until the text is no longer inserted.
