These two things have NEVER been on my site before, and they just appeared. One leads to some site trying to sell what looks like products made by other Oxwall people, and the second one is some foreign social network.

No one could've done this without breaking into my ftp somehow and adding them, or something like that, but I want to know how I can remove them from my footer.

Update

Appearently, one of these link to a site that claims to be a site software, that is just Oxwall software their selling.
