I entered on my websites and i saw that was hacked(the bage is blank and in the source of page is a iframe with aachristmas.com). I installed the wordpress again, but when i restored my old database .. same problem. I searched on database for "aachristmas" or something but no result.
Take a look: http://www.porngros.com, http://www.movie2010.info
What can i do?
