If your WP sites have been hacked. I can help. I had 6 of my WP sites compromised and it was something new. Took me a few hours to figure out. I would suggest upgrading WP and ALL themes if you havent already. It seems to hit the footer.php in your theme and will spread into the plugins... also chmod the themes footer.php to 444. Most my sites are over 4 years old and I have been hit, but not like this.
