I bet they simply edited some templates, try reverting any newly customized templates via style manager before doing anything else. *Also please note the queries I list in my blog article, you can replace the words we are searching for w/ anything you wish for example:
PHP Code:
SELECT styleid, title, template FROM template WHERE template LIKE '%adf.ly%';
