There is a backdoor in your site. Something like that http://forums.digitalpoint.com/showpost.php?p=12950936&postcount=8 Try to check all eval, system, base64, fopen, include etc functions in your scripts. http://forums.digitalpoint.com/showpost.php?p=13330348&postcount=6 Try to search for non image or executable files in directory`s like /images of /uploads You can also contact me about security of your site. I can check your site for bugs.
There are backdoor and bugs in one or more of joomla components or your web server isn't secure. There are tool that can help you diagnose what's really wrong.
