My Blog is Hacked?

whats on line 17 of /home/hisrar/public_html/mc/index.php ??

sounds like an iframe..

Scan your OWN computer for malware, while you’re busy cleaning up your web site.

how to remove iframe on all pages???

Line 17 should be:
require(‘./wp-blog-header.php’);

Did you make any changes to PHP files?
Try putting an original index.php

Anyone plz help me out
