And they're on to that tactic now, too. A lot of these bastards are now
putting in checksums and other code-checks in header.php (and functions.php,
and elsewhere) to check for changes to the encrypted footer.php code - and

(Not that such checks are anything more than an annoyance, since they, too,
can be cleaned up and removed.)
