This app managed to do what my web hosting service wanted to charge $79.99 a month to fix (since they assumed I'd need round-the-clock protection). Now the malicious redirect script put on my site has been removed and I have a way to deal with it if it happens again.
Thank you so much Eli for not only creating this plugin....but also your diligence to go beyond the call of duty to find a new hidden definition. I'll definitely be adding this to other wordpress sites and checking in regularly. -- Steven H
