Helped me insure the weather-de.php malware stayed off one of my sites! After a new customer called to ask if I could help her find a piece of malware in her site, I used this plugin to confirm what I knew. After manually cleaning the site, it gave me the peace of mind I needed to feel I was continually staying clean. Not only did it help alert me to further issues, it played a part in gaining and retaining a new customer. It will hopefully be in my small stable of 'must have' plugins for a long time.
