This script still doesn't do any cleanup on its own, it's only informative about some suspicious code in your Joomla! installation.
This script is far from being 100% accurate. It has just a few patterns at this moment, and the false-positives are very well to be expected. So you may only use it wisely and with caution. I do not take any resposibility for any damages you might suffer by following some advices or results of this script.
