I would like to add on to my evaluation of The Cleaner that it has a new feature in Version 4 :"Stealth" Here is a quote right from the developer.

I'd like to mention that we have also added a Stealth Mode which hides the file names as well as identifying window titles and could be expanded to cover anything else the trojan authors key on. This renders all AV/FW killer type programs ineffective against The Cleaner Pro. I am not aware of any other AV or AT doing that yet.
