AdwCleaner is a special tool from Xplode. It tries to remove unwanted toolbars, PUPs (Potential Unwanted Programs), etc. http://general-changelog-team.fr/en/tools/15-adwcleaner It is mentioned at http://www.raymond.cc/blog/adwcleaner-search-and-delete-adware-pup-toolbar-and-homepage-hijacker/ It is for example used at http://www.bleepingcomputer.com/forums/ when one-on-one cleaning is done. As with all special tools it has to be used with caution. It is more for when you ask special help by an expert, for example at BleepingComputer. For example there is a "note" at http://general-changelog-team.fr/en/tools/15-adwcleaner giving a warning. The current version is 2.107.
