iTrash is an uninstall utility that uses a special search algorithm (Levenshtein Distance algorithm) to find all related files and deletes them when asked.
Applications distribute several files throughout your system storage devices. Deleting an application itself is mostly not enough and will leave several files untouched. Requires OS X 10.7 or later Home Page - http://www.osxbytes.com
