AppTrasher is a shareware uninstall utility using the Levenshtein Distance algorithm to find related files

Applications distribute several files throughout your system storage devices. Deleting a application itself is mostly not enough and will leave several files untouched.
Apptrasher uses a special search algorithm to find all related files and deletes them when asked.
