You don't need a program for that. The options in Explorer will let you do that automatically.

Go to the Tools menu, select Folder Options, then click on the View tab. There are options in there about not saving thumbnail caches and about automatically hiding system files. Showing system files will cause thumbs.db to appear in the normal folder viewing process. Preventing Windows from caching thumbnail images will prevent thumbs.db from being written in the future, but will not delete any that already exist in random places.
