There are several ways to delete it completely...
You can:
- Download a utility app that does un-installs - some are free, some not-free.
- Use Terminal to do it (google how to do it).
- Manually delete associated files.
The last two are not difficult if you know how to work with OSX. However, I recommend the app "Clean My Mac"
http://macpaw.com/cleanmymac because it has other very useful features, esp if you're not a fan of Terminal commands...
Three useful features of interest to you are the "Smart Cleanup", "Uninstaller" and "Maintenance".
Also, I've not used it but, inside an S3D folder along with the app, is an "Uninstaller"
