The application can be removed using its own uninstaller, however, even if you uninstall it this way, there will be files remaining in your computer. The problem is that the uninstaller leaves running executable files. I would like to recommend you to use Revo Uninstaller or CCleaner to remove the files or the remaining registry keys.
Revo will use forced methods to remove all the files associated with the application while CCleaner does a good job cleaning the registry entries.
