Exent Technologies deploy their products through GameTanium or FreeRide Games. In order to remove them, please use their installers from Add/Remove Programs or from Start > All Programs. If you encounter problems removing them, use an advanced uninstallation utility like Revo Uninstaller. Download and install the application then use the default uninstallation method. If the uninstaller of the particular application is broken, Revo will try to perform a force uninstall, removing everything that it's related to that application.
You might want to run a scan with Combofix as it will scan deeper into the system for suspicious files, toolbars and registry keys.
