The drivers are for the Garmin ANT USB-m device. It's a USB device that connects to PC through a USB port to store and manage the data on the USB device. If you know you don't have such device, then I recommend to uninstall it. Try using Revo Uninstaller. Even if it can't uninstall the application normally, it will force it to uninstall by wiping out all traces of its presence from the system.
After that, try running AdwCleaner. If it's malware, AdwCleaner will remove it from your computer.
