BT Keyboard driver issues

Hello, I have a Dell Latitude 10 with the Kingston Keyfolio case. Recently the keyboard has stopped connecting to the tablet.. I have tried turning off the keyboard in the hope that it would re-connect. In Device Manager, I have uninstalled the BT Keyboard driver and rebooted with the keyboard off. With the keyboard still off, I noticed that the BT Keyboard driver had reinstalled itself and on checking the driver have noticed that the Driver provider is ESET - our Anti-Virus provider. Have looked on the Kensington website and and can't find a driver. Anyone know where I can find this driver? Thanks Tony
