Ray, this must be very local to your machine. We have not seen any reports like this, and there are thousands of installations of this app. As Ian says, it should be using negligible resources, and we cannot reproduce your report on any of our testing systems.
I suggest reinstalling the FMS Data Manager application.
Sure, you can safely also disable notifications, or not start it on Windows startup at all, but then you need to remember to update when needed.
