I'm not sure what's going on here...

While I was watching a netflix video, my computer suddenly shut off with no warning. Upon restarting it, a message came up that several bluetooth items had been installed (I wish I had written down the exact wording of the installation message). I don't want and didn't give permission for this to happen. I looked at system restore points, but it claimed that nothing was there to uninstall since the last windows update. I also don't see anything with bluetooth in the name in devices or installed programs.

So far my system is operating normally as far as I can tell, but this worries me and I would like to know what just happened and what I should do about it.
