FWIW someone accessed my computer last week and took it over. I have a PC in a location where no one else can use it and they got in, got my passwords and had a buying spree at Amazon. My computer was just sitting on and all of a sudden the mouse indicator began to move and use the computer. That was when I first saw the problem. I've closed all the accounts I could, cancelled my CC and accounts that had passwords on the PC, spent hours with Amazon and Mastercard getting this resolved. I have no idea how they got through to me.

That sounds like a case of remote desktop control via a program installed on your computer, such as "GoToMyPC", "TeamView", "Skype", "Hangouts", or similar (there are a bunch of them, some commercial, some freeware). Could even be a remote tech-support thing from some time in the past when you got support from a manufacturer or dealer.

I suggest you crawl through the machine's "Program Files" folders, looking for programs that allow communication between you and someone outside, that include "sharing" a desktop.

If there's nothing like that, you probably got infected with something that's accomplishing that remote control with a trojan of some sort. Get your anti-malware software in gear and scan...
