Q: I have a Dell 8700 desktop running Windows 10 connecting to the internet via AT&T wireless hot spot. I use Firefox as my browser. My problem is that something is running in the background with no notice or indication to me. It is consuming my limited data limit. Whatever it is, it repeatedly connects and downloads/uploads more than 500 megabytes each time. Nothing shows up in my downloads folder or anywhere else that I can find.
