MASSIVE data usage from "system"

Anonymous

Blew my data cap (I truly hate Comcast) the last two months by HUGE margins, and have been trying to figure out way. Drilled down into the data usage stuff Windows 10 has built in and find that "System" has used 2.3TB in the last 30 days....

What?

Anyway I can drill deeper into this and figure out what exactly is using 2.3TB of data in a 30 day period? Those are insane numbers. I'm not sure if I could hit numbers like this if I tried. Attached image as proof.

As a side note I doubt I have a virus or malware.
