Today I was out for most of the day, and barely used the internet, I did not watch any videos or stream or even download anything, except a little bit of browsing. So I left my PC on for the day so it was in standby for about 7 hours, I come back and Net meter (A bandwidth monitoring App) and it says I have used 600 MB! I don't know how on earth this is possible! Could something be wrong with the App, or is there a background process that somewhere that could be draining my bandwidth!
