Is it normal for a computer running Windows 7 and MSE to lose almost 3 GB of bandwidth in a period of 5 hours downloading automatic updates? The connection is iBurst. 2.8 GB of bandwidth has disappeared overnight with little internet surfing, no downloading of videos, etc. The explanation given by iBurst when asked what had happened to all the bandwidth was that it must have been automatic updates. It just seems a bit much though.
