I have had the limited "USB" modem for 6 months and all of a sudden last month went over the 5120. Not by much, but I had never even come close to going over before. When I checked daily use on the bill there are several days of higher than my normal use. It didn't take many days of triple and quad to trigger extra charges. The time and sites that I use have not significantly changed.
Now, someone tells me that my computer can be running things in the background that I don't even know about. Someone also mentioned that the little light on the front of my laptop flashes when info is being received.
Can someone tell me what the heck is happening and how I can stop it.
