I downloaded BitMeter a few hours ago to check if my bandwidth was being used without my knowledge. To my unpleasant surprise it was. I turned off my web browser and I started no programs yet DL rates fluctuated between 5 - 15 kb/s per second and upload rates with half that. I restarted my computer and logged in, left it running for 90 minutes and when I got back it said I DL'ed 45 mbs and uploaded about 15 mbs!!
Is it possible that I'm mistaken and this is a natural occurrence? How do I locate what files are actually being sent and received and what program is using them?
PS: There is only one machine in my house with one modem and no wireless router. I'm using a 5mb cable dsl connection.
