I left my PC on last night to run a viruscan. When I checked it this morning I had no viruses but I noticed that something was downloading data onto my PC from the internet. I determined this by checking a program I have called DU Meter which monitors the flow of network traffic across my ethernet connection. Other than Norton Antivirus, no other programs were running and as far as I could tell there were no programs running that would be downloading data from the net.

My question is, how can I determine what was causing this data transmission across my internet connection?

Thanks,
Ben

That's a scary thought bro. Two things could be happening, you got some spyware that eats up CPU usage, or I'm dreading if you have a cable/dsl and no firewall (or a crappy one) and someone is using back orifice or some equivlent. Meaning someone is accessing naughty files and sites thugroh your computer IP (Like the FBI database or NASA crap). This would be bad, no, this would be very bad. I hope you comprehend what I mean. I hope you got it fixed right away. Oh and sorry if this scares you out of your pants.
