Browser Still Downloading After Closed After Bdts 2009 Installed On 2 Systems.

Just installed BitDefender Total Security 2009 on 2 systems at my home.


And i have started getting an issue with both systems continueing to use up all my bandwidth, for example...


I load up and start to watch a youtube video but i decide early into the video that i no longer wish to watch this video, so i close the browser(Firefox or IE7/8 it makes no difference)


But my bandwidth is still chewing away like i'm continueing to stream the video.


One Machine is XP and one machine is Vista.. the only program that has been installed onto both systems the day the problem started was BD Total Security 2009.


Please help.
