i am using a broadband connection using my telephone line, so i have a small LAN & broadband icon on the taskbar which actually blinks when i send and receive data bytes,

but when i connect to the internet i find that my PC does automatic web browsing even though i dont even open my browser, meaning these 2 icons appear to automatically send and receive data bytes even though i dont enter anything in the address bar, so this could be around 42kb per minutes, but i am sure i have switched OFF all automatic updates from all my softwares
