The problem is that when I am idle at the desktop and doing NO Internet activity AND the Internet Gateway icon (Control Panel, Network Connections) status is "connected", there is a lot of bytes sent to and from the Internet. It measures 16Mbytes of downloads per hour! Why/what is this Internet activity. It is worth noting that the count of bytes sent is approx 90% of the bytes received. I run WinXP Home, NOD32 V2, with Broadband modem/router. This problem occurred before and after XP SP2. I have Automatic Updates turned OFF. There are no viruses on the system and a run of Adaware and Spybot brought up no spyware on the system. I have done some testing to reveal that I beleive it is the nod32krn program that is causing the problems. Whenever I remove nod32krn from the running Processes list, the download count slows right down to a crawl. Has anyone experienced this problem or have a solution? My work around at this moment is to disconnect the Internet Gateway when I am not using the Net.
