For a while now I've noticed that my network [modem, static IP] has some unusual activity, being that the amount of sent packets is much larger than the ones that appear as received. And I am not referring to p2p connections; if I load a web page or download a package over a browser, the sent data always accounts for about 1.5 - 2 times over the amount of received data. I normally assumed some spyware infestation, so I ran multiple scans [Malwarebytes, Spybot, Superantispyware]. Multiple infections were discovered [mainly "backdoor trojans"] and taken care of. Now the HJTlog looks clean. But the high rate in traffic persists in the windows' network status. I tried Netlimiter to monitor the traffic rate - it looks normal, the transfer rate for say loading a web page is what it should be and it appears as the only process accessing the network; if the connection is idle, it stays that way. But in windows' network status, the traffic is continuous [it never gets "idle", it just slows down the transfer rate] and, as before, the sent packets are larger then received ones. What could account for this behavior? The network adapter is Nvidia nforce4 - could it be just a driver related problem? [can't update it, anyway, nvidia really pulled the plug on some old releases]
Thanks in advance
