I have a home network consisting of a Telkom ADSL router, a PC, a laptop and two cellphones. The PC runs on Windows XP and the laptop on Windows 7. As soon as I connect the laptop to the net, the "receive" counter starts running and before long has "downloaded" large amounts of data, for no apparent reason. This happens even when I have no websites open and I have been unable to detect what is being downloaded. Only the laptop is affected and the PC and cellphones function normally from the same router. There are no other networks in the vicinity and stolen bandwidth is therefor out of the question. Please help!
