Hi im running Vista Ultimate and i connect to the internet via a wireless network. The network i normally connect to is set to "connect automatically" and usually just connects to it. But sometimes when i leave my computer on all day or night il come to it and find it has disconnected from "BT Hub ect" and connected to a network called "ANY!" which doesnt have any encryption or internet acess but has set itself to "connect automatically". I have NOD32 running constantly and am quite sure i dont have a virus i just have no idea why this is happening.
