You will hear those sounds with Instant Messenger when someone comes on and also leaves.
I have an Inspiron 9300 XP Home SP2. I use ANG AntiVirus and Zone Alarm free firewall, using verizon DSL. My question: When I have my speakers turned up, we hear the sound of a door opening and then closing quite frequently. It occurs if the comuters is being used or sitting idle.
I it part of a virus/trojen or anything of the like?
