The same thing happened to me I thought someone invaded my computer when I was typing an email and I saw words being typed, I didnt realize I activated the microphone setup when I installed XP, the resolution was to unplug the microphone and make sure you have a microphone with an on off switch. I should tell you that I have 30 years computer experience and my son is a hotshot Unix Administrator, so he's a nerd by birth, we had a really good laugh over this, and I still burst into laughter when I think about it, a computer can make fools out of all of us.
