coming out of the computer, it is probably a hardware problem of some sort such as a fan maybe.
On 2 occasions in the past week, I've heard what sounds like my PC making a long quack sound. Nothing else, just the sound.
I thought it might be my chair, but I'm not so sure.
I updated spybot, adaware, and Norton and ran each in safe mode with a reboot in between and they detected nothing other than some cookies.
Is there a duck/quack virus out there?
