Fascinating. I caught a volume change to mute. A small window came up for an instant, maybe a couple of inches by a half inch. I couldn't read it, as it faded quickly. The icon changes when it's muted.
Meanwhile, spyzooka keeps finding that bug, if there's a bug. Win32.Worm.AutoIt [TrojanHorse]
Tells you to run in safe mode and never finds it. Then you run it later in regular mode and it's back. Webroot isn't picking up anything. I haven't had time to go back to this and contact the vendors. Dang computers!
