ghost virus???

No idea what it could be !!! did you tried to scan your computer with programs of detection as Norton ? Trojan Remover ? SpywareBlaster ? and of course AdAware as final ?

I guess that is eerie... Do you have speech to text software installed? In control panel...look for speech icon, open that and see if anything in there is enabled that would allow you to talk instead of type...I'm not familliar with such programs since i dont have it...but your microphone will pick up random noises including from tv, radio, etc. even a thump on the desk or chair might make it type strange stuff if the mic is set too sensitive I would also check in the accessability options...see if anything is enabled in there...same place> control panel. I think xp has some options to enable for those with speech, hearing, vision, etc. challanges. if you dont use such software...disable those functions and ok the changes. If you use netmeeting or the voice chat in msn disabling anything from above won't affect it ..you will still be able to use it normally. Good luck and hope that gets rid of the ghost

Are you on an home network?

I agree with blender. You haven't turned off XP's built in voice recognition software. Look here: http://support.microsoft.com/?kbid=326526#4
