Why Does It Sound Like I Have Keylogging VIOP Voyers on My Connection? Is That the New Cool Voyer Thing to Do

It sounds like more than one person are just watching my browser session and talking about it over a wireless or regular connection line. I am sitting here quitly in my house and there is no one around, but it sounds like some sort of conference call is hovering around my machine? They even delete key strokes and move my mouse it is really anoying. Does anyone know how to detect active spying, voip, or other IM voyer techniques that are being used online? If anyone could tell me how to check for these anoying security breaks, that would be awesome. Thanks.
