So.... that bit of malware that secreted itself away running in the background, capturing your webcam images for later use.... that couldn't possibly manipulate what device status is displaying for a given device in your holy grail Device Manager?

Or perhaps go and read Wired then find another profession that better suits your wanton incompetence.
