The Valentine's Day Spyware Surprise

On Valentine's Day we found spyware on our computer.  It was a huge, nasty, keystroke-collecting thing apparently installed year before last by hand when someone broke into our house looking for our medical insurance records (and audio-taped themselves doing it, the dorks) and set it to auto-download on V-day.  We don't think it activated last V-day because we weren't doing much online then as we were still busy moving.

This is an infuriating, intolerable invasion of our privacy.
