If I were you, I would avail myself of the free trials of some really good anti-spyware programs such as CounterSpy. It is far more powerful than any free software out there.

Try their free 15 day trial of the full system and see what it picks up.

It cannot hurt to try and unlike anti-virus programs, you can run more than one anti-spyware program on your computer.
