Windows Defender (comes with OS, I don't like it)
FortKnox (this is one I love and recommend)

Spybot S&D

AVG Free

What I personally use:
Spybot S&D for daily use, though I remove it when extensively installing things.
FortKnox. Comes highly recommended.
Avast. There are better ones out there, but they're not free. AVG is very processor intensive.
