almost all Avs, free are better tahn Windows defender cause defender is a baseline product. basic protection.
I have a high opinion of Panda. Very good with resources, good with features, good interface, good kill ratio. I've deployed it on hundreds of machines, many of them not very powerful. It's a delight to turn off Windows Defender, including the pre-Win8 edition.
