Which free AV for Vista 64

Until CAVS 3 is released, what free AV would people recommend to use in conjunction with BoClean on Vista 64? I’ve tried AVG and Avast before on 32-bit systems but not found them very effective. The latest AVG might be better because it protectes against spyware too, but I’ve heard it’s a resource hog, at least unless you tweak it to remove some component or other. The other main one seems to be Avira Antivir, I don’t think I’ve tried that before.

Either Avast or Avira is a good choice. Or Trial NOD32 for 30 days :slight_smile: (enough days for CAV 3)
