I am a longtime nod32 user and love the program. I was surprised to hear that av comparative indicated that their march 1 on demand release will be lowering nod32's rating from advanced+ to advanced. First time in a long time. The complete results are not out yet, but an overview is available at their website (can't link to it), under comparatives and above the notebook info. Being no expert in this area, I would not even know why but results will be forthcoming. Kaspersky and a few others again top the list. This website seems to have more validity as relates to testing than most.
