Norton continues to win awards in third-party effectiveness testing. Lagging behind, though, is Symantec's technical support. While Norton users now have free telephone support, Symantec still doesn't provide enough of a knowledge base, or even an adequate user's manual.
Once again, this year it emphasizes its premium services a bit too much. That said, Norton AntiVirus 2009 presents a remarkable transformation of a product and is worth a second look. Download Now
