Norton has high detection rates because of the information that they gather from their community. They are usually first in the line of AV's to get updated malicious code to add into the detection for newer releases of their AV. They have a really big community which makes them that successful in my opinion. That's why Microsoft Security Essentials was good right off the bat when it came out. Microsoft already has all of the information they need. They just needed to put something together that would detect against all of the malicious code that they already know about.
