I'm not sure where you get this. Norton was pathetic for years. More recent versions are better but I have not seen ANY data backed report where it came ahead of Eset and several others in terms of AV/AS.

Unfortunately, I think this one, which is among the leading sites for AV rating, is only available now by subscription.

April Virus Bulletin Report

For me it falls into onced burned (confirmed by a number of friends) that leads me to say avoid Norton.

So they may be better than they were a few years ago, but they're at it again:

Virus Bulletin : News - Symantec slip sparks suspicion, spam

Typical comment:

" note that Symantec's products come bundled with most every out of the box pc and note book. It is the first thing I remove and replace with something much less resource intensive and yet far more effective. *cough avg *cough
