I have had the same offer as NEJ1941, from that same address and also from
norton@nortonfromsymantec.com, dressed up as a Norton ASdvantage newsletter.
It seems like a (very astute, but plausible) scam to me.
I have advised Norton of this separately.
It would be most helpful if Norton could comment generally on the "offer", as to whether it is genuine or not.
