FAKE EMAIL: Norton Subscription - "Automatic Renewal service disabled"

I've just received an email said to be from "Norton Renewals" -  suXXXbscription@nortonrenewalzone.com 

 

It's headed "Renew Norton with 6 months of free subscription" and says that the Automatic Renewal service for my subscription has been disabled.

 

It's a nasty of course. I'm sure that I alerted Norton to it the last time it happened but can't remember whether I did so by email or starting a thread.

 

Some Norton subscriber somewhere is bound to fall for the scam - is there nothing that Norton can do to block whoever is issuing these?
