I received the critter twice today (first time, for me).
Both times, Norton stopped it at the gates, but couldn't fix it.
Flagged it to me as "unrepairable" and stuffed it into quarantine - from where it was deleted.
Both e-mails came with "national helicopters.com" address. The e-mail title said "*****, Try again" (***** was my own e-mail name). I have never written to this company, nor had anything esle from them.
