I have had this and I have had one from "Southwest". Since both have been ticketless for years I ignored both. I then had another one and a friend suggested that I forward it to her as they have very sophisticated Firewalls and virus filters. She said that the Firewall caught it and determined that it was a virus and a rather nasty one at that.
What I wand to know is what people get out of this? Is it just sheer vandalism?
