That’s exactly what I was saying yesterday. There’s no way for Microsoft, Apple, or any distribution of Linux to protect a user from manually running a dangerous program. Admittedly, most home PC’s running Windows are wide open from a permissions standpoint, so running a dangerous program can do a lot more damage than it could on a locked-down Linux machine, but it doesn’t change the point: This virus cannot spread without help. It may be the pathogen, but we are the carriers.
