You're right in spirit, but let's kill the "permissions" meme. There's no normally-used Unix permissions that make viruses difficult to implant on Unix systems, and there's nothing on most people's machines that a virus would want access to that intrinsically requires "root".
The leading causes of malware are single-user machines and point-and-click software installation from the web. To the extent that any OS allows these, it's susceptable.
