I think a firewall is assumed. To be attacked by a worm you need to have ports open to the attacker.

It could also be another factor. When I use Linux I put my distro on and very few other items, usually codecs and any items after the fact come from a trusted repo. It has everything I need. When I was using Windows, I had to layer this and that and install all sorts of things.

Perhaps Windows users get so use to installing applications from far and wide to achieve a full tool set that they are more prone to trojans and malware.
