There are many opinions as to why most virus writers write their code to affect Windows but for the most part seem to ignore Linux. Some think this represents an "apples and oranges" situation since each operating system kernel is dissimilar from one another. Now we see a "proof of concept" virus that can affect both Windows and Linux...

Now we see a "proof of concept" virus that can affect both Windows and Linux machines at the same time. While the particular virus reported by Kaspersky Labs seems to have a low impact on affected systems, it may be a sign the the sense of security Linux users have experienced should be re-evaluated. In the relatively near future, Linux may not be able to brag so loudly that it is virtually immune to viruses and other malware. -Trip

I'm, unfortunately enough, not an OS developer, nor do I have any relevant experience, but since it's in ASM, how does that effect permissions, kernel level activity, etc? I'm thinking that, otherwise, the fact that it is cross-platform doesn't mean all that much...
While it is certainly possible to infect a Linux system, I find it more than a little suspicious that all the 'ominous' warnings come from Windows based AV software vendors, or MS itself. I expect that sooner or later someone will write more virus specifically for Linux, but I wouldn't get my panties in a bunch over the prospect of it.

In the mean time run clamav, and schedule chkrootkit. Not a bad Idea on any system. Personally, I run a text based email client which eliminates or at least minimizes most modes of infection anyway. Truthfully, most virus infections come from some idiot opening the door by clicking on something when they know damn well they shouldn't. Windows users are notorious for that. Let's hope Linux users are at least a little smarter.
