I could knit-pick your grammar, but is this overall claim based in empirical research? Linux certainly has it's flaws and while it's not susceptible to WINDOWS malware, it certainly is to a variety of others. Perhaps take a look at http://insecure.org/ or http://www.packetstormsecurity.org/. Both of these sites maintain lists of exploits to various version of Linux and many other types of GNU software as well. Rootkits most generally fall into the realm of 'malware' and once you've got root, baby, you've got the world.
