There's an old saying that does the rounds from time to 
time ................ "Never say never!"

Yes there are the odd Linux/Unix based Virii. Most are what is called "proof 
of concept" as I understand it. Then we also know of things called "root 
kits" which are often aimed at Linux/Unix based systems. Even then there are 
malware that can act independent of OS, i.e. JS (Javascript) for instance 
which are based on code commonly executed in the browser and don't require a 
given OS to be present. Such malware can affect both Windows and Linus users 
alike if they happen to be unaware of them. One reason I advocate the use of 
Firefox and the "noscript" plugin.

I've over the years seen the argument that there are no virii (malware) that 
target Linux. Alas what a goodly number of people forget is one doesn't need 
to target an OS (operating System) in order to target the unsuspecting. 
Javascript for instance being browser supported is OS independent and 
therefore can attack both Windows and Linux based users alike depending on 
their level of awareness :(
