RE: 'It will definitely be something worth trying.'
You do not have the slightest idea of what running windows files under WINE through the linux file system could mean.
Of the Top-Five-Net-Virus collection (Klez, MyDoom, Sobig, SCO, and SomeTool) only MyDoom could not be run under WINE (actually this is a matter of time).
It is true that they cannot infect your linux system, as even more true is that your OS will be turned into a host of windows viruses with-no-problems.
In the meantime the 'virus developers' are working on expanding the functionality.
