VERY wrong...  

First of all, you won't get word to run on WINE because WINE handles 
only standard APIs, not the secret ones that Microsoft uses, which gives 
word and its macro facility DIRECT access to the Windows kernel.

Crossover only emulates the access, certainly gives no access to the 
linux-kernel because it has only the privileges of the user running 
it...  And unless you are running as root, you CAN'T WRITE TO /bin 
/usr/bin or anything else sitting in your executable path except perhaps 
your home directory.  You might get a virus but
it couldn't propagate.

EVEN IF you were able to run as root (and deal with the poison red 
screen), and you were running Word, and you had a macro virus, it 
couldn't do very much because it isn't the windows kernel.  The most 
likely result would be a segfault/kernel oops or a message about 
privilege violation.

True, the linux kernel has no anti-virus features.  They aren't needed. 
 viruses are theoretically possible, and a few have been written, but 
they can't propagate, so they remain academic curiosities.  Worms are 
theoretically possible, and a few have been written and they have played 
nasty games with systems that didn't stay updated (Yes, you can update 
easily without rebooting), but usually those exploits come out about 6 
months after the fix is available.
