A virus that would be processed *by the operating system* is just an 
executable program.  It would be extremely difficult -- "impossible" is a 
word we all try to avoid -- to detect, before running a program, whether it 
replicates itself and/or causes harmful side effects.  That is the job of 
anti-virus software.  And Microsoft is now finding itself in legal trouble 
for bundling "extras" like anti-virus software into their operating systems 
and thereby driving specialized companies out of business.

Both of the systems I use run Microsoft OS's (Windows 95 (!) at home and 2000 
at work), and yet I almost never get affected by these viruses.  At home I 
use CompuServe 5.0, and at work I use Lotus cc:Mail 8.5.  Neither of these 
e-mail clients will download, let alone execute, any attachment (including a 
virus) without user intervention.  The gatekeeper for e-mail viruses is the 
e-mail client, not the operating system.

As Clive Hohberger said, Microsoft Outlook is the preferred target for e-mail 
viruses, not only because it is the "biggest and most symbolic target around" 
but also because it is the closest thing there is to a "standard" e-mail 
client.  Imagine writing an e-mail virus that sent itself to everyone in your 
CompuServe address book, or your cc:Mail address book.  That would be like 
crashing an airplane into a dollhouse.
