I would like to point out, in the gentlest of manners, that is absolutely
untrue. In fact, one of the earliest known bits of effective malware, the
Morris worm, attacked Unix systems. (Of course you know that Linux is a
lineal descendant of Unix--in fact, there is less difference between Linux
and, say, BSD Unix than there was between various Unix variants in the late
'80s.)
ALL software has bugs and vulnerabilities. Unix and Linux tend to have
fewer successfully exploited ones than Windows for numerous reasons, some
historical--Unixoid systems have had the concepts of multi-user support and
separated privileged access baked in from the get-go, while it evolved into
Windows--some demographic--most Unixoid systems are installed and
maintained by professionals or, if not pros, people who are generally more
technologically savvy than the majority of the millions of Windows users,
making the Unix/Linux systems "harder" targets--and some sheer volume;
there are one hellova lot of Windows systems, ranging all the way back to
Windows 2000 and even earlier, still available for attack.
Finally, as others have pointed out, it's a multi-OS world out here, and
many Unix/Linux systems are being used as hypervisors for guest operating
systems--most assuredly including Windows--or, probably more often, as
servers for Windows networks.
Sincerely,
