That's correct. There is av software available for linux, such
as clamav, or avg, however they are only intended to catch
windows viruses, so linux can be used as a mail/file server for
the windows systems.

How much of Linux's immunity to the above is inherent in the OS
and how much is because Linux boxes are a small percentage of the
total and the Bad Guys just are not targeting them?

It's definitely both. With m$, modules will normally be loaded
in the same order, on many systems. If an attacker can figure
out a buffer overflow in one module, that overwrites the next
module, and then transfer control to the overwritten second
module, that attack will work on all similar windows systems.

Most linux distributions use a randomizer that select which
modules will go where, so you'll find very few, with the modules
loaded in the same physical order. Even on the same computer,
after a reboot, the order may change.

Most linux distributions also strongly discourage users from
running applications, such as web browsers, with the equivalent
of an administrators account. Some don't even allow it, until
the user figures out how to assign a password to the root account.

The file system and network security have always been in the
kernel, rather then being added on later.

When a bug is found in linux, the updates tend to happen much
faster.

Dns poisoning is easy to avoid by running your own name server.
All it takes to do that, is to run one command to install the
server, one to start it (or reboot), and alter one setting
to get all network accessing programs to use it. Changing
that setting can be done by editing one text file, or, with
most distributions, a gui is a available that will edit the
file for you.

For users who are afraid linux will be to complicated for them,
they can always use a Mac, which is based on bsd linux.

It's a mix of factors, hard to say which is most important.

AIUI, Unix/Linux's system of permissions makes it harder to write
malware to infect those OSs. But in principle it's possible. There is no
such thing as a 100% secure OS. An OS is essentially a system of
requests for services, and requests can be intercepted. That's where
malware starts its attack.

Windows also has levels of permission, but for convenience sake they are
not rigorously enforced. Eg, you can boot without supplying a password.
Also, for various reasons, many people hate MS, and so most of the
malware effort goes into attacking Windows. The fact that banks, etc,
use Windows is also a motive: malware is lucrative.

Also, all Linuxes (Linuces?) require that you set up a user and password
when you install them, even if there is only one user. You can't boot
without your password, and you can't install software without supplying
the admin (superuser) password. This adds a layer of security: malware
would have to supply the admin password in order to install itself, but
that password is not in the user's keychain, so the malware would have
to get to the admin level of permissions to get the password, which it
can't do without a password. Nice catch-22. That's how I understand it,
anyhow.

The rigorously enforced sytem of permissions is IMO the only real
advantage of Linux. I think Windows 7 should use the same system of
layered permissions. Might annoy some people who want to just turn on
the machine, but there is no reason to let fools' desires for
convenience endanger us all.

OO is far more functional the M$-Office, and is most definitely NOT a clone
because it provides all the functionality, and then some..

For someone who steadfastly denies using OO, your opinion about it is
worthless.

You've obviously never used http://sourceforge.net if you hold such an
ignorant opinion, but that's in keeping with the rest of your mindless
diatribe.

Yeah, crawl back in your own arsehole.
