That is completely correct, there are major difference between *nix operating system and Windows. not even on the technical leve but on the quality of deisgn and approach

Dues to the learning curve of the OS, the users were more "enlightened" than the common computer user, but now these are more wide spread and the common user will be using them. The conspiracy theory people say that Antivirus companies are the ones making most of the viruses so that they have a product to sell, well there is a market out there just waiting to be tapped. Norton AV for Mac is on the shelves even though there is only really 1 documented virus, and people buy it.

You are, of course, making the classic mistake of not understanding
security on computer operating systems. Popularity has little to do with
how vulnerable a system is.
Fact: Windows XP is about 12 years old, Vista/Windows 7 maybe 5. Unix
is 40+ years old.
Face: Unix was designed for a mult-user, multi-processing environment,
Windows was designed for a single user, single application at a time
environment, it has had mult-user and multi-processing added on to it.
Thus, most everything that can affect Windows today was probably seen
and corrected on the architectural level decades ago in Unix. Even the
simplest thing of making the user work in a non-privileged workspace is
one of the basic things that Unix has done for decades, while it is a
relatively new idea in Windows. Thus, if you compromise the workspace,
you don't compromise the system.
Next, you have the fact that to make things really fast in Windows, you
have graphics primitives in the kernel. This means that to compromise
the entire system, all you need to do is compromise a graphics
routine...and as almost everything is graphical in Windows...compromise
the Browser, you can own the system...compromise the mail reader, you
can own the system...compromise an editor you can own the
system...compromise an ERROR MESSAGE, and you can own the system.
With Unix, very few things can access the kernel. If you compromise the
Browser, you may compromise the user's workspace, but the system remains
compromised.
Generally, in Windows it's a single set to compromise the entire
system...on Unix, it takes usually two more more steps, first you must
compromise the userspace, then you must compromise the kernel.
Ultimately, it takes a lot more work to compromise a Unix system than a
Windows system. And that makes Unix and systems derived from Unix
inherently more secure than Windows.
