> What is PERCEIVED as virus immunity is just that your particular machine and OS combination has not yet been targeted. Those evil beings that write viruses are looking for the most ''bang for the buck'' and target the operating systems most commonly used. That just happens to be ''Wintel'' systems. Apple computers are a much smaller segment of the computer users with Linux (I think) coming in about third.
It is a fact that Linux and other UNIX-like operating systems are architecturally different from Windows and consequently more difficult to attack. To be fair, MS has made great improvements in its products' security over the past three decades, but Windows is still considered easier to attack than Linux. That said, Linux-BASED operating systems such as Chrome and Android have made various compromises that probably adversely affect their security. Still, Chrome has a pretty good reputation as a secure operating system.
> Also, bear in mind that Linux is an open source operating system, and as such is even more vulnerable to hacking and virus attack. To most hackers, it is such a small segment that it just isn't worth the effort to write a virus for it.
It is the general consensus that 'security through obscurity' (the Microsoft approach) is no security at all, because vulnerabilities often exist in proprietary software for years before they're noticed and corrected. On the other hand, open source software is reviewed by different many different developers (thousands of programmers, in the case of the Linux kernel), all looking for potential vulnerabilities. It is simply not true that closed-source software is necessarily more secure than open-source. Some closed source software is secure, some is not. Some open source software is secure, some is not. Linux, and the Linux kernel in particular is considered to be highly secure.
As for market share, it is true that Linux has a small yet significant share of desktops. But on servers, Linux is much more popular. NEARLY ALL web servers, for example, run Linux. It is hardly a 'small segment'.

In the summer of 1995, my father, Russ Goodwin, and I acquired the 1945 Farmall B that my grandfather used as an overseer on a farm in Waynesboro, Georgia. After my grandfather’s death in 1955, J.P. Rollins, son of the landowner, used the tractor. In the winter 1985, while in his possession the engine block cracked and was unrepairable. He had told my father
