Mac and Linux viruses?
Lets put this into language that everyone can understand. As the old
saying goes, a picture is worth a thousand words, so let's use some
analogies to illustrate the point. For the purposes of this discussion, let's assume that all viruses are
"sexually transmitted". Next, let us also assume that restricting file
and system access permissions in the operating system is like wearing a
condom, and communicating on the Internet is like having sex (pretty
good analogies if I don't say so myself). Windows systems are set up by default to allow users full access to the
entire system, which is to say that the operating system is NOT wearing
a condom. This is the equivalent of having unprotected sex at all times
while on the Internet. As a result, when viruses and other malicious
code gets into the computer, the malicious code also has unrestricted
access to the entire system. Windows users are therefore encouraged to get "vaccinated" by using
anti-virus software to protect them against all the "known" viruses (I
say "known" because, like real vaccines, most anti-virus software is
only effective against “known” viruses). So,
Windows PC's are having unprotected sex ALL the time, even though there
is no protection against new viruses (until a new vaccine comes out
anyway). In addition, there is also malicious code (ie: rootkits) that
can be completely undetectable. Mac, Linux and other Unix based systems come with condoms
pre-installed. Which is to say that they have restrictive file and
access permissions set up by default, so if any malicious code does
manage to find it's way in, it will have the same restrictive file and
access permissions as the user. Because the operating system is wearing
the condom, the worst case scenario is that the user's own files might
get “hosed”. The malicious code does NOT have
access to vital system files like it does in Windows (ie: the system
registry). Is it possible for Windows to wear a condom or for Mac/Linux/Unix to
operate without one? Well, yes it is, but most systems do not switch
from the default setup because the vendor(s) of most operating
system(s) make it difficult for the average user to do so. So, Mac/Linux/Unix systems have condoms on ALL the time and Windows
systems NEVER wear them, even though there are tens of thousands of
viruses in the wild, and over 99% of them ONLY target Windows systems.
Less than 1% target Mac/Linux/Unix systems. There are never any guarantees in the world of Internet security.
Security is NOT a product, it's a PROCESS. It just so happens that
Microsoft got the process wrong. Security in Windows was an
afterthought, so they are "reactive". Security in Mac/Linux/Unix based
systems was built-in from the get-go, so they they are "proactive".
Huge difference! Windows is not necessarily a “bad” operating system
(at least I don't think so), but they certainly could have outfitted
Windows with condoms on by default instead of leaving it to end users
to put them on. I think that was a very bad decision. I hear Vista is
supposed to be more “Unix-like”. We'll have to wait
and see. Let the “experts” put that in their pipe and smoke it! |

When cows grow wings and learn how to fly
Mr Parris,
With all due respect Sir, I said "worst case scenario".
I rescue Windows desktop PC's from malware on almost a daily basis. Many of these machines need a format and reinstall, as the operating systems (Windows) become so corrupted (not user data), that they are beyond the ability to boot (even in 'safe mode').
See: http://www.eweek.com/article2/0,1895,1945782,00.asp
Recovering user personal data is normally not a problem, ie: boot from Linux 'LiveCD', mount NTFS partition, recover data.
In the early days of malware it was mostly malicious. By that I mean, the code seemed to be written by delinquents who got a thrill out of trashing people's PC's (deleting data files, etc). Today that is generally not the case. Today's malware writers are doing it for financial gain, ie: stealing personal information, hijacking PC's and turning them into SPAM bots or using them for DDOS attacks.
I will agree with you that virtually anything is "possible", but does that mean it's probable? I suppose one could say it's "possible" that one day cows will grow wings and learn to fly, but is this probable? Is it really worth getting concerned about? This discussion is like debating the relative safety of traveling by airliner vs. by automobile. There is simply no comparison, however tell that to people who are scared to fly because of endless media reports about plane crashes.
As I write this, there are literally tens of thousands of hijacked PC's all over the world the criminals have turned into "bot nets". They rent them out on the black market for illegal activities. Every last one of these PC's are Windows based.
Is it "possible" that one or more might be Mac/Linux/Unix based some day? Sure, it is .... when cows grow wings and learn how to fly.

It's called having a vested interest. There is now a vested interest on both sides to not sort Windows out as this would in turn lead to loss of revenue from technical support and a loss of revenue from products designed and sold to "fix windows". (Anyone who tells you MS can't sort this is lying. No one on earth has the wealth available to Microsoft, if they're not prepared to use it to sort out their own products but would rather spend it bending the law, crushing the opposition and spreading lies then they deserve all that's coming to them).
The other side of this is the constant wittering from MS sympathisers how the only reason Linux isn't likewise afflicted is is down to Linux being used by about 10 people worlwide so "who will bother attacking it?". Implication being that it would be easy to attack were the numbers to provide sufficient motivation. Well I've looked at the list of companies that run Linux and there are some large companies there and the news is eerily silent of news about large companies being infected by virii targeted at Linux.
Don't believe the hype!
