While it is theoretically possible to infect a Unix executable with a virus, such things are almost never seen in the wild because the Unix design blocks them from propagating. Contrast that with the virus sewer that Windows users swim in every day. Yuck!Those who think that Unix is free from virus problems should read more.
As he said, it is /theoretically/ possible... but note that the theory requires that a user not just be ignorant, but to also intentionally make an effort to assist.
Which is to say, those who think Unix could ever have the problems that Windows does with security, should read not only more, but *deeper*. Get past the headlines, the FUD, and find out what the facts are.
Unfortunately, as more people move to variations on the Unix theme, more people with less experience will be using it, and more inexperienced people will come to operate in the root, and will be exposed to exactly the same environment as Windows users. You will see the number of virus infestations increase. This is already happening.
Absolutely wrong!
Unix does *not* provide "exactly the same environment as Windows".
There are many inherent differences. There will *never* be the same trouble with virus infestations and it is *not* already happening.
Remember, when the stream is polluted, it reaches even the small 'tidal' pools when the water gets high enough.
The fundamental differences are huge. Small things that most people simply do not understand the significance of make all the difference. For example, the GUI system for Windows is built into the kernel, which was necessary to provide adequate speed. That is *inherently* the wrong thing to do.

A new worm that attacks
Linux systems and exploits several vulnerabilities in the operating system has been reported, and security firms are urging caution among users.
The worm has been dubbed "Lupper" by antivirus firm McAfee and "Plupii" by Symantec (Nasdaq: SYMC - news). Threat levels range from low to medium risk among security companies, mainly because the worm has not been distributed widely.
Although its threat rating is low, the worm is being watched for its potential to hurt Linux systems. It installs a backdoor on infected servers, which then can be exploited to create a network of systems that can launch attacks on other computers.
Just a clip from a recent article. Such things DO happen. Until I retired I worked with AIX servers, (about 200 of them), and the same precautions were in effect for them as for the 40 or so Windows servers we used. The main difference was that when the Windows servers had problems, it was an easy fix. The AIX servers and UNIX servers were usually down for several days while they were researched and repaired.
Never underestimate the opposition. The bad guys often know more about the OS than the good guys.
