Why is the Unix operating system virus free?

First of all, Unix (and even Linux) is NOT virus free.

Although rare, there are viruses for such systems.

One of the primary reasons that Unix / Linux do not get as many

viruses is that the ability of different users is limited.

Non-technical users will be restricted in their ability to install,

run, or modify software. More experienced users will usually be

given more privileges. Without inexperienced users installing

software at a whim, over 90 % of the threat of viruses and malware

is removed.

Linux is even further protected against viruses because Linux is

by nature a heterogeneous platform. To be effective, the program

would have to be capable of affecting multiple versions of the

kernel, and use exploits in a variety of programs.
