Ya Linux is virus free OS, How?? Answer: Linux OS Extracted files and folders are kept hidden which cannot be accessed by viruses. Now what are Viruses?? Viruses are the files which carry the path-name of the WINDOWS FOLDER present in Windows OS where all the functional .(DOT)dll files are stored. Once these .dll files get corrupted then the PC starts behaving like a mad bull. So, these .dll kind (not the same format files) of files are also their in Linux OS but they are kept hidden, as a result the virus path cannot find them. Thus, no damage but still the files stored by the user on a Linux machine get corrupted.
ls -a will show all the hidden files that begin with a dot "."
Unix / Linux are both file based operating systems. The majority of configuration can be amended by system configuration files, although as the systems have developed more and more of this is automated and hidden from the user. User configuration files will normally reside under the /etc directory.
System files are files the operating system needs to function (and they may be hidden). Hidden files are those files that are not displayed when you show a directory listing. A file can be both a system file and a hidden file, but a hidden file does not have to be a system file, nor does a system file need to be hidden.

There's actually no such thing as a "hidden" file or folder in Linux. In Windows, files and folders are hidden by setting a file attribute on them, and is used to prevent novice users from viewing or modifying them. In Linux, a file or folder can be "hidden" from most shells and file managers by simply prefixing a "." in front of the name (.settings, for instance). A simple 'View > Show hidden files' or "ls -a" is all it takes to list them. The purpose is thus purely for cosmetic / organizational purposes.
