the thing u just understood was called file permission system in UNIX-like Operating systems.this is the reason why u simply cant access some directories,files.
and that itself prevents Viruses,spywares to be able to run on Linux.so no need for anti-virus,anti-spyware,anti-anything<add tag>
Differences between operating systems

Unix-like and otherwise POSIX-compliant systems, including Linux-based systems and Mac OS X (through version 10.3), have a simple system for managing individual file permissions. POSIX also specifies a system of access control lists, but it is only implemented by certain file systems and operating systems.
DOS variants (including the Microsoft products MS-DOS, Windows 95, Windows 98, and Windows Me) do not have permissions. There is a "read-only" attribute that can be set or unset on a file by any user or program.
Microsoft Windows NT and its derivatives (including Windows 2000 and Windows XP), as well as VMS and OpenVMS use access control lists (ACLs) to administer a more complex and varied set of permissions.
Classic Mac OSes are similar to DOS variants and DOS based Windows: they do not support permissions, but only a "Protected" file attribute.
Mac OS X, beginning with version 10.4 ("Tiger"), supports both the use of complex access control lists (ACLs) and the traditional POSIX-compliant Unix-like simple system for managing individual file permissions. It also still supports the Mac OS Classic's "Protected" attribute.
