if you MUST use a PROFESSIONAL security perpetration testing operating system
install Kali 1.0.5

designed BY SECURITY PROFESSIONALS
for use BY SECURITY PROFESSIONALS in penetration testing

--- to quote ---
As the distribution developers, one would likely expect us to recommend that everyone use Kali Linux. The fact of the matter is however, that Kali is a Linux distribution specifically geared towards professional penetration testing and security auditing and as such, it is NOT a recommended distribution for those unfamiliar with Linux.
In addition, misuse of security tools within your network, particularly without permission, may cause irreparable damage and result in significant consequences.
If you are looking for a Linux distribution to learn the basics of Linux and need a good starting point, Kali Linux is not the ideal distribution for you. You may want to begin with Ubuntu or Debian instead.
