Who uses Linux, besides being surely a fan of open source, is also one who is attentive to the security of his computer. In fact, no one will ever be able to dispute that Linux is the safest operating system (also because, being little used and free, no hacker would make viruses to hit Linux). Linux has a great reputation on security, so much so that in hacker competitions it is always the most difficult to violate.
Anyone who wants to can take a Linux system to use on any computer, perhaps in a USB stick or on a CD, to avoid, in a certain way, that traces remain of its use and internet browsing .

First of all, I want to say that Linux distributions such as Ubuntu and Fedora (see how to install Linux Fedora or Ubuntu on a USB stick) are absolutely safe and can be configured to surf anonymously by installing anonymous browsing programs such as TOR or with OpenPGP mail clients such as Hushmail (see how to send encrypted emails and password protected messages).
Those who already use Ubuntu or Fedora can install SELinux, a package that creates a sandbox where everything that is done is isolated from the computer and kept in a separate environment.
For more information on the sandbox you can read the article on how to protect Windows from changes, assign permissions and do tests without risk
However, if you want to try something more delicious, safer, more protected and absolutely anonymous, you can use a different Linux distro like, for example, these two:
1) Tails is a real incognito live system, which makes it possible to cover everything you do on your computer in a barrier of absolute security, without leaving any trace.
Live means that you can burn the ISO image to a CD and start the PC from the disk instead of from the hard disk by loading Windows.
The distribution is based on Debian, known for its great stability and security.
Tails completely erases any trace of what is done on the used computer after you turn it off or restart it, without saving anything.
Tails comes with some software to satisfy every need: Firefox browser (the modified Iceweasel version) is configured to use the Tor network by force.
The browser also includes other extensions to make browsing as safe as possible with the HTTPS Everywhere and NoScript plugins.
Tails also comes with Claws Mail which supports encrypted emails via OpenPGP, Pidgin with support for OTR encrypted chat and editing tools such as GIMP and OpenOffice.
2) Privatix Linux very similar to Tails even if with fewer applications inside it
3) Liberte Linux is a nice distro to use, not very simple.
4) Trusted End Node Security (TENS), formerly LPS, is a Linux portable distribution that is being developed by the US Air Force, and appears to be the only distribution that is used by the American military.
This is not an isolated case, other countries produce their own Linux distribution, such as Red Flag in China and Pardus in Turkey.
This distribution has a more minimalist approach, with a desktop similar to that of Windows XP, with few programs including Firefox and other additional tools.
It also has a data encryption tool and is all oriented towards complete user privacy.
LPS is also a Live operating system that can be used without leaving a trace and without being able to save anything.
There are also several other distributions for security and to keep what you do on the computer private.
Also noteworthy is the famous BackTrack distribution which serves, rather than to keep the use private, to take advantage of hacking tools and network security.
