- Unix-based operating systems, like Ubuntu and Mac OSX, have never had the pervasive virus infections experienced by Windows users.
- One reason is the way Linux systems, like Ubuntu, handle
file permissions
.
- The system of
file permissions
makes it very, very difficult for a virus to get established.
- In total there have been approximately 50
viruses
targeted at Linux-based operating systems.
- By comparison there are over 120,000
viruses
that currently target Windows-based computers.
- Ubuntu does not let everyone be the Administrator which is a key security flaw in Windows systems.

naturally resistant to viruses
in part because hackers don't target it.
- While Ubuntu comes with lots of software anti-virus software is not included.

One of the many benefits of
Ubuntu Linux is that it
requires far less system resources
than say Windows Vista. That means that Ubuntu can run even on computers that are much older. Ubuntu doesn't need as much RAM, doesn't need as fast a processor, and doesn't eat up as much disk space.

One of the reasons that
and other Linux distributions are so secure and safe is because problems are found and fixed so quickly. If there's a
security flaw
it's discovered and patched before anyone really has time to take advantage of it. That's a benefit of being lean and mean. With frequent updates you can
keep your software and your system running smoothly
.
