<p class="p">If you are used to Windows or Mac OS, you are probably also used to having
80
anti-virus software running all of the time. Anti-virus software runs in the
81
background, constantly checking for computer viruses that might find their
82
way onto your computer and cause problems.</p>
83
<p class="p">Anti-virus software does exist for Linux, but you probably don’t need to
84
use it. Viruses that affect Linux are still very rare. Some argue that this
85
is because Linux is not as widely used as other operating systems, so no one
86
writes viruses for it. Others argue that Linux is intrinsically more secure,
87
and security problems that viruses could make use of are fixed very
89
<p class="p">Whatever the reason, Linux viruses are so rare that you don’t really need
90
to worry about them at the moment.</p>
91
<p class="p">If you want to be extra-safe, or if you want to check for viruses in files
92
that you are passing between yourself and people using Windows and Mac OS,
93
you can still install anti-virus software. Check in the software installer or
94
search online; a number of applications are available.</p>
