Computer viruses
The computer viruses are program files that are capable of
reproducing its special code. It also attaches the code to the
files without the user’s knowledge. Since the code is attached,
the newly amended codes run as the rest of the programs run.
Also, these programs search out for other programs to which
they are not attached. Consequently, the virus attacks files that
are saved on the computer’s hard disk as well as the external
devices. For example, the virus attacks a flash disk once
inserted into the computer. Interestingly, these computer viruses
are a direct result of a person that intentionally designs them
(Ferbrache, 2012). They are tested to ensure that they produce
the desired effects. In summary, a computer virus is a program
file that attached itself and spread through other computer
programs hence damages their functions, but can be prevented.
Characteristics of Computer Viruses
The virus replicates itself once it is created and distributed. It
also attaches itself to program files as it spreads whenever the
program is executed. The infected files then repeat the
duplication process when they are run. On the other hand, there
are other programs that are created only to spread the virus
when specific commands are made hence activate the spread. As
a result, these viruses are known to capture a portion of the
system function in a computer for them to distinguish their

Prevention of computer viruses
Prevention of the computer viruses is significant because they
interfere with the normal functions of the computer programs. A
computer user needs to protect the machine and maintain data
security. Usually, an individual can avoid the viruses by
