THE VIRUS IN THE PC AND THE HUMAN BEING
As all realize the computer was created a “similarity”of
to be human it is to say while a person has brain the computer has CPU
(Central unit of process), while a person has memory,
the PC has RAM, among others. Thus also the virus computer science is created
to similarity of the virus of a human
1. Capacity to reproduce automatically
In the human being a virus one reproduces in our organism in surprising
form, infecting or mutando to the good cells of our
with the purpose of becoming but hard or reproducing
In the Computer, for example a virus type "Worm" (W32)
it creates hundreds or thousands of copies of if same in the hard disk.
It infects to the archives of the operating system or
they are mutan with them (they copy part of its code) so that whenever the operating system executes
the computer becomes infected automatically.
2. Migrate towards other elements
In the human being it is transported by means of the
cleanliness equipment, in order to invade other organisms
(persons). In the Computer:It infects diskettes, CDs, the
in order to infect other computers.
3. Resistance to vaccines
In the human being as it has been said already
they are mutan with other cells of our organism or they change its cellular code constantly
(like the virus of VIH) in order to confuse to our defenses or
In the Computer: Memory resident
in order to avoid to be eliminated by the antivirus or it is encapsulated to deceive
4. Destruction or harmful action
: In the human being it can cause partial collapse or
total of our functions or in worse of the cases the death.
In the Computer: Elimination of data,
information robbery or in the worse one of the cases burned of the
THE VIRUS AND ANTIVIRUS
An erroneous myth in the users exists who are:
the companies antivirus create the virus, then this can be described like one
it is to say any company antivirus has personnel enabled like creating
but this would be a serious offense that it is suffered by the law and it would go against the principles of these companies
and of its personnel, it is because a particular clinic created virus to have but
ill, ¿would exist so clinical ?
¿Why the programmers create virus?
This is the question that becomes almost all the
"¿they who win making virus?",
everything is not absolutely clear, some virus is created by the technological challenge
create a threat that is unique, nondetectable, or simply devastating for a possible
victim. Nevertheless, he is debatable that most of the people creates virus by
the creative hope that the virus propagates in such a way that it makes it famous
(although single to his Nick, since obvious it cannot reveal its true name
: for example "Created by xXXx"). Other experts say "they want to develop their creativity of programming"
putting a label to them of "investigation" to its
¿How they are
The main means of transport are
Diskettes or another removible storage media
Computer science networks
(PC with infected virus to another one inside a network ).
Messages of electronic mail
(with annexed archives).
Lowered Software of Internet.
Visiting certain pages Web
(xxx, games on line, etc).
¿How if my computer this with virus?
Many virus announces with certain
sounds, messages, etc, others are hidden of the user in order to facilitate its reproduction and infection in the
Between the main symptoms we have:
Retardations when loading a program
Slower operation of the
Defective hard disk sectors
Unusual messages of error.
Strange activity in the
Changes in the characteristics of the programs
It is possible to mention that some software nonmalicious
they can cause some of these characteristics involuntarily, because of being badly
¿That damages can cause?
The damages caused by the virus are
they go from the burned one of the hard disk and the board until one it bothers
We have classified them of the following way:
Modification, elimination of programs and archives
Cause that the system works slowly
Robbery of confidential
Saturation of a network
End the free space of the hard disk
Erasure of BIOS
(general configuration of the PC )
Burned of the processor by false information of the temperature censor.
Breakage of the rigid disk when doing to read repeatedly
¿How to come up to us?
It is recommendable to have
: 1 antivirus, 1 antispy, 1 firewall (optional), and the Patches of
Microsoft Corp. The antivirus
it will eliminate the virus, the antispy
the spy (spywares), the firewall
avoided the exit or the entrance of any application or malicious file,
of Microsoft that it will repair the errors that it has
Windows, this is very crucial since if not parcha its operating system,
although it has installed all the antivirus of the market, the system can run risk of becoming infected.
"¿Of which it is worth to protect the fore doors of a house with the best watchmen and guardians if the open windows are had wide?.
The virus is a thief who enters the dark at night his house or it calls to account and where the antivirus is the guardian,
the firewall is the door, the patches are the windows". If You it wants to stay safe must close well
the "Door", to have the best one "Guardian " and to close all
The greater catastrophe than can cause a virus in a company,
is the lost, alteration, elimination of data (information),
many of these are lost million dollars because of this reason.
