As computer technology advances,
so do the applications that we often use for our tasks. However, they are
not the only evolving computer technologies. In this direction we also
find that viruses have advanced by leaps and bounds ,
being less and less easy to detect them, as well as the ways in which they techsupportreviews can
access our data and documents that we have stored on the computer.
That is why, regardless of the
operating system that we use on our PC, it is essential that we have a
good antivirus installed on the device , and
well updated with the latest definitions. With this we will ensure that we
can be a little calmer.
In this sense,
although it may seem a simple thing to explain to another user what an
antivirus is and the reasons why it should be used, the truth is that most do
not use antivirus as it is due. An antivirus in reality is a very complex
security tool, both in its operation and in its development.
Perhaps the fact of
being very simple to use, that is to say that we do not have to do anything to
operate it, makes many users think that it is software that is installed on our
system and that it protects us from the viruses that are out there, nothing
more, which at one point is true, but there are other nuances of antivirus that
if we do not know, can complicate our lives, but instead if we understand
how they work and what are the different types of antivirus that exist ,
we can get away with any problem that we may have in the case of being infected
with viruses. We can begin to understand all this below.
Antiviruses are
computer programs whose main objective is to protect us from the computer
threats to which we are exposed when we use the computer to carry out our
tasks. These antivirus programs keep all kinds of threats at bay, such
as viruses, Trojan horses, worms and other problems that tend to lurk
to infect our computers on websites, programs and storage units.
To keep us safe from dangers and
threats, an antivirus app analyzes in real time
the operations we carry out with our computer, trying to
identify if the files we download or store contain portions of embedded code,
called "Signatures", that
identify them with any of the known virus codes.
Every known virus has an
identifiable code pattern, giving each threat the appropriate identity. This
code is called " Signature", and
we could say that it is the DNA of the virus. If the antivirus
identifies a signature in a file that is compatible with any of the signatures
it has stored, it will immediately take measures to
prevent it from spreading.
That
is why it is so important that the antivirus is
up-to-date, since if it is, the bank with hundreds of
thousands of virus signatures it contains will also be up-to-date, which offers
us better chances of being protected.
It should be noted that although antivirus
protection is carried out in real time, the truth is that we can also
analyze our system whenever we want, which gives us a wide degree of security,
especially if we are not the only users of the computer.
Whoever has never
encountered a virus, which is quite unlikely, is unaware that these computer
threats can create quite complicated problems, such as loss of data, corruption
of the information we have stored, and poor computer performance, among other
problems, but there is no doubt that the most dangerous of all the problems
that encountering a virus can cause us is the theft of our confidential
information such as credit card numbers and other sensitive information
that under no point of view can not fall in strange hands.
These problems
caused by viruses often cannot be solved except by restoring the system or
formatting the disk, both solutions that in most cases are impossible to
implement.
That is why having
an antivirus installed on the system, but also well updated, as well as
having safe browsing habits, that is, not getting anywhere and opening any file
that falls into our hands, are more than important points when to be sure.
