Antivirus: programs
whose function is to detect and eliminate computer viruses and other malicious
programs (sometimes called malware).
It is not the intention of this article to go into
technicalities of how antivirus works or anything similar, but to make the user
aware of the importance of something so simple but at the same time with a
significant impact on the security of our PCs.
The importance of updating our software / programs is not
only delegated to the Antivirus
but it is a routine that we should incorporate into any program installed on
the computer whose function is security.
In the particular case of Antivirus, the update is
necessary for the simple fact that one of the tools it has to prevent or detect
the entry of computer viruses in time is the detection through its database.
Basically, what it does is take a piece of code from the
virus in question and incorporate it into its database, so that later, either
through scanning or permanent protection, when a new file is entered or
processed on the computer This will compare that fragment of code available in
the antivirus database with the file that is being used, and if they match, an
alert will immediately appear in our system warning us that a virus has been
found.
The efficiency of this process is closely linked to the
"quality" of the database, let's say that the more records it has,
the broader the spectrum covered by our Antivirus.
Why
are we commenting on this? And what does it have to do with the update?
We comment on it because it has to do with everything.
Because one of the things that is installed in the process
of updating an antivirus, are new records in the Database, let us bear in mind
that new viruses are emerging every day, and existing ones are mutating; so
having an Antivirus software
installed and not updating it is having security only from the moment of
installation backwards. By this I mean that all viruses and / or malicious
programs that emerge (and will) come to light at a later time we will be
defenseless.
That is why we believe it is necessary to insist on this issue,
for the following reasons:
Ø It is
a simple process to carry out, which even the user can do.
Ø Besides
the ease, it is something that only takes a few minutes.
Ø It is
something vital, essential, for the maximum performance of our Antivirus.
Also, we have the option of activating automatic updates in
our Antivirus software,
which, if we want to "forget about it", it would not be a bad idea;
What we would have to take into account is not to put it to update on a
schedule in which intensive use of the pc is made because we would be slowing
down the system, hindering the other tasks that we are doing, although it is
not critical anymore that, in itself, the update process does not usually take
long.
Otherwise, it happens when we scan the pc for viruses, this
if we decide to do it automatically, try to set a time when the computer is not
being used, because exhaustive use is made of the computer since it has to
scour file by file for viruses.
