Types
of Antivirus & Increasing its Effectiveness
Nowadays
no one doubts the importance of having a reliable and updated antivirus that protects
your computer from possible attacks, but depending on what type of
antivirus you have installed on your computer, you will have better or
worse security.
In
this article you will verify that there are many types of antivirus and
to show you, we are going to classify them according to different criteria such
as: their purpose, according to whether they are created to meet a specific
objective, according to how they are executed and according to their brand.
What types of antivirus are there?
Types
of antivirus according to their purpose
·
Preventive
antivirus
They are characterized because they
analyze the input and output of all the data on your computer in order to
intercept possible threats, anticipating the infection of the computer by
malicious programs. They are installed in the internal memory of the computer
and can sometimes slow down its operation.
·
Antivirus identifiers
As their name suggests, they are
antivirus that scan your computer's operating system in order to identify
possible viruses that exist on it. They track byte sequences of specific
codes and try to identify strange behavior or out-of-the-ordinary patterns
within existing programs.
·
Decontaminating
antivirus
When the virus is already identified
on our computer, the decontaminator type antivirus is in charge of eliminating
this infection. It has some similar functions to identifier antivirus.
Types
of antivirus according to your specific objective
Not
all antivirus are
designed to fight the same type of virus, so it is important that you identify
the types of antivirus that exist according to their specific objective:
·
Firewall
or firewall
The firewall (firewall in Spanish) controls the entry and exit of data from your computer and blocks "like a wall" all that activity that is doubtful to it . Act preventively. Currently we can identify 3 different types of firewall: proxy servers, network layer (or packet) filters, and application layer firewalls.
·
Antipop-up
This is a very simple antivirus that is only
responsible for preventing some websites from automatically opening emerging
advantages that may be annoying when browsing the Internet.
·
Antispyware
or antispyware
This antivirus has the objective
of detecting and eliminating spy programs that have been installed on
our computer without our consent. The purpose of these malicious and
silent spy programs is to collect information about the user (passwords,
browsing habits, etc.) to pass it on illegally to third parties.
·
Antispam
Its specific objective is to identify
emails of dubious origin and send them directly to the spam
tray. Virtually all email service providers, such as Gmail, Hotmail,
Yahoo, etc. they have their own antispam systems.
·
Antimalware
The antimalware are designed
to analyze, detect, prevent and remove malicious software on our computers, i.e.
malware. It is not a simple tool (as an anti-pop-up can be), but it is a
more complete program that normally already incorporates several of the
anti-virus functions mentioned in this list.
Types of antivirus according to
its execution
According
to this classification we can find:
·
Online
antivirus and offline antivirus
Those entire antiviruses that do not
need to be installed on your computer, but that act only through the Internet
are classified as online antivirus. If they do not require the Internet to
be executable, they are offline antivirus.
·
Passive
antivirus and active antivirus
If the antivirus only acts when the
user requests it, then we are talking about a passive antivirus. On the
contrary, if the antivirus acts autonomously without the need for the user to
give it a specific order, then we are talking about an active type antivirus.
There
are many security programs and tools that we can use on our devices to protect
our systems and privacy. But undoubtedly the most popular are
antivirus. There are free and paid ones. They are available for all
types of platforms and operating systems. Some, of course, may work better
than others. Therefore, this issue must be taken seriously when choosing
an option. In this article we are going to explain how an antivirus works and what
we can do to make it work better.
How an antivirus
works
As
we know, an antivirus
has the main objective of detecting and eliminating possible threats . There
are many types of viruses, Trojans and other types of malware that can
compromise the proper functioning of the system. What this type of
software does is protect us, prevent information theft and prevent the entry of
malicious programs.
Basically
we can say that an antivirus uses a database to detect
malware. A signature database, which is how it is known to identify
threats, offered by the manufacturer. This is what helps prevent the entry
of viruses, Trojans and other known threats.
What
about this? As we can suspect, if you try to enter a threat that is not
available in that database, it will not be detected by the antivirus. For
this reason, not all antivirus
are the same, since it depends mainly on its database.
Luckily
the antivirus has been improving over time. They no longer require as much
of a database. Modern antivirus products have a more efficient active
protection capable of detecting threats that do not yet have a signature
and, therefore, will not be in the database.
In
this case, what it does is use a series of algorithms that determine whether or
not a file may represent a threat. It takes into account things like
whether you can edit the registry or remotely connect to another computer.
How to make antivirus
more effective
We
have basically seen how an antivirus works. However, they do not always
act in the correct way and not all of them are capable of protecting us in the
same way. The first thing to keep in mind when trying to make your antivirus work better is
to always keep it updated . So we can have a database that can
detect the latest threats and also has the new functions to protect us.
On
the other hand, keep in mind that free antivirus programs usually
lack all functions. Some only detect and cannot eliminate the problem, for
example. It is important that in this sense we choose an antivirus with
guarantees. We leave you an article with the best antivirus for Windows 10
of the moment.
It
is also important not to have more than one antivirus installed. The
reason is because it could cause compatibility problems and affect performance.
In short, an antivirus
is a fundamental piece to maintain security. It is important to take care
of it and always keep it updated
