What are the best free and paid antivirus for all devices? 2020

Sharing is caring!

In this article, I am going to show you the best free and paid antivirus for all the devices.

The growth of computer systems and technology has been immense and thanks to this, a large number of programs have emerged that simplify the day-to-day development of its users. 

However, despite the notable efforts made by law enforcement agencies and software developers, viruses continue to linger on them.

In this way, malicious programs are still a threat to all users, since they can cause damage to their private information, as well as their devices. T

aking into account that, there is still no solution with the ability to eradicate the scourge of malware and its fearsome consequences on computers and devices.

However, despite the fact that there is no definitive repair to this, you can make use of other alternatives that allow you to perform your tasks with relative security and freely browse the Internet. 

Thus, the most effective alternative is the antivirus available for all devices, and then we detail all the information regarding this.

What is an antivirus and how do these computer programs work?

For many years, viruses and malwares, like all threats of this type; They haunt Internet users and can be contracted in different ways, taking into account that they manage to get into your computers or devices in a sophisticated and treacherous way.

But, in order to avoid this, the famous computer antivirus appeared.

In this sense, an antivirus can be defined as a set of programs that show the ability to protect your computer, your mobile, or tablet; for any damage that may be caused by malicious software, program, or application. 

Thus, this name has its origin in the fact that it is a tool designed to combat computer viruses, originally.

However, beyond managing to combat these viruses and eliminate them, antivirus also takes care of the maintenance of operating systems and covers countless functions, today. 

Taking into account that, today, they are advanced solutions with the full power to detect any malware, such as Trojans, worms, keyloggers, adware, spyware, etc.

On the other hand, regarding their operation, antivirus work in the background, reviewing each file that is opened on the computer or device where they are installed. 

Thus, it proceeds to compare these files with a database that contains all types of existing viruses, to find out if there are any of these threats, in a highly efficient way.

In addition to this, antivirus programs also take care of scanning the entire hard drive of computers and, in this way, they are very useful for repairing a computer that is already infected and properly detecting what is the fault.

 What are the most important characteristics that an antivirus program should have?

What are the most important characteristics that an antivirus program should have

Now, despite the infinity of antivirus solutions on the market, not all of them are as effective. 

Therefore, it is necessary to take into account the most relevant characteristics that an antivirus must exhibit when choosing it, so that it can do a good job, detecting and avoiding all the variety of viruses and malware that appear.

Here are the main and most essential features of an antivirus program:

  • Ability to detect and react to a new virus : An optimal antivirus should not be limited only to the detection of some types of malicious programs, that is, it is important that it manages to search for and exterminate any kind of threat that comes your way.
  • Ensure real-time protection : Since computers are online all the time, it is valuable that antivirus programs manage to protect you from any threat in real time and not only when you are the one who orders the action to be taken.
  • Systematic update : Although not all have this function, the truth is that there are already many solutions with the ability to update systematically, in order to provide you with complete and optimal assistance.
  • It must have verification options : Verify that the antivirus you are going to use can be configured to carry out deep and fast verifications at the same time. Additionally, it should offer you options for scanning locations.
  • Minimum memory utilization : In order that the other activities can be executed normally even when the antivirus is running, it is important that the solution in question uses little memory and works in the background without revealing any problem.
  • Email protection : The best virus and malware protection software should be integrated into email management programs, in order to prevent users from being contaminated with threats contained in the messages received.

 Other characteristics of interest

  • Minimal detection of false positives or false viruses.
  • Creation of emergency or rescue discs.
  • Verification of startup and possible changes to the registry of applications.
  • Great disinfection capacity.
  • Alert about a possible infection through the different entry routes, such as: Internet, email, network and / or floppy disks.
  • Presence of different detection and analysis methods.

Is it really best and most useful to use an antivirus? Advantages and disadvantages of doing it

On the other hand, much has been questioned about the use of antivirus on computers and for that reason, users do not know if it is really useful to use this computer security tool or not. 

In the face of this doubt, it should be noted that using an antivirus is currently a great help; although it also depends on the case .

In this sense, if it is a personal computer that is only used by its owner and no other person has access to it, the requirement for antivirus software is not so important . 

Well, it will simply be necessary if the owner’s usage habits request it.

In this way, it will be more relevant for the person to make responsible use of the equipment and avoid infecting the system with malware. 

But, in case you have irresponsible browsing habits and do not take into account certain parameters to stay safe from these threats, installing a virus will be extremely decisive and indispensable.

For its part, it is valuable to note that, if the case is based on a shared computer , the use of an antivirus will be an absolutely essential rule. 

Since not all users will perform the same tasks or have the same knowledge about computer security to prevent virus infection. 

In such a way that, to avoid any risk, the installation of an optimal antivirus is more than useful.


Among other things, to better interpret the utility shown by antivirus software, it is worth specifying what the advantages are, mainly .

Next, the highest value:

  • It ensures protection against viruses and thus, prevents threats such as Trojans, malware and spyware from entering; on your computer or device.
  • It offers protection against identity theft , so it can prevent the illegal use of personal identity to commit crimes.
  • They reveal great comfort , since you will not have to worry about the safety of your equipment. Taking into account that, with the appropriate antivirus activated and working, you will simply receive a notification that will expose that a virus has been detected and will ask you if you want to eliminate it.
  • There are very cheap and even free antivirus solutions . So, they allow you to save money while protecting you.
  • Many antiviruses provide parental control and thanks to this, you can protect the smallest of the house by monitoring how much time they spend online and limiting the downloads or the sites they can visit, for example.


However, the use of an antivirus is not always as effective as it seems and for this reason, it is necessary to know what are the main disadvantages or cons that these types of tools exhibit :

  • Having antivirus software with multiple detection methods installed is not enough. Therefore, these tools do not protect you completely .
  • In various cases, these programs can decrease the performance of your computer or network , since many use a considerable amount of memory on the computer and space on the hard drive, which ends up slowing down the system.
  • Some antivirus software may not employ all existing detection methods, and because of this, reveal limited detection techniques and, as a result, may not be able to locate all threats that access the computer.
  • A large variety of these solutions do not have a real-time analysis , so their operation can be very tedious for users and will not offer complete coverage in terms of security.
  • Several antivirus programs are likely to show errors and point out malicious files when they really are not ; thus showing a terrible operation.

Types of antivirus How are these software classified?

Additionally, it is also opportune to identify which are all the types of antivirus that exist and with it, specify how these computer security tools are classified.

Below, we present each of the types of antivirus, according to various aspects, with their main characteristics :

 According to its category

One of the classifications of antivirus software is based on the category or condition they reveal, which is linked to its way of acting and the site where it is installed :

  • Active antivirus: Despite the fact that this program cannot exercise constant protection, it runs and works according to some kind of action continuously.
  • Passive antivirus: Although it is always installed on the computer, it does not show any operation or permanent protection.
  • Offline antivirus: It is installed on the computer, mainly for its protection and also for the detection of threats and to suppress any malicious application.
  • Online Antivirus: It performs the scans directly from the Internet since it is not installed on the computer. Thus, it is used only to find out if there are any viruses on the computer.

 According to its function

Due to the various functions that these programs can fulfill in their fight to identify and eliminate any computer threat, they are also classified according to their role:

  • Detectors : They are responsible for alerting users to the presence of a known virus. But, it is only the user who can solve the problem to end the present infection.
  • Eliminators-repairers : Their objective is to eliminate threats from the affected parts of the system and in addition to this, they manage to repair the computer to return it to normality.
  • Heuristics : They are a kind of simulator, because they are in charge of faking the execution of programs in order to see how they behave and, from there, they identify suspicious situations.
  • Immunizers : They have the ability to anticipate the entry or attack of any malicious program. Thus, they are in charge of monitoring the execution of the applications, copying the files and formatting the disks.
  • Residents : Its main function is to analyze the softwares from the first moment in which the user accesses it and with it, examines whether the file contains viruses or not.

 According to your specific objective

This classification is based on the specific tools that are part of each antivirus solution, especially in its complete versions to prevent specific threats .

Here are the types that exist:

  • Antimalware : This is a program that has the necessary functions to block and erase any form of existing malware. Bearing in mind that, malwares are malicious programs that infiltrate computers to damage them quickly.
  • Firewall or Firewalls : They are preventive tools that act as a defense wall to block the access of malicious programs to a system. Its most special objective is to control inbound and outbound traffic, as well as stopping all mysterious activities.
  • Antispam : It is defined as a utility used to prevent the arrival of any junk mail in your email inbox and thus sends them to the recycle bin. This type of email is also known as “spam” .
  • Antispyware : They present the ability to detect and suppress spyware that is hidden from your computer, in order to know all the user’s browsing habits and other personal data to proceed to transmit them to an entity not empowered.
  • Antipop-ups : Identify and prevent the execution of pop-up windows that are displayed when you surf the net. Which often hide spyware.

 According to its purpose

Finally, we refer to this category of the types of antivirus that exist. Taking into account that, in this case, the program has certain possibilities to liquidate a certain virus :

  • Antivirus identifiers : As the name implies, they are responsible for identifying threats that can negatively influence the performance of the operating system. Therefore, its functionality consists of exploring this system and examining the byte sequences of the codes linked to dangerous software.
  • Antivirus preventers : Its peculiarity is based on anticipating the infection to prevent the access of a malicious program on the computer. However, since they are stored in the memory of the computer, they can slow down the operation of the same and, therefore, they are not as used.
  • Antivirus decontaminators : They are focused on ending the infection that has caused damage to the computer and for this, they are responsible for eliminating existing viruses to return the system to its natural state.

What is the most powerful and safest antivirus in the world today?

Without a doubt, the best antivirus is the one that provides the most complete functions and truly effective tools with which it manages to guarantee complete security in the system , so that your computer can remain virus-free. But, although most computer security solutions promise this, there are very few antivirus software that truly offer good and complete assistance.

In this sense, although it is not easy to classify a single antivirus as the best among the hundreds of proposals on the market, there is certainly one of them that shows remarkable capacity and today, it can be considered the most optimal antivirus of all .

Thus, it is Windows Defender that has all the tools required to fight viruses and threats, from one of the best virus definition databases and, in addition, in real time.

What is the most powerful and safest antivirus in the world today?

Among other reasons why it is considered an excellent antivirus, it is because it is an alternative that does not bother the user at all, thanks to the fact that it runs in the background and does not interrupt its tasks and actions with messages or pop-up windows

Also, Windows Defender uses few system resources (such as RAM and CPU) and with this, it does not interfere with the other activities carried out on the computer.

Are free antivirus really 100% free or do they hide something?

One of the biggest doubts that Internet users have regarding antivirus programs is regarding their free use.

Since it is considered strange and suspicious to receive complete security assistance without paying absolutely and even more so, within the world of computing.

In this sense, it must be emphasized that, at the level of antivirus, there is no criterion that something can be delivered in exchange for nothing . So free antivirus is not really free.

In this way, the companies that develop antivirus solutions design their programs in order to admit their download and installation without the user spending money on it, which actually end up paying it in some way .

Well, although people are not fully aware, by accepting the terms and conditions of the antivirus, they are allowing the company to sell the data to companies that are dedicated to advertising , that is, the navigation and tracking data ( not personal information).

This means that, when acquiring a “free” antivirus , a kind of service provision contract is created in which, in order to obtain the protection of the antivirus, you will have to pay a price based on receiving advertising in the web , which is oriented under the criteria of your browsing data.

Thus, an affordable cost , given that they will not use your personal information at any time; unless it is a solution of dubious origin.

In which operating systems can we install malware protectors on our computers?

Believe it or not , it is not possible to install antivirus or malware protectors in all operating systems and given this clarification, most users will be wondering in what OS if they will be able to use these computer solutions to protect their computers and of course , safeguard your personal information.

Thus, we limit that all Windows, Linux, Mac and Android users have optimal alternatives to install on their computers, smartphones or tablets in order to avoid or eliminate any possible virus.

Either through free software or applications or paid. Taking into account that, on the contrary, the recognized Apple operating system, known as iOS, does not allow the installation of these tools on their computers and the reason for this, we will announce it to you, below.

Best Antivirus Table by platform or device
Antivirus for AndroidAntivirus for iPhoneAntivirus Applications
Antivirus for Windows 10Antivirus for Windows 8Antivirus for Windows 7
Antivirus for MacAntivirus for LinuxAntivirus for Laptop
Portable antivirusAntivirus for USB

Why is there no antivirus for Apple’s iOS operating systems?

Is there no antivirus for iOS?

Certainly, there is no antivirus for iPhone and iPad, since Apple does not accept antivirus applications in the App Store

This, because they ensure that the iOS platform designed by Apple has a very secure core, from which they affirm that this operating system is 100% infallible and for this reason, it does not require any antivirus.

In that sense, despite being classified as an extremely arrogant statement by the company, it is worth accepting that this Apple operating system is truly designed to be fully secure .

Mainly, thanks to the fact that its apps run in their own “sandboxes” or secure environments that isolate these applications and keep them away from the data of others, in order to prevent them from corrupting the files hosted on the OS.

Consequently, it is guaranteed that no iOS application will be able to compromise or usurp any user data , since it will not be able to leave its own “sandbox”

Being this, one of the most useful and best strategies in terms of security in the world of computing.

Taking into account that, apart from this, as another security measure, Apple restricts the installation of official apps from the App Store on iPhones and iPads and therefore, fully controls the code of the applications before making the approval to be able to enter your store.
