Because the various functions which these programs can use in their fight to identify and suppress any cyber threat, They are also classified according to their purpose:

detectorsThey are responsible for notifying users of the presence of a known virus. However, only the user can solve the problem to eliminate the infection.
Eliminators-repairersTheir goal is to eliminate threats from the affected parts of the system and, in addition, they manage to repair the computer to return it to normal.
HeuristicsThey are a kind of simulator, because they simulate the execution of programs in order to see how they behave and, based on that, identify suspicious situations.
ImmunizersThey have the ability to anticipate the entry or attack of any malicious program. In this way, they monitor the execution of applications, copy files, and format disks.
ResidentsIts main function is to analyze software from the first moment the user accesses it, and thereby examine whether the file contains viruses or not.

According to its specific objective

This classification is based on the specific tools that are part of each antivirus solution, especially in their full versions for prevent specific threats.

The following are the types that exist:

AntimalwareThis program has the necessary functions to block and remove any form of malware. Keep in mind that malware consists of malicious programs that infiltrate computers to quickly damage them.

Antivirus identifiersAs their name suggests, these tools are responsible for identifying threats that could negatively impact operating system performance. Therefore, their function is to scan the system and examine the byte sequences of code associated with malicious software.
Antivirus preventersTheir distinguishing feature is their ability to anticipate infection and prevent malicious programs from accessing the computer. However, because they are stored in the computer's memory, they can slow down its performance and are therefore not widely used.
Antivirus disinfectantsThey are focused on ending the infection that has caused the damage to the computer and therefore, they are responsible for eliminating existing viruses to return the system to its natural state.

In this regard, it is important to emphasize that, In the field of antivirus software, there is no principle that something can be given away for nothing.Therefore, free antivirus programs are not truly free.

In this way, companies that develop antivirus solutions design their programs to allow download and installation without the user spending any money on it, which They actually end up paying for it somehow.

Well, even if people aren't fully aware of it, when they accept the antivirus terms and conditions, they are allowing the company to selling the data to companies that specialize in advertisingThat is, browsing and tracking data (not personal information).

In this way, we specify that all users of Windows, Linux, Mac and Android They have excellent alternatives to install on your computers, smartphones or tablets in order to avoid or eliminate any possible viruses.

Whether through free or paid software or applications. Taking into account that, on the contrary, Apple's renowned operating system, known as iOS, does not allow the installation of these tools on its devices. And the reason for this, we will tell you below.

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

Certainly, there is no antivirus for iPhones and iPads, given that Apple does not accept antivirus apps on the App StoreThis is because they claim that the iOS platform designed by Apple has a very secure core, which makes this operating system 100% infallible and therefore does not require any antivirus software.

In that sense, despite being categorized as an extremely arrogant claim by the company, it is worth accepting that Apple's operating system truly is. It has been designed to be completely safe.

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

Therefore, it is guaranteed that No iOS application will be able to compromise or steal any user data, given that he will not be able to leave his own “sandbox”This is one of the most useful and best strategies in terms of security in the world of computing.

Taking into account that, apart from that, as another security measure Apple restricts the installation of official App Store apps on iPhones and iPads Therefore, it fully controls the code of applications before approving them for inclusion in its store.
