Antivirus or Types of antivirus software simply, sometimes known as antimalware software, is computer software used to prevent, detect and eliminate malicious software. There are many types of antivirus that we will explain in this article and its function.
What is an antivirus?
Antivirus software is a program or setup of programs designed to prevent, search, detect and eliminate software viruses and other malicious programs such as worms, Trojans, adware and more.
These tools are essential for users to have them installed and updated, since a computer without the antivirus software installed will be infected minutes after connecting to the Internet.
The bombing is constant and antivirus companies constantly update their detection tools to deal with more than 60,000 new pieces of malware created daily.The antivirus software was originally developed to detect and eliminate computer viruses, hence the name.
However, with the proliferation of other types of malware, antivirus software began to provide protection against other computer threats. ransomware, keyloggers, backdoors, rootkits, Trojans, worms, malicious LSPs, dialers, fraudtools, adware and spyware.
such as infected and malicious URLs, spam, phishing scams and attacks, online identity (privacy), online banking attacks, (SET)social engineering techniques, advanced persistent threat (APT) attacks and DDoS botnet.
There are several different companies that create and offer different types of antivirus software and what each one offers may vary, but they all perform some basic functions:
Scan specific files or directories for malware or known malicious patterns Allows you to schedule scans to run automatically It allows you to start scanning a specific file or your computer, or a CD or flash drive at any time.

It is essential to have antivirus software installed on your computer to help protect your computer system. This protection will protect your system against potential damage, and will protect your personal information so that it does not spread over the Internet.
Antivirus software identifies, prevents and removes malware from a computer system or your pc. Malware is any amount of viruses and software bits that claim to damage the computer or steal information, such as viruses, adware, rootkits, backdoors, hijackers, keyloggers, spyware, Trojans and worms. Modern antivirus software uses several methods to detect and remove malware.
Different types of antivirus software:
Basically, antivirus programs fall into three categories, depending on the function they were designed for, let’s see what these types of antivirus are:
In the first place is the so-called “Preventive Antivirus”, those who fulfill the function, as the name implies, of anticipating the infection by intercepting and analyzing all data entry and exit operations.
It should be noted that this type of antivirus to perform its task must be installed on the disk and reside in the memory of the PC, so there are many resources that slow down the computer. It is characterized by anticipating infection to prevent the entry of a malicious program into the computer.
Therefore, its name refers to its ability to prevent virus attack on computer systems. However, by bordering on computer memory, there is no other user, which can slow down the operation of the computer.
Another type of antivirus is called “Identification Antivirus”, whose main function is to identify threats that are already active on our computer and that affect system performance.
To achieve its purpose, this type of antivirus scans all files on the computer in search of malware-related byte strings. Its function is, as the name implies, to identify the threats that affect the performance of the operating system.
To do this, scan the system and examine the byte sequences of the codes that are related to the dangerous programs.
The last type of antivirus are the so-called “Antivirus Decontaminants”, which aims to eliminate an infection when it has already occurred and has attacked the computer. Many of these antivirus also try to return to the previous state at the time of infection.
Its objective is to focus on the elimination of the infection that has damaged the computer, to eliminate viruses. In addition, it is also about to return to the system the state in which it was found before being attacked by the malicious program.
Spyware known as spyware, others as appropriation of data for fraudulent purposes on websites, some as pop-ups, entry into our email address of messages that have not been requested.
These are some of the threats to which they are exposed in their owner. To avoid each of them, there are tools that are part of the antivirus, especially in its full versions, let’s see what are these types of antivirus:
The firewall software analyzes the incoming and outgoing data packets in a network; that is, all the information sent and received through the computer’s network connection.
To accomplish its task, the firewall software analyzes each piece of information sent and compares it with a set of predefined rules.
These rules allow the firewall to determine whether the information packet should be allowed through the firewall on the computer, or blocked to avoid possible damage or infection.
Over time, firewalls have become more advanced in their ability to filter network traffic. Currently, there are three varieties of firewalls for consumer use: network or packet layer filters, proxy servers and application layer firewalls.
An anti-spyware is a type of software that is designed to detect and eliminate unwanted spyware. Spyware is a types of malware that is installed on a computer without the user’s knowledge to collect information about them.
This may pose a risk to user security, but more often spyware degrades computer system execution by taking over processing power, installing additional software or redirecting user browser activity.
Anti-spyware can also be called apyware on the Internet. Because “a” and “s” are next to each other on the keyboard, many people by chance type “apyware” when they try to search for “spyware.” Manufacturers and other stakeholders capitalize on this by announcing “apyware.”
Antipop-ups (pop-up blocking):
Its objective is to identify and avoid the execution of annoying windows that open when browsing the Internet, known as pop-up windows. Many of these windows hide many spyware.
Antispam refers to services and solutions that focus on blocking and extinguishing the effects of illegal emails (or spam) on email users. To achieve this goal, different types of antispam systems have been integrated with the email systems of many Internet and email service providers (ISPs).
An antimalware is a types of software program designed to prevent, detect and eliminate malicious software (malware) on IT systems, as well as individual computer devices.

In conclusion, antivirus and security software has become an essential part of modern computer use. Firewalls inspect the data that flows between the computer and the Internet and try to filter the information packets that seek to exploit vulnerabilities.
Antivirus software has become quite sophisticated, often with signature-based detection methods, heuristic detection methods, rootkit detection and real-time scanning to prevent computers from becoming infected with malware.
