What Is Antivirus And Its Types

People using mobile devices and computers often know what an antivirus is and what harm it can cause.

What Is Antivirus: Viruses are a type of program that enters any system and destroys the data present in it. They steal the data present in our system, which we do not want at all. To avoid all this, a program is used, which we call antivirus. Now you might be thinking that viruses are understandable, but what is this antivirus, and how does it eliminate the viruses present in the system?

Just as the human body needs a good daily routine, i.e., good food, yoga, and exercise, to function and stay healthy so that no disease or virus can enter the body, so too does the data present in the computer system. Antivirus is very important to keep it safe.

What Is Antivirus?

Just as viruses enter the system due to our carelessness, other sources, pen drives, etc., they damage the data present in our computer and slow down the speed of the system.

Antivirus is a type of program code that identifies viruses and deletes them so that the data present in the computer, like photos, files, and videos, can remain safe.

It is also known as anti-malware because it protects the computer from malware and spyware and gives protection to the system. The first antivirus program, Virus Scan, was created in 1987 by Andreas Lüning and Kai Fage.

This antivirus was launched by the McAfee company. But as new technology progressed, security companies started creating new software programs, which are quite popular today. We have explained in detail below how many types of antivirus are there and which is the best antivirus.

How Does Antivirus Work?

When we install antivirus on our computer, it scans all the files present in it. While scanning, each file is scanned differently so that the difference between the file and the virus present in the computer can be detected, and in this way, it identifies the virus in the data file present in the computer and destroys it.

As we told you above, a virus is identified in a system by scanning it in different ways. How it does so is as follows:

• Heuristic-Based Detection
• Sandbox Detection
• Signature-Based Detection
• Data Mining Techniques
• Behavioural-Based Detection

Features Of Antivirus

Full System Scanning

It is best to use this feature whenever there is a new update for the antivirus. When a new update comes, it can identify new viruses, so when we scan and apply this update to the entire system, we will know if there are any viruses.

Virus Definition As Update

This is the most important feature whenever a new update comes, it is brought in the form of an update that defines the virus and tells the antivirus program which files can be viruses.

When a new virus is created and runs on the Internet, a new virus is created for it and sent as an update to your antivirus. Which is capable of recognizing the virus, otherwise, if our antivirus program has an old definition and some new virus has entered the system, then it does not recognize it.

Background Scanning

We always work in our system, and while working, if any software starts doing its work and it causes difficulty in working in the army, then it is a loss for us.

If an antivirus program runs in the background while working, then, in a way, the system is not only safe, but we also do not face any problems while working.
