How does the antivirus program work?

 How does the antivirus work and what defense methods does it use against a virus? We have answered all these questions for you.

Since the history of the Internet, viruses have always been dangerous software for our computers.They are readily available to harm your computer and files in almost any environment on the Internet.Virus is a general term for malicious software (malware).For this reason, virus programs emerged. Viruses can be destroyed by this software.

We don't know what virus programs actually do, how they work, how they scan and protect our computer for viruses.In this article, we will try to answer the question of how the antivirus program works for you. If you are wondering how these interesting software works, if you want to learn the answer to the question of how antivirus works, you can read our article carefully.

How Do Antivirus Programs Work?

Viruses can access your computer and any point on your system and perform harmful operations there. Even the hard drive boot partition can contain malware, ie viruses.In general, viruses do not show themselves by taking the form of important system files on your computer.They continue to run in the background.Therefore, you do not realize that they are malicious software and you do not need to take precautions.

It would be the wisest way for you to use a robust antivirus program in the internet environment, which has all kinds of security risks against all these dangers.

In order for the antivirus program to scan your computer, it must first know what it is scanning.Every virus program has a library of viruses that it needs to scan.As these programs are developed, new viruses are added to their libraries.Therefore, it is very important for the security of your computer to update your virus program on time.

There are many antivirus programs, both paid and free.However, in general, almost all virus programs work within the same logic.When you give the "scan your computer" command to the antivirus program, it first examines all files and starts looking for suspicious codes.In other words, it accesses the program codes of the file it is scanning and compares them with the malware codes in its own library.If the program code of any of the scanned files matches the codes of a malicious software in the library of the virus program, the program determines this file as infected and sends you a warning message.

Almost all virus programs give you two different options for scanning.One is the quick scan and the other is the full scan option.Although these two options show some differences in software, they basically work in the same way.The quick scan option completes the scan much faster and the program generally performs a scan targeting the most frequently attacked files. 

However, besides being practical, it falls short of detecting viruses that have infected deep files.

The full scan option, as the name suggests, scans and examines all files on your computer one by one.Although this option takes much more time than a quick scan, it provides more comprehensive security as it scans all files on your computer.

What Actions Are Applied to Detected Malware?

When an antivirus program detects dangerous work and malicious software on your computer, it can generally take three actions.These processes are disinfection, quarantine and deletion, respectively.

1. Disinfection

If the antivirus program detects an infected file on your computer, it first tries to remove the software without any damage.In some cases, the detected virus is easily removed and the file is restored to the state it was before it was exposed to the malware.In such cases, the virus program performs the disinfection process and removes the virus and restores the file to its original state.

2. Quarantine

Computer viruses, like real-life viruses, are very susceptible to spread.They spread by interacting with other programs and files.They try to be more permanent by increasing their assets.In order to prevent such situations, the virus program quarantines the virus it detects.In other words, it moves the virus to a location that your computer cannot reach. In this way, the possibility of spreading the virus by cutting off communication with other files is eliminated.

3. Deletion

For some viruses to be removed from your system, the infected file must be completely deleted.These viruses are very effective viruses and do not leave any other options to the virus program.The result of malware removal is not what users want. 

However, this is the only way to get rid of such viruses. As a result, the virus program removes the threat by completely deleting the infected file as a last resort.

Antivirus programs generally provide protection to our computers in the internet environment.It provides online and offline protection options, allowing us to protect ourselves from malicious software on the internet. 

Therefore, using an antivirus program will be the right choice for all computer users.Since the antivirus program you use is constantly improving itself, it is very important to follow the updates and make the new updates on time. In this way.Your security software keeps your device safe from newly developed malware.

There is always a threat in every environment where there is internet.You can defend yourself against all these threats by having an antivirus program before it's too late.
