What is Computer Virus and How to Eliminate It ?

What is Computer Virus and How to Eliminate It ?  कंप्यूटर वायरस क्या है और इसे कैसे हटाया जाए? - Do you know what computer viruses (computer viruses in Hindi) are? The use of computers comes to all people and people who use computers will hear the name of the virus. This name is a very familiar name in the internet world. Along with this it is a very scary name because it is very harmful for your computer and other electronic gadgets. This is why it enters the system when it can adopt it and destroy your data.
What is Computer Virus

Just like our health, viruses are not right and they spread many diseases in our body, similarly these viruses also bring many problems to the computer system. So this is the benefit of keeping information about all those computer users. Many people will know something about computer viruses that they are and what they do. But there are many people who have heard the name of the virus but they will not know what the virus can do in your computer. So today I'm going to tell you about the virus and how to eliminate it in this article. Hopefully you will find a lot to learn by reading these articles.


What is a computer virus?

Computer virus is a small software program designed to remove or damage your computer operation. Computer virus can break the system without our knowledge in such a way that it is not ours to fix it. The computer runs many software programs without any program program, computer programs can not work, software programs are designed to work properly and some programmable computers are also used to distort the work.

The computer was invented by humans, the computer was designed to run the computer and as I said that the virus is also a small program, it is also made by humans. Computer virus is not natural, it is not created by itself, it deliberately creates the programmer so that they can spoil other computers.


History of computer virus

Robert Thomas, who was the first engineer to work in BBN Technologies, first developed computer virus in 1971. This first virus was named "Creeper" virus, and it was an experimental program that Thomas had to do to infect ARPENET's mainframe himself. After transmitting the virus system, it displayed the following message on the screen: "I'm Cripper: catch me if you can."

The original wild computer virus was first tracked in the history of computer virus, which was "Elk Cloner". These Elk Cloner first infected Apple II operating system via floppy disk. This virus was developed in 1982 by Richard Skenta, a teenager at that time. Suppose that computer virus was designed according to mischief, but it seems that if a malicious program is installed in memory of a computer, then it can do a lot of work which will allow the user to run the system, and further There can be no control over their malicious programs.

The first person to name these malicious programs as "computer viruses" was Fred Cohen, who nominated it in 1983. The name came to light when he gave the title of these programs in these educational papers "Computer Virus - Theory and Experiments", where he wrote a complete description of how malicious programs work, what it is, and so on.


What can a computer virus do?

Computer viruses can corrupt or remove data in computer. You can complete the data stored in your hard disk computer viruses also go to other computers through e-mail attachments and make your computer vulnerable. Virus slows down your computer speed. And destroys the program.


What is malware

Malware full name is malicious software It is also a software program that harms the computer. Malicious software means bad software that is not perfect and once it comes to your system, it can completely degrade your system. Malware is also the name of a virus that slowly ends up in your system's data.

Where does malware come from our computer? Malware can come from many places in our system, and generally the most common sources of internet are used. We get some information every day on the Internet. If we have downloaded any pirated software, games and movies, we have gone to any malicious site to obtain that information and malware comes online from our computer. So online malware came to our computer, now we know how offline malware comes in our computer.

We all use Pendriv, CD, DVD in our computer. When we connect to our computer, we get connected to Pendrive and CD from other places to get the data, malware comes with all these things on our computer and our computer destroys the data.


Types of malware

There are three types of malware - viruses, worms and Trojan horses. These three are different; their work is also different. In these three different ways to make your computer defective. Let's tell us about all three what they do.


What is a virus?

Virus can corrupt files and software in your computer Suppose that your system has a word document in which the virus has arrived, it will either delete your document data or corrupt that document so that you do not get any information from it. . Or it may be that this virus completely corrupts your word processing software. This way, if you copy or share contaminated files, this virus also destroys your system by visiting another computer.


Types of Computer Viruses

Computer virus is a type of malware that has entered the memory of a computer and can also change program applications. Here computers are infected when these malicious codes are automatically duplicated. Here you will give people information about these computer virus types.

Boot Sector Virus - This type of virus infects the master boot record and is very difficult to get rid of them and often has to format the system to remove them. These are mainly spread by removable media.

Direct Action Virus - After installing them, they are also called non-resident viruses, computer remains hidden in memory. This is linked to those specific types of files that they infect. These users do not infect the experience and system performance.

Resident Virus - Direct Action Virus Resident Viruses are also installed in the computer. Apart from recognizing them, they are equally witty.

Multipartite virus - This type of virus can affect the system in many ways. Both these boot sector and executable files are simultaneously infected.

Polymorphic virus - Identification of these types of virus is a very interesting thing for traditional anti-virus programs because these viruses often change their signature patterns and whenever they repeat themselves.

Overwrite the virus - This type of virus deletes all the files that they infect. To remove these viruses from the system, the user must delete all infected files that cause data loss. Identifying these viruses is a very interesting thing because they spread through email.

Space Filler Virus - These are also called "cavity viruses". This name has been given because it fills all the spaces in the code, so files are not damaged.



File Infectious Virus:

Some file transit viruses come with program files such as .com or .exe files. Some file transit viruses also infect files with .sys, .ovl, .prg, and .mnu. Like when a particular program loads, the virus also loads. These viruses come with the user's computer.


Macro virus:

As the name suggests, these macro viruses mainly target some applications like macro language commands such as Microsoft Word.

These macro viruses have been designed in such a way that they easily add their macro code to the actual macro sequences.


Overwrite Virus:

This virus is designed so that it can overwrite itself and destroy any file or application data. Once it starts the attack, it appears to overwrite the code.


Polymorphic virus:

This type of virus is used by more cyber criminals. It's a type of malware type that can easily change its underlying code or otherwise and can change without any basic functions or features. It also does not come against this anti-malware. Whenever an anti-malware recognizes it, it modifies itself which makes it very difficult to catch.


Resident Virus:

This virus transmits itself into the memory of a computer; Actually there is no need for a basic virus program to infect any file or program. Even if you remove the original virus, one version of it is stored in memory which becomes active. This happens when the computer OS loads some applications or tasks. Since it is hidden in the system's RAM, it often does not detect antivirus or anti-malware.


Rootkit Virus:

This rootkit virus is a type of malware type that secretly installs an invalid rootkit in the infected system. It opens a door for the attackers, who give them complete control over the system, with the attacker can easily modify or disable any program or function. These rootkit viruses can easily bypass antivirus software, it is necessary to capture the rootkit scanner.


System or Boot-Record Infectious Virus:

These boot-record transiters execute executable code that are found in specific system areas of the disk. As the name implies, they are more infected in USB thumb drives and DOS boot sectors. There is not enough to see more of these boot viruses because the present system does not depend much on physical storage media.


What is worms?

Worms are similar to viruses but they multiply themselves and try to disperse more and more, which means that if your system has worms, then they start making multiple copies of different files which slow down the system Are there. If we copy the same file and share it with any other computer then the bugs will also go there and slow down the computer by making too many copies of the files.


What is Trojan Horse?

Trojan Horse is a very dangerous malware. These malware hide your identity in your computer. Let's assume that you are using the internet and if you have visited any site you will see an additional like "click here to win smartphones" and if you click on it, Trojan Horse malware can make your computer And you will not even report it and your system will be completely defective. They are also available as a lot of software on the internet. You think this is a real software but in reality it is a trojan hidden within that software and once it comes to your computer, it starts slowing down your computer. With this, a door will open so that your computer has more types of viruses and worms.


Virus infection signals in the system

How to know if your system is infected with a virus, so I'm going to talk about some warning signs below which is very important for all computer users -

• Slow system performance should be
• Screen pops up every time
• Play the program automatically
• Multiply / duplicate files
• Auto install new files and program computers
• Files, folders or programs are automatically deleted and corrupted
• Create hard drives different sound

If your system shows such warnings then you should know that your system may be infected with the virus. So soon download and scan a good bit of antivirus software.


How To Protect Your System With Viruses And Worms

Here you are going to give some suggestions to the people so that you can avoid these viruses.


what should we do

1. Always install a good antivirus in your system and keep it updated from time to time.
2. Do not open any email that you do not know about your sender.
3. Do not download anything from unauthorized websites like MP3, movies, software etc.
4. Get a good scan of all downloaded items as there is more chance of getting a virus.
5. After removing the disk only removable media such as Pendriv use
6. If you go to any website, then you are aware that this is a popular and registered website and do not click on any link which will later cause problems.


What do we need to do

1. Never open an email attachment if you are not aware of that sender.
2. Do not try to open any unwanted executable files, documents, spreadsheets without scanning.
3. Do not install documentation or executable software from unreliable websites.
4. Click on the ads that are motivated to entice you to click here and if you win the lottery, never click on such an add-on. Similar grids also come in e-mails, so do not open the mail at any time as it also has the possibility of malware.

I am sure that all of you know what is computer viruses ie computer viruses. It was a computer virus and some information related to it would help you avoid the effect of the virus.
