Software programs are made to make the computer work properly and some programs are also made to spoil the work of the computer.

The human being invented the computer, his program was made by a human being to run the computer and as i said, the virus is also a small program, it has also been made by a human being. Computer virus is not natural, they are not made by themselves, programmers also make it consciously so that they can spoil other computers.

History of computer viruses?

Robert thomas, he was the first engineer who first developed a computer virus while working at bbn technologies in the year 1971.

Creeper message

This first virus was named "creeper" virus, and it was an experimental program that thomas himself had done to infect the mainframes of arpanet. After infecting the virus system, it displayed on the following message screen, "increased the creeper: catch me if you can."

The original wild computer virus that was first tracked was "elk cloner." this elk cloner had previously infected apple ii operating systems through floppy disks. This virus was developed by richard skrenta in 1982, which was a teenager at that time.

Suppose that computer viruses were designed according to prank, but it seems that if a malicious program is installed in the memory of the computer then it can do many such things by running the system to the user. You can also stop further and they will not have any control over these malicious programs. .

The first person to name these malicious programs as computer virus was fred cohen, who named it in the year 1983. This name came to the fore when he named these programs in an academic paper titled "computer viruses - theory and experiments" where he wrote full information about these malicious programs such as how it works, what is it can do etc.

How does a computer virus spread?

There can be many sources of virus infection in a computer or network that are sequentially understood. 

Internet:- when using the internet, there is the highest possibility of virus infection in your computer, because the internet is an open network in which thousands of viruses are inserted every day, which can cause maximum damage. 

Storage Device:- the second most common source of virus infection are storage devices, such as pen drives, hard disks, etc. Which are used by everyone in general today.  When we put a storage device on another infected computer to take or deliver data, then from there the virus often gets into our storage device and using the storage device on a working computer becomes active.

Download:- whenever you download something from the internet, such as a program, file or a movie, many times that file is already infected and the virus becomes active as soon as you play the file.

E-mail attachment:- all of us use the email service, many times infected attachments are sent in the name of big companies, which, if opened by mistake, the virus starts its work in an instant and the infected script or process is running.  It seems.

Pirated or cracked software:- whenever we try to install pirated software in our computer, the antivirus software deletes it by declaring it as a virus. The reason is that pirated software contains infected scripts and codes which harm your device.  Can deliver.

Infection with this happens when it encrypts the boot sector or the code becomes extremely damaged. The boot sector spreads through removable media.

It was very powerful in the 1990s when floppy disks were used. But it still spreads through the medium of usb drives and especially through email attachments.

Luckily due to the break in the bios modification, its usage has reduced in the last few years.

Virus Protection

There are some important rules to protect a computer, laptop, smart phone or other device from virus infection, which are necessary for a user to follow.  Key rules to protect the device from virus infection.  

License software has to be used because the license software is the foundation of any device in which we work, whether it is the os of the computer or some other program, if you use the license software, then there will be new updates in the software.

Those who are very important for the protection of the software and if the software remains safe, then the chances of getting infected are also reduced.  

Antivirus software is to be used. A good and licensed antivirus software is required to be installed and updated so that the computer can be protected.  

Use of storage devices carefully: we often use pen drives or external hard disks for data transfer, so before using them in every computer, to make sure that the computer is not infected, if the virus  if infected, your device will also get infected, which can harm your device and data.

Do not open an email attachment from an unknown source: if a mail or attachment from an email id arrives in your inbox that you have no connection with, or you find something strange, do not open it at all, because most of the big companies many times we get emails in the name of those who get infected and as soon as the user opens the attachment, she starts activating the computer and hurting them.  

Be alert while working on the internet: when you are searching on the internet, in which you are usually searching for something on google or working on a website, many times a pop up message comes in front of you like (if your computer is infected, put this software) or (your lottery is installed), then avoid clicking on this type of message.  And at the same time, always avoid opening porn, lottery and torrent websites; there is a high risk of virus infection from here.

How to remove the computer virus?

You have read how a device can be prevented from getting a virus infection and now we will know that if a computer has got a virus infection then how it can be cleaned or removed; first of all separate that computer from all other computers. 

That is, if connected to the network, remove it from the network and the internet and stop the transaction of data from it in any way, after that if it has antivirus installed, then update the antivirus and after the update the system will be full scanned. 

But if the license is not antivirus, then you can use malware byte or super anti spyware software, it is free for some time and is very effective, after full system scan, copy your valuable data from the drive and keep it in any drive so that if the system does not load after restart, then your data will be safe.

Then restart the computer and delete the temp files and cache files created in the system as soon as you restart,
