Computer virus has become a serious threat in the digital world. Because of this, any computer user needs to know what is a virus. How does the virus get access to any device to damage that device? And how can we avoid this computer virus?
What is a computer virus and how can it be safe?
Speaking of the definition of computer virus, “Virus” is a type of electronic code. The code that is used to get the corrupt information present in the computer.
VIRUS flower form is Vital Information Resources Code. This is a subtle computer program. Those who enter any computer, interfere with the functioning of that device. This is an Auto-Exchange program.
Generally, computer viruses slow down hard disk speed by reaching the hard disk’s boot sector. This may cause computer programs to shut down or work-pages may be jammed.
A computer virus gradually damages the device by spreading the device’s memory. Because of which once the virus spreads it becomes difficult to recover the lost data.
Now the question is how do computer viruses work?
If you understand with the help of an example, you have to type the letters in the computer with the help of keyboard to create documents through the application of MS Word, Spreadsheet Program, Presentation Program etc. And they have to print prints to print. That means this application works on the commands given by us to the computer.
But there is a clock on the other side, whose work time is to be displayed. But we do not need any command or program to run it. And it works 24 hours in our computer. Because of which we do not need to set the time again and again.
Programming in Computer Clock is done in such a way that these programs do their work without having to install or open. Such programs can be called by Default Programs. In the same way, like in the Basic program, there are such types of viruses in the virus that can be shut down our computer, delete the files, and lock the computer, slip the data speed of the computer, files automatically Transfer from place to place, etc. Other commands are programmed within the computer virus. Thereby causing a lot of damage to the computer.
Who makes a computer virus?
Simply put, these are the people who are privileged to computer programming. That is, they are experts in computer programming but in this world connected with technology, crime, spreading fear, or causing harm to others, this computer creates a virus. These people can also be called hackers.
How do computer viruses reach our computers and devices?
Today the whole world is connected to the world because of the Internet. The Internet is also a network. And the computer reaches the virus in the computer.
When a user browses the Internet in a computer. Virus clicks on an unknown website or link, then the virus reaches the device too. Apart from this, in the offline way, computer virus can spread from one computer to another with the help of CD’s, floppy disks and pen-drive etc.
Although the use of floppy disks or floppy drives is reduced in the present time. But pen drive is used for many tasks like Windows Installation, File Transfer, Storage Devices etc. Using the Pen Drive, the virus can easily access one device from one device to other.
If for some reason the virus enters a Pen Drive and in the future if we transfer that pen drive to any computer device, mobile (via OTG Cable), then transfer the file to other viruses. Increases.
Downloading software through the Internet, downloading programs, watching porn movies on porn site, visiting unknown links, email attachments, engaging viruses, viruses can be installed by entering our device. And like in the termites, inside the device memory can store store data in the inside.
