The cause of the computer virus is the headache of all the people of the whole world. If asked where this virus is born? How come this virus? But in order to answer, you have to open the Internet. Let's take a look at it's history.

American scientist John Newman told the first computer virus in 1949. His hypothesis arises as a duplicate program for a program. After that it is known as a computer virus. Initially, there are many prominent universities in the laboratory to develop viruses and conduct experiments. During the time when the first virus that was created outside the laboratory spread on various computers, Elk Cloner was created and programmed at that time, USA Schoolteacher Richard Scenta.

These viruses spread through floppy disks. As a result, they did not have much effect on safety. The virus started spreading through the Internet in the early 1990's, but the biggest attack was in 1999. American citizen David L. Smith made it. The virus called 'Melissa' virus spreads through e-mail. In this process, a ward file is attached to e-mail, which would have affected the user's virus. Apart from this, Melissa virus spreads automatically to more than 50 people who have been infected by the infected person. As a result, users were forced to close the e-mail account due to Melissa virus.

Then came Worm's attack. Worm can be spread on all computers by itself, which is not possible for any other virus. In May 2000, Worm, a legend named Love-Bag, spread across the world. It contained a letter called "I Love You", which was used to open the Worm attack computer. The attack of Trojan Horse started in 2007. It's a kind of malware. Malware is a type of malicious software. These include viruses, worms, trojan horses, spyware, etc. The latest and recent time we are hearing about the name of the computer virus is 'Ransomware'.
