What is a Computer Virus?

As long as computers have been stable enough, people have managed to find ways to cause problems, and one of the most effective ways to create mischief on a computer is through malware such as a computer worm or virus.

Let us look at the topics covered in this blog:

Before going any further, look at this video in which our cybersecurity specialists explain the various cyber threats.


What is a Computer Virus?

We hear about it in the news almost weekly these days but what is a computer virus?

A virus is also software, a piece of code that has the ability to self-replicate. A virus can spread quickly from one computer to another and result in abnormal performance. A virus is a sort of malware; it attaches itself to the host file to get executed and spread all over the system.

A virus replicates itself by creating files and attaching itself to genuine software, allowing the user to run the virus. A virus can only spread with human interaction.

A computer virus is a program that disrupts the normal working of a computer without the user’s knowledge. A computer virus attaches itself to the files stored on the computer and damages them. When the replication succeeds, the affected areas are said to be infected with a computer virus.

A computer virus is a malicious piece of software or malware that, once it gets inside your computer, replicates and infects other computers in your network, stealing passwords, data, logging keystrokes, corrupting files, spamming your contacts, or even taking over your machine.


History of Computer Virus

Viruses were created for nefarious objectives. People generate viruses for a variety of purposes, ranging from harmless fun to malicious destruction.

The concept of an autonomously self-replicating entity dates back to the 1940s. Creeper was constructed and deployed onto the ARPANET in 1971; Creeper would bounce between computers, leaving only a message written on the teletype terminal, “I’m the creeper, catch me if you can.” Later versions of the program would drop a duplicate of itself on the visiting machine, making Creeper the first application to spread copies of itself autonomously on other systems. Thus, Creeper was the first computer virus created.

Another virus known as Elk Cloner would add itself to the system’s boot sector and be used to boot Apple devices, which would then add the cloner to every subsequent disc placed into the system by writing into the boot sector.
