Define a computer virus:
DEFINE COMPUTER VIRUS
A computer virus, a type of malware, is exactly what it sounds like, a virus that affects computer software and hardware. A computer virus is a small piece of programming code that is created to “attack” the data files found around your network or on your computer. Viruses can often sit dormant within a machine for a very long time, waiting for a particular file to be booted. Some of the worst viruses in history caused billions of dollars in damage, and weakened security systems, exposing vulnerabilities and halting productivity.
Computer viruses, like biological viruses that infect human beings, require a host to survive. While a computer virus is running, it can affect other programs and documents, crippling the machine even further.
While some viruses are created to steal information from the host computer such as credit card numbers, passwords, or personal documents, others are set up to distress or frustrate the owner of the equipment. The simple act of creating a virus that becomes popular in mainstream media is reason enough for some programmers, such as the ILOVEYOU virus of 2000, which overrode existing files on the victim's machine simply to distress them. The ILOVEYOU virus held the Guinness World Record as the most ‘virulent’ virus of all time and cost nearly $15 billion in damages.
WHAT IS A COMPUTER VIRUS?
A computer virus, a type of malware, is a program that is intended to spread from one system to another via a contaminated program, file, or document. A computer virus is the digital equivalent of a really bad flu, spreading from one host to another, often undetected and often replicating or altering itself to cause major defects on your systems backend the operating system or hardware software GUI Interface.
While some computer viruses are immediately active, others remain dormant for some time, working slowly to cause destruction over time. A computer virus may be used as a way to frustrate the computer owner, simply for fun by the creator. However, others are created for malicious reasons such as stealing personal information or for financial gains.
Individuals who write viruses are always coming up with new ways to complete or trick their prospects into downloading the virus. And as our lives become more connected via our technology, it may be even easier to trick us into downloading it. Victims often fall prey to an email attachment, a social media post that requires a download or sign-in for access, or a music file that contains a virus.
Computer viruses work in phases during their lifecycle. Once a virus accesses its target’s computer, it may sit dormant while waiting to be triggered by the user. Triggering of the virus happens when the computer owner runs the program or file the virus is located within. Not all viruses have a dormant phase; some run immediately. As soon as the virus starts propagating or multiplying or replicating itself, it has moved to a new phase. The virus will copy itself and transfer to other programs or machines on the network. Each infected program will have a clone of the original virus which will then also go into a propagation phase.
The triggering phase of the virus’s life cycle is when the virus completes its intended function. This is often when the virus destroys your computer, steals your personal information, or begins spamming your contacts.
Infected machines often require software to remove the virus from the infected programs. Depending on the virus type, new hardware may also be needed to repair the damage, as some viruses will attack system critical files on the computer.
