Anti-Virus Software is used to detect, prevent, and remove a virus or malware (Malicious-Software) from your computer.
A computer virus is a self-replicating program that typically has a detrimental effect, such as corrupting your computer or destroying data. It may slow your computer, display unwanted messages, or destroy important system files so that your computer will not be able to boot correctly.
It is highly recommended that you run Anti-Virus Software on your computer and keep it updated.
