VIRUS CHECKER Meaning and
Definition
-
A "virus checker" refers to a software application designed to detect and eliminate potentially harmful computer viruses, malware, and other malicious software from a computer system. Also known as an antivirus program, it is an essential component of computer security that serves to prevent and mitigate the adverse effects of harmful programs.
Virus checkers are developed to scan a computer's files, documents, programs, and storage devices, actively identifying any suspicious or malicious patterns that could harm the system or compromise data. They operate based on a comprehensive library of virus signatures or behavioral algorithms, enabling them to recognize known viruses and detect abnormal behaviors.
The primary objective of a virus checker is to protect the computer from infection by dealing with any existing threats and preventing future attacks. It achieves this by removing or quarantining infected files and cleaning or repairing compromised elements of the operating system. Some advanced virus checkers also offer additional features such as real-time monitoring, email scanning, web protection, firewall integration, and automatic updates.
Using a virus checker is considered a fundamental practice for all computer users, as it helps ensure the security and integrity of digital assets. By regularly updating the virus checker and running scheduled scans, users can proactively guard against emerging threats, maintain system performance, and safeguard personal information from unauthorized access or theft.

The word "virus checker" combines two separate terms: "virus" and "checker".
- Virus: The term "virus" originates from Latin, where it means "poison" or "noxious substance". In the context of computers, it refers to a malicious software program designed to replicate itself and disrupt or damage computer systems or software.
- Checker: The term "checker" comes from the Old English word "cycere" which means an "overseer" or "controller". In the context of computer software, a "checker" typically refers to a program or tool that examines something for errors or issues.
