Antivirus Software – Definition & Detailed Explanation – Software glossary Terms

I. What is Antivirus Software?

Antivirus software is a type of program designed to detect, prevent, and remove malicious software, also known as malware, from a computer system. This includes viruses, worms, Trojans, spyware, adware, and other types of harmful software that can infect a computer and cause damage to files, steal personal information, or disrupt system operations. Antivirus software works by scanning files and programs on a computer for known patterns of malicious code and removing or quarantining any threats that are detected.

II. How Does Antivirus Software Work?

Antivirus software uses a variety of techniques to detect and remove malware from a computer system. One common method is signature-based detection, where the antivirus program compares files on the computer to a database of known malware signatures. If a match is found, the antivirus software can quarantine or delete the infected file.

Another method used by antivirus software is heuristic analysis, which involves analyzing the behavior of programs to identify potential threats. This allows the antivirus program to detect new and unknown malware that may not have a known signature.

Some antivirus software also includes real-time scanning, which continuously monitors files and programs as they are accessed or downloaded to detect and block malware in real-time. This can help prevent infections before they have a chance to spread throughout the system.

III. Why is Antivirus Software Important?

Antivirus software is important for protecting computers and data from the growing threat of malware. Malicious software can cause a range of problems, from slowing down system performance to stealing sensitive information such as passwords and financial data. Without antivirus protection, a computer is vulnerable to malware infections that can lead to data loss, identity theft, and other serious consequences.

Antivirus software helps to safeguard computers and data by detecting and removing malware before it can cause harm. It provides a layer of defense against cyber threats and helps to keep systems running smoothly and securely.
