An antivirus is a software program that is designed to detect, prevent, and remove malicious software or malware from a computer system. It works by scanning files, programs, and the system memory for any known patterns of malicious code, such as viruses, worms, and Trojans. When a virus or other malware is detected, the antivirus takes action to either remove or quarantine the infected files to prevent further spread of the infection.
Here are some of the features of an antivirus software:
Real-time scanning: An antivirus software continuously monitors the system for any potential threats in real-time, and alerts the user if any suspicious activity is detected.
Malware detection: Antivirus software is designed to detect various types of malware, including viruses, worms, Trojans, and spyware.
Automatic updates: Antivirus software providers regularly release updates to their virus definition databases to stay up-to-date with the latest threats. Automatic updates ensure that the software is always current and can detect the latest threats.
Quarantine and removal: When a threat is detected, the antivirus software takes action to either remove the infected files or quarantine them to prevent further spread of the infection.
Firewall protection: Some antivirus software includes a firewall feature that provides an additional layer of protection against hackers and other unauthorized access to the system.
Email and web protection: Many antivirus software programs also offer email and web protection, which helps to prevent phishing scams, spam, and other online threats.
Overall, an antivirus is an important tool for protecting your computer and personal data from various malware and cyber threats. I
