virustõrjevahend

Virustõrjevahend, also known as antivirus software, is a type of computer program designed to detect, prevent, and remove malicious software, including viruses, worms, Trojan horses, and other malware. These programs use various methods to identify and neutralize threats, such as signature-based detection, heuristic analysis, and behavioral monitoring.

Signature-based detection involves comparing files and programs against a database of known malware signatures. Heuristic analysis examines the behavior of files and programs to identify suspicious activities that may indicate the presence of malware. Behavioral monitoring observes the actions of software in real-time to detect and block malicious behavior.

Antivirus software can be categorized into different types based on their functionality. Real-time protection monitors the system continuously to detect and block threats as they occur. On-demand scanning allows users to manually scan specific files or the entire system for malware. Email scanning filters incoming and outgoing emails to detect and remove malicious attachments and links.

Antivirus software is an essential component of cybersecurity, helping to protect users from the ever-evolving landscape of malware threats. Regular updates to the software and its malware databases are crucial to ensure continued protection against new and emerging threats. Additionally, users should practice good cybersecurity habits, such as keeping their operating system and applications up-to-date, using strong passwords, and being cautious when downloading files or clicking on links from unknown sources.
