Anti-virus

Anti-virus software is a foundational cybersecurity tool designed to protect digital systems from malicious software (malware). It continuously monitors computer systems using sophisticated scanning techniques — including signature-based detection, heuristic analysis, and behavioral monitoring — to identify, prevent, and remediate threats such as viruses, worms, Trojans, spyware, ransomware, and rootkits. By relying on regularly updated threat intelligence and definition files, anti-virus solutions can recognize both known and emerging attack vectors, intercepting threats in real time before they can execute and cause harm.

In the broader context of network and infrastructure security, deploying anti-virus software across all connected devices forms a primary line of defense against cyber threats. Its real-time protection features quarantine or eliminate suspicious files, preventing unauthorized access, data corruption, and system disruption. This makes anti-virus an indispensable tool for maintaining the integrity, confidentiality, and availability of information across an organization's digital landscape.
