ESET NOD32 Antivirus Overview
ESET NOD32 Antivirus is a commercial antivirus product for Windows from ESET, a long-established security vendor known for a light system footprint and a strong record in independent malware-detection tests. It provides real-time protection against viruses, worms, trojans, ransomware, and other malware, combining signature detection with heuristic and cloud-assisted analysis to catch new threats. It adds defenses such as exploit blocking, script and PowerShell protection, a UEFI scanner that checks firmware-level threats, and removable-media control, while aiming to stay unobtrusive and gentle on performance during everyday use and gaming. ESET NOD32 is a paid product with a free trial; its official site offers both a small live installer that downloads components during setup and a full offline installer for machines without a reliable connection.
