The Internet can be dangerous for your computer, but you don't have to worry with NOD32. The core of this software is ESET's ThreatSense® technology that gives your system protection against viruses, spyware, adware, phishing and more. It operates using AMON (Access MONitor) for scanning memory to detect malware in addition to Internet MONitor (IMON), Email MONitor (EMON), and Document MONitor (DMON). NOD32's interface has a minimalist design compared to other antivirus programs, but what it lacks in aesthetics it makes up for in speed. The installation file is under 10MB, and is set up to do automatic updates without interfering with your regular system operation.
