Features and Services

Smarter Scanner - Threats don't always enter your network in ways you expect. ESET NOD32 Antivirus inspects SSL-encrypted communication channels like HTTPS and POP3S and intelligently scans compressed files to find hidden threats other products miss. Proactive protection begins at the earliest point in system startup to ensure your computer is always secure.

Clean and Safe Email - Email scanning for Microsoft Outlook, Outlook Express, Mozilla Thunderbird, Windows Live Mail, Windows Mail, and other POP3/IMAP mail clients, ensuring your email is free of viruses and other threats.

Removable Media Security - Threats can enter your PC from removable media such as USB thumb drives. For self-running media, ESET NOD32 Antivirus scans autorun.inf and associated files when the medium is inserted, in addition to scanning any file on any removable device when it is accessed, or during a full-scan of the media. Power users can adjust ESET NOD32 Antivirus to perform additional levels of scanning on removable media.

System Tools - ESET SysInspector and ESET SysRescue simplify diagnosing and cleaning of infected systems by allowing deep scans of system processes to find hidden threats, and creating bootable rescue CD/DVD or USB drives to help you repair an infected computer.

Self Defense - ESET NOD32 Antivirus has built-in technology to prevent malicious software from corrupting or disabling it, so you can rest assured your system is always protected.

ESET Remote Administrator - Simplify all aspects of running antivirus on your business network with ESET's comprehensive management tool. New version 4 features lower the cost of ownership, improve security posture, and reduce response time to incidents. From a single console, manage Windows, Mac, Linux and mobile device endpoints with minimal system resources. Empower your IT team to work smarter, not harder. View datasheet

Protection from the Unknown - Award-winning ThreatSense® technology uses multiple layers of threat detection to deliver the most effective protection possible against new attacks. And ThreatSense is smart; it raises far fewer annoying "false alarms" than other products that use heuristics.

Built for Speed - ESET NOD32 Antivirus is lightning fast and unobtrusive. Even disk-intensive operations like performing a "full disk scan" run smoothly in the background without affecting end user productivity.

Easy on Your System - ESET NOD32 Antivirus is "lean and mean," typically using just 44 MB of memory, a fraction of what other products consume. Because it's fast and "light," upgrading your existing antivirus protection to ESET NOD32 Antivirus can extend the useful life of your PCs.

Easy to Manage - Managing antivirus for hundreds or more endpoints doesn't have to be time consuming and cumbersome. ESET Remote Administrator is comprehensive and easy to use. Create policies for groups and schedule tasks to automate routine activities from intuitive screens.

ESET NOD32 Antivirus

ESET ThreatSense® Technology

Finds malware that other antivirus products miss and stops emerging malware as they are released instead of hours or days later. It is swift and has the lowest false positive rate in the industry.

Usability Improvements - For administrators, version 4 offers:

  • License Manager with simplified tools to manage multiple licenses with different terms
  • Read-only access for Management Console which enables multiple administrators to share tasks without risk of overwriting configurations
  • Notification Manager to keep administrators informed of all key events with customizable alerts
  • More efficient use of network bandwidth and improved log storage scalability
  • Advanced Protection status screen that informs you of threat detections
  • Password protection that prevents ESET NOD32 Antivirus from being uninstalled by unauthorized employees or visitors
