The Business Edition packages add ESET Remote Administrator allowing for server deployment and management, mirroring of threat signature database updates and the ability to install on Microsoft Windows Server operating systems.

The acronym NOD stands for Nemocnica na Okraji Disku ("Hospital at the end of the disk"),[1] a pun related to the Czechoslovak medical drama series Nemocnice na kraji města (Hospital at the End of the City).

It was created in 1987 by Miroslav Trnka and Peter Paško at the time when computer viruses started to become increasingly prevalent on PCs running DOS.

Thus the original program was re-written and christened "NOD32" to emphasize both the radical shift from the previous version and its Win32 system compatibility.

Initially the program gained popularity with IT workers in Eastern European countries, as ESET was based in Slovakia.

Versions for Windows Mobile and Symbian OS were available as of September 2010, for both home and enterprise users.

[7][8] There were initially compatibility problems between ESET Smart Security 4.0 and Windows Vista Service Pack 2 but these were remedied by an update.

This version included Anti-Theft feature for tracking of lost, misplaced or stolen laptop.

[14] ESET SysInspector is a diagnostic tool which allows in-depth analysis of various aspects of the operating system, including running processes, registry content, startup items and network connections.

The program is offered free of charge, and can download updates if a network connection is present.

[16] On June 1, 2010, the first release candidate for ESET File Security for Microsoft Windows Server v4.3 was made available to the public.

This program is an updated version of ESET NOD32 Antivirus Business Edition designed for Microsoft Windows Server operating systems and contains a revised user interface, automatic exclusions for critical directories and files and unspecified optimizations for operation on servers.

[31] ESET Mobile Antivirus was aimed at protecting smartphones from viruses, spyware, adware, trojans, worms, rootkits, and other unwanted software.

It stood above competitors like Norton Internet Security and ZoneAlarm but below Windows Live OneCare and Avira AntiVir.
