NOD32 Antivirus System provides well balanced, state-of-the-art protection against threats endangering your PC and enterprise systems running various platforms from Microsoft Windows 95 / 98 / ME / NT / 2000 / 2003 / XP, through a number of UNIX/Linux, Novell, MS DOS operating systems to Microsoft Exchange Server, Lotus Domino and other mail servers.

One fundamental fact that makes the compilation of a unified list of viruses difficult is naming. When a new virus appears, the rush begins to identify and understand it as well as develop appropriate counter-measures to stop its propagation. Along the way, a name is attached to the virus. As the developers of anti-virus software compete partly based on how quickly they react to the new threat, they usually study and name the viruses independently. By the time the virus is identified, many names denote the same virus, and these different names have been used enough to stay around.

This release is for the following operating systems:
* Windows Vista 32-bit editions
* Windows XP Home Edition with SP1 / SP2
* Windows XP Professional Edition with SP1 / SP2

Eset Smart Security Anti-Spam:
The Antispam feature provides a defense against spam, as well as against email-borne threats that share many traits with normal spam. The antispam features of ESS utilize both client-based and server-based rules to provide immediate heuristic spam prevention, rather than relying only on signatures for detection.

All modes provide protocol filtering and intrusion detection.

A feature of ESET Smart Security's Personal firewall is the ability to mark specific programs as being network-aware. Using this feature, it is possible to identify and mark an application which can be used over a network (such as Microsoft Word) for far more rigorous heuristic checking of any network connections used by the application. This is more efficient than applying the same level of checking to every application, regardless of whether it has a network connection capability or not.
