History

NOD32

The acronym NOD stands for Nemocnica na Okraji Disku ("Hospital at the end of the disk"), a pun related to the Czechoslovak medical drama series Nemocnice na kraji města (Hospital at the End of the City). The first version of NOD32 – called NOD-ICE – was a DOS-based program. 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. Due to the limitations of the OS (lack of multitasking among others) it didn't feature any on-demand/on-access protection nor most of the other features of the current versions. Besides the virus scanning and cleaning functionality it only featured heuristic analysis. With the increasing popularity of the Windows environment, advent of 32-bit CPUs, a shift in the PC market and increasing popularity of the Internet came the need for a completely different antivirus approach as well. 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. Though the program's abbreviation was originally pronounced as individual letters, the worldwide use of the program led to the more common single-word pronunciation, sounding like the English word nod. Additionally, the "32" portion of the name was added with the release of a 32-bit version in the Windows 9x era. The company reached its 10000th update to virus definitions on June 25, 2014.

SysInspector Logs are standard XML files and can be submitted to IT experts for further analysis. Two logs can be compared to find a set of items not common to both logs. A log file can be saved as a service script for removing malicious objects from a computer.
