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. The first version of NOD32 - called NOD-ICE - was a DOS-based program. 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).
