If the threat in question is a real virus and not a hoax, it is very likely that NOD32 detects it. ESET's active heuristic technology creates a virtual computer within the scanning engine which allows the scanner to observe what the program might do if allowed to run on a real computer. This can reveal potentially malicious activities that other detection techniques would not identify.
