A malicious-process-determining method, a data processing apparatus, and a recording medium according to the present invention each consists of reading the data stored in a buffer memory by one byte, and for a plurality of instruction sequences each having a different read address, sequentially analyzing what kind of instruction code is contained therein. When the int instruction is contained in the analyzed instruction sequence, the number of times the immediate value is pushed to the stack is greater than 1, and the character code corresponding to “/” is contained in the virtual stack, a determination is made that a malicious code is contained in the relevant instruction sequence.
