  • Method, apparatus and virtual machine for detecting malicious program
    Patent number: 10146938
    Abstract: A method, an apparatus and a virtual machine for detecting a malicious program(s) are disclosed. The method comprises: setting a virtual memory (301); reading a Master Boot Record (MBR) and storing the MBR in the virtual memory (302); and executing each instruction of the MBR in the virtual memory simulatedly, and detecting whether the virtual memory is modified after executing each instruction (303); if so, a malicious program is found, otherwise, continuing to execute the next instruction simulatedly until completing simulation execution of all instructions of the MBR. The technical solution can find the deformed malicious program(s).
