Instructions virtual machine technology is one of the core technologies used in today's anti-virus field
the vast majority of anti-virus software scan engines use virtualization technology to analyze file and to revert the behavior of this program whether will be a threat to system security or not. According to this process behavioral characteristics
it is determined whether it is a virus or Trojan. Aiming at features of the virtual machine in anti-virus software
the difference between virtual environments and real environment were researched.Based on in-depth analysis of the virtual machine technology and the essential characteristics of a computer virus and Trojan
theory and practice of research were combined and the analysis of virtual machine instructions vulnerability in current anti-virus software was given.
