The virus detection method that creates a virtual environment that simulates the central processing unit (CPU) and memory of the computer is called code emulation.
This method involves creating a virtual environment where the suspicious program is executed to observe its behavior without affecting the real system. This helps to detect any malicious activities and identify the type of threat posed by the program. Code emulation is an effective virus detection method as it allows for the analysis of malware that may be difficult to detect through other means, such as polymorphic or encrypted viruses. Overall, code emulation is an important tool in the fight against malware and is widely used by antivirus software to protect computer systems.
