No virus or Trojan exists in the system and cannot be completely isolated from the process. Even if the hidden technology is used, it can still find clues from the process. Therefore, viewing active processes in the system is the most direct method for detecting viruses and Trojans. However, there are so many processes running simultaneously in the system, which are normal system processes and Trojan processes, what role does a system process that is
