Embodiment Construction

[0030] Such as figure 1 As shown, in an ordinary computer system, a system 1, a target program 2, a computer operating system 3, a network connection module 4, a file system 5, and a registry for detecting and defending computer malicious programs that can be executed by the computer are installed Database 6; also have common CPU, internal storage device and external storage device (not shown in the figure) in this computer. The target program 2 may exist in files in internal and external storage devices of the computer, as well as files or data packages downloaded and transmitted from the network. The target program 2 can run in the computer operating system 3, and can call related functions to operate the network connection module, file system, registry database and other software and hardware. The system 1 for detecting and defending against malicious computer programs can effectively monitor the process of calling related functions by the target program.

Description

technical field [0001] The invention relates to a technology for detecting and defending computer viruses, Trojan horse programs and other malicious damage programs, especially a system and method capable of detecting and defending unknown malicious programs. Background technique [0002] For a long time, computer programs (hereinafter collectively referred to as malicious programs) have destructive execution results (destroy the system, tamper with files, affect system stability and execution efficiency, steal information, etc.), mainly computer viruses, logic bombs, Trojan horse programs, and spy programs. ) have always been a major problem in the use of computers, and they pose a major threat to information security. There are many types of these malicious programs, and they spread in various ways, making it hard to detect. For example, many malicious programs use the loopholes of the operating system to spread through the network or through the executable files in the in...
