The embodiment of the invention provides a computer-virus detecting method and device. The computer-virus detecting method comprises the following steps of: recording password error events, wherein the password error event comprises a client-side identifier, a process identifier and a time identifier; counting the times of the password error events of in the same process of the same client side in preset time; judging whether the times of the password error events in the same process of the client side in the preset time in exceed the preset threshold time; and if the times of the password error events in the same process of the client side in the preset time is over the preset threshold, determining that the process is a computer-virus source. The method has the advantages that the accuracy rate of computer-virus detection adopting the password as an attack means can be obviously increased, simultaneously the detection method is low in computation complexity, only adopts the time and the process as dimensionality, and is simple in detection standard and easy in maintenance and optimization.
Description
Technical field [0001] The present invention relates to the computer field, in particular to a computer virus detection method and device. Background technique [0002] Computer virus (Computer Virus) is a set of computer instructions or program codes inserted in a computer program by the compiler to destroy computer functions or destroy data, affect the use of the computer and be able to replicate itself. Different from "viruses" in medicine, computer viruses are not naturally occurring, but are a set of instruction sets or program codes compiled by some people using the inherent vulnerabilities of computer software and hardware. It can be lurking in the storage medium (or program) of the computer through a certain way, and it will be activated when certain conditions are met. By modifying other programs, it can put its own exact copy or possibly evolved form into other programs. Thereby infecting other programs and destroying computer resources. [0003] At present, there is a ...
