Abstract

The invention relates to a computer anti-virus protecting system and relative method, based on program behavior analysis, wherein said invention is characterized in that: it comprises a program judge part for recognizing the program of user computer and dividing the program into normal and abnormal ones; a program detecting part for detecting and recording the program behavior; a relevance analyzing part for building relevance tree to process relevance analysis, while said relevance tree comprises loading relevance tree and building relevance tree; a virus recognize information base comprising a program behavior information base and a impact recognize rule base; and a virus protective recognize part for comparing the picked behavior and the information of virus recognize information base, to judge if said program is virus. The invention can improve efficiency and avoid refresh delay of virus code.

Description

technical field [0001] The present invention relates to a computer protection system and method. Compared with the prior art, the virus feature code is not used for comparison, but the action behavior of the program is the feature, and it is a computer anti-virus protection based on the program behavior analysis. systems and methods. Background technique [0002] For a long time, the struggle against computer virus invasion and anti-invasion has been going on fiercely. With the use of computers more and more widely, the intensity of this struggle has also risen to a new height. After long-term struggle and practice, people have summed up many specific methods to prevent the invasion of computer viruses, and developed many corresponding prevention products. These products can be roughly divided into two categories. One is to isolate intruding viruses, such as firewalls, which prevent the entry of intruding viruses by restricting communication ports and protocols; the other i...
