Abstract

The invention discloses a method for preventing the infectious virus infection, which comprises the following steps: traversing all processes of a current system and processes newly created by a monitoring system; acquiring all process information in the systems, and filtering the processes during the operation; carrying out hook processing on functions in a security policy, and recording or duplicating relevant document information of the functions before invoking; monitoring the process after filtering, carrying out weighting processing on the information of the invoked function, and carrying out the weighting processing on document information related with the processes after finishing the processes; calculating the sum of the weight of the function information of the progresses and the document information, and outputting the judgment result of the progresses of infectious malicious codes corresponding to the sum according to the given numerical range in the security policy. The invention further discloses a device for preventing infectious virus infection. The method and the device can monitor the operation of the infectious malicious codes, judge the operation schedule of the malicious codes according to the monitoring of the operation state of the infectious malicious codes, and recover the infected document information.

Description

technical field [0001] The invention relates to the technical field of computer network security, in particular to a method and device for preventing infectious virus infection. Background technique [0002] With the development of the Internet, the threat of malicious code to computer users is becoming more and more serious. In recent years, the number of simple infectious malicious codes has gradually decreased, but this does not mean that the threat of infectious malicious codes is gradually decreasing. On the contrary, with the comprehensive enhancement of current malicious codes, the classification of malicious codes is becoming more and more blurred , a malicious code often has characteristics of multiple types of malicious code. Because infectious malicious code has a strong ability to spread and hide, it is still used by malicious code writers. [0003] The current prevention technology for infected malicious codes is mainly intercepted by hips (Host-based Intrusio...
