Method, device and system for protecting safety of computer

Abstract

The invention discloses a method, a device and a system for protecting the safety of a computer. The method for protecting the safety of the computer comprises that: a first server receives the message digest 5 (MD5) value of the original information from a client side, wherein the original information is the start point information which is obtained through scanning a start point of the computer by the client side; the first server searches the start point state which corresponds to the MD5 value from a first database to obtain a first matching result, wherein the corresponding start point states of different MD5 values can be stored in the first database; and the first server sends the first matching result to the client side, so that the client side process the start point according to the operation command corresponding to the first matching result. The method is utilized to solve the problem that the method for protecting the safety of the computer in the prior art cannot protect the safety of the computer when the computer is started by virus by utilizing null files, and furthermore, an effect of protecting the safety of the computer is well realized.

Description

technical field [0001] The present invention relates to the technical field of computer network security, in particular to a computer security protection method, device and system. Background technique [0002] With the wide application of computer technology in various fields, threat programs have also caught up with the tide of the Internet era. These threat programs have evolved from purely malicious programs at the beginning to tampering with the default settings of the operating system and using safe computer programs as a trigger, so as to evade the detection and killing of security software and achieve the purpose of launching itself to execute malicious programs. The current security detection methods are all based on the detection of the file content dimension. The so-called detection method not based on the file content dimension refers to the security identification method that does not rely solely on the file content level. Provides various ways to load the prog...
