Embodiment Construction
[0023] The malicious software detection flow chart of the embodiment of the present invention is as follows figure 1 shown. The flowchart is mainly divided into three modules: feature extraction module, AROW (an online classification algorithm) classifier module, and comprehensive evaluation module.
[0024] The feature extraction module extracts the system authority features, program control flow chart features and system call features of the application program, calculates the frequency vectors of each feature (respectively the first frequency vector, the second frequency vector, and the third frequency vector), and combines them into The eigenvectors are integrated, and then the AROW algorithm is used to classify, and the classification result is weighted with the first contribution value of the power record to the malware detection and the second contribution value of the intent record to the malware detection to judge the application program.
[0025] In the feature extr...
