Malicious program defense method and device, electronic equipment and storage medium

The embodiment of the invention relates to the technical field of computer security, in particular to a malicious program defense method and device, electronic equipment and a storage medium. The malicious program defense method comprises the following steps: dynamically analyzing a known malicious program to obtain a malicious vector for judging that a computer system is damaged; changing malicious codes in the malicious file into non-malicious codes to obtain a non-malicious file; and inputting all the obtained non-malicious files into a target position in the to-be-defended computer system so as to perform malicious program defense on the to-be-defended computer system. According to the arrangement, after the malicious program enters the computer system and calls the non-malicious file located at the target position, the malicious program cannot infect the computer system after calling the non-malicious file due to the fact that the code in the non-malicious file is the non-malicious code, and therefore ef
