Malicious file detection method and device, electronic equipment and storage medium

The invention provides a malicious file detection method and a related device. The malicious file detection method comprises the following steps: acquiring a function library file used by an input method program and a module file corresponding to the function library file in a memory; when it is determined that both the function library file and the module file are PE files, comparing a first code segment in the function library file with a second code segment in the module file, and determining machine codes, different from those in the first code segment, in the second code segment; when it is determined that the machine code contains the preset instruction, judging that the module file is a malicious file; the preset instruction comprises jmp, push, pop and int3; after a function library file and a module file are determined to be PE files, an abnormal machine code in the module file is extracted by comparing the two files, and then the malicious inline hook setting condition in the module file is determin
