Multi-task malicious software detection method and device, electronic equipment and storage medium

The embodiment of the invention provides a multi-task malicious software detection method and device, electronic equipment and a storage medium. The method comprises the following steps: acquiring a target malicious code file from target malicious software; vectorizing the target malicious code file to obtain a one-dimensional vector; performing general feature extraction on the one-dimensional vector through a sharing layer to obtain general features; respectively inputting the general characteristics into a first task specific layer and a second task specific layer to obtain the output of the first task specific layer and the output of the second task specific layer; the output of the first task specific layer is converted into first task output through a first output layer, and the output of the second task specific layer is converted into second task output through a second output layer; and obtaining a target malicious software detection result based on the first task output and the second task output.
