The method includes: obtaining text strings contained in each virus sample within a virus sample set; selecting text strings for use as virus signatures candidate according to a first frequency at which each text string occurs in a non-virus sample set and a second frequency at which each text string occurs in the virus sample set; calculating an information entropy of the virus signatures candidate according to a quantity of virus samples containing the virus signatures candidate and a quantity of non-virus samples containing the virus signatures candidate; and selecting virus signatures from the virus signatures candidate according to the information entropy. The present disclosure may timely identify the latest virus signatures and ensure that the obtained virus signatures are optimal signatures and may identify a wide range of virus variants."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and device for obtaining virus signatures","description":"A method and a device for obtaining virus signatures in the field of computer security have been disclosed.
