如何從文件中讀取並匹配簽名以確定它是否是病毒

Question

我得到某種文件數據，但它只是隨機文本。 我希望能夠讀取並匹配文件的病毒簽名：

import glob, re

def SignatureCheck():
    print("CHECK FOR VIRUS SIGNATURES")

    programs = glob.glob('C://Users//user//desktop//Screenshot (156).png')
    for p in programs:
        FileInfected = False
        file = open(p,"r", errors="ignore")
        lines = file.readlines()
        file.close()

        for line in lines:
            print(line)
            if (re.search("virus-signature",line)):
                FileInfected = True
        if (FileInfected == False):
            print(p + " has no virus")

    print("scan complete.")

SignatureCheck()
