U 盘病毒的传播是借助 Windows 系统的什么功能实现的
自动播放功能。
相信大家对曾经非常流行现在势头也不弱的U盘autorun病毒都不陌生,U盘病毒的传播基本上都是借助于磁盘根目录下autorun.inf这一文件,计算机上的病毒首先将自身复制到已连接的U盘上,然后创建一个autorun.inf文件,当此U盘接入到其他计算机上以后,在你双击U盘时,系统就会根据U盘里autorun.inf文件中的设置去运行U盘的病毒或者指定的程序,导致系统出现各种非正常症状,如磁盘无法打开,系统卡机等。
Autorun.inf使得系统具有自动运行的功能,例如光盘的自动播放—一当插入光盘后,系统寻找光盘目录下面的autorun.inf文件,如果存在autorun.inf,系统便执行他里面的预设程序,开始播放影片。
给大家举个例子,例如U盘根目录下有123.ico,123.exe,123.txt和autorun.inf,其中autorun.inf内容为:
[AutoRun] Icon=123.ico Open=123.exe shel1\1=打开123.txt she11\1\command=notepad 123.txt
那么系统寻找到autorun.inf 以后,U盘图标就会显示为123.ico,双击便会执行123.exe,当右键U盘图标时菜单里多出一行”打开123.txt”选项,选中就会用系统自带的notepad(记事本)程序打开13.txt。
