病毒描述:

  该病毒运行后释放病毒自身到各个驱动器的根目录下,并释放一个autorun.inf文件,
当用户打开驱动器是就会自动执行该病毒,同时衍生大量的游戏木马到系统文件夹下;对
SPI进行劫持;下载大量游戏木马并且运行;对安全软件进行映像劫持

行为分析:

本地行为:

    %ProgramFiles%          系统程序默认安装目录
    %HomeDrive%           当前启动的系统的所在分区
    %Documents and Settings%    当前用户文档根目录
    %Temp%             \Documents and Settings
                    \当前用户\Local Settings\Temp
    %System32%           系统的 System32文件夹
    
    Windows2000/NT中默认的安装路径是C:\Winnt\System32
    windows95/98/me中默认的安装路径是C:\Windows\System
    windowsXP中默认的安装路径是C:\Windows\System32
