  技术分析
  ==========


  MSN蠕虫变种,向MSN联系人发送欺骗文字消息和带毒压缩包,当联系人接受并打开带毒压缩包中的病毒文件时系统受到感染。

  病毒运行后复制自身到系统目录:
  %windir%\system\ehSched.exe

  生成包含自身的ZIP压缩包:
  %windir%\system\IMG024.JPG.zip
  其中包含的病毒文件名是IMG024.JPG.com。

  创建启动项:
 
  [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
"ehSched"="%Windows%\system\ehSched.exe"

  根据染毒系统语言向MSN联系人发送以下文字和带毒压缩包IMG024.JPG.zip:
