sreng日志情况
启动项目   
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run]
    []
服务
[Net Login Helper / netlog][Stopped/Auto Start]   
测试中未发现 主程序 有创建启动项的行为 很奇怪
解决方法：
安全模式下(开机后不断 按F8键    然后出来一个高级菜单 选择第一项 安全模式 进入系统)
首先把系统时间改回来
把sreng改名为其他名称 运行
启动项目    注册表 删除如下项目
    []
“启动项目”-“服务”-“Win32服务应用程序”中点“隐藏经认证的微软项目”，
选中以下项目，点“删除服务”，再点“设置”，在弹出的框中点“否”：
Net Login Helper / netlog
把下面的 代码拷入记事本中然后另存为1.reg文件
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced\Folder\Hidden\SHOWALL]
"RegPath"="Software\\Microsoft\\Windows\\CurrentVersion\\Explorer\\Advanced"
"Text"="@shell32.dll,-30500"
"Type"="radio"
"CheckedValue"=dword:00000001
"ValueName"="Hidden"
"DefaultValue"=dword:00000002
"HKeyRoot"=dword:80000001
"HelpID"="shell.hlp#51105"
双击1.reg把这个注册表项导入

双击我的电脑，工具，文件夹选项，查看，单击选取"显示隐藏文件或文件夹" 并清除"隐藏受保护的操作系统文件（推荐）"前面的钩。在提示确定更改时，单击“是” 然后确定
然后删除C:\WINDOWS\1.exe
C:\WINDOWS\2.bat
C:\WINDOWS\2.exe
C:\WINDOWS\2.vbs
C:\WINDOWS\3.exe
C:\WINDOWS\IEXPLORE.EXE
C:\WINDOWS\tmp$$$.vbs

C:\WINDOWS\system32\spnup.dll
C:\WINDOWS\Debug\debug.exe
C:\WINDOWS\Web\css.css
C:\MSDOS.log
C:\WINDOWS\Temp\~tmp83.tmp
右键点击 菜单中的打开 打开D E删除gbk.com和autorun.inf
重启计算机 进入正常模式
下载 autoruns
http://www.skycn.com/soft/17567.html
由于这个软件也被映像劫持了 所以我们把他改个名字
打开这个软件后 找到Image hijack (映像劫持）
删除除了Your Image File Name Here without a pathSymbolic Debugger for Windows 2000 Microsoft
Corporation c:\windows\system32\ntsd.exe
以外的所有项目

然后修复你的杀毒软件 和其他安全软件 全盘杀毒即可
