中了QQ尾巴
然后任务管理器也被锁了，注册表也不能修改了
瑞星杀毒软件一打开就自动关闭了，别的杀毒软件打开也自动关闭
我买的可是正版2005的，198元人民币啊

建议用光盘在DOS下杀毒试试

C:\WINNT\SVOHOST.exe 这个文件可疑,不是系统的文件,找到它进行删除,最好在安全模式下操作,正常的应该是这样C:\WINNT\system32\svchost.exe  注册表中也有O4 - HKCU\..\Run: [ctfnom.exe] C:\WINNT\SVOHOST.exe 可以用hijackthis进行修复

我建议你用瑞星ＱＱ尾巴专杀工具查杀

【回复“jrsjrs”的帖子】O4 - HKCU\..\Run: [ctfnom.exe] C:\WINNT\SVOHOST.exe
这项有鬼。请把C:\WINNT\SVOHOST.exe打包传上来（如果能找到的话）.

在安全模式下.搞定

看看是不这个的变种？



Worm.Youda.d 瑞星17.36.31 版可查杀- -                                     
Worm.Youda.d
破坏方法：病毒采用Delphi编写。

病毒运行后有以下行为：
  将自己复制到%WINDIR%目录下，文件名为"svchost.exe"。

修改注册表以下键值以达到其自启动的目的：

HKEY_CLASSES_ROOT\exefile\shell\open\command
默认 ="%WINDIR%\SVCHOST.EXE "%1" %*"

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\Currentversion
\Run  "Microsoft"="%WINDIR%\SVCHOST.EXE"

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion
\Explorer\Advanced  "HideFileExt" = 0X00000001

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion
\Explorer\Advanced  "Hidden" = 0X00000002

查找并结束下进程：
pfw.exe
kvfw.exe
iamapp.exe
nmain.exe
freepp.EXE
freekav.EXE
freesys.EXE
Iparmor.exe
trojan_hunter.exe
Rfw.exe
KVMonXP.kxp
KVCenter.kxp
KvXP.kxp
KAVPFW.EXE
KWatch.EXE
KPfwSvc.EXE
KAVStart.exe
KMailMon.EXE
KAV32.EXE
关闭包含字符串"瑞星"、"病毒"、"杀毒"、"木马"、"金山毒霸"的窗口，并删除指定的反病毒软件和防火墙程序在注册表中的自启动项。

病毒会删除瑞星目录下的所有文件，感染可执行文件，枚举网络中可写的共享目录，试图将自己复制到这些目录下，为其远程控制端提供远程控制服务。
