总是在系统盘自动产生一个new.exe文件，瑞星和防火墙都不能启动，不能玩中游，提示说客户端通信失败，QQ有时候自动关闭，其它基本正常。昨天在注册表删除了一个值为new.exe的键后就正常了，今天一重起又一样，在注册表了也找不到那个键值了。请教达人，究竟是什么原因？这是怎么一类病毒啊？谢谢

灰鸽子，看看查杀灰鸽子的帖子。

C:\WINDOWS\System32\NTdhcp.exe这就是你打不开杀毒软件的原因
打开任务管理器，结束进程NTdhcp.exe
删除隐藏文件%SYSTEM%\NTdhcp.exe
运行regedit.exe打开注册表编辑器，删除注册表启动项
HKEY_LOCAL_MACHINE\SoftWare\Microsoft\Windows\CurrentVersion\Run
下木马添加的值："NTdhcp"="%SYSTEM%\NTdhcp.exe"

首先运行任务管理器，查找并结束掉NTdhcp.exe进程按照病毒文件所在位置System\\NTdhcp.exe找到系统目录下的病毒文件，手工删除，运行REGEDIT注册表编辑器，定位到[HKEY_LOCALMACHINE\\Software\\Microsoft\\Windows\\CurrentVersion\\Run]，将RUN下面的键值"NTdhcp" = %SystemDir%\\NTdhcp.exe删除。
1、使用WINDOWS UPDATE功能自动更新系统补丁。
2、下载安装MHT文件下载执行漏洞补丁。MHT漏洞官方补丁下载地址：http://www.microsoft.com/technet/security/bulletin/MS04-013.mspx。
