电脑感染上winlogon.exe病毒了怎么办？

电脑在浏览一些不安全网站的时候非常容易感染病毒，随着网络的发展，病毒也变得越来越多样化。近日一位网友突然发现自己的电脑感染上一个名为“winlogon.exe”的病毒，对此该怎么办呢？本文就给大家介绍手动清除winlogon.exe电脑病毒的方法。

这只鸽子提示：中招后，贴日志求助的日子即将结束！做好系统基础安全防护是每个用户的当务之急。“基础安全防护”绝不仅仅是打几个补丁的问题。熟悉一两个性能好的安全软件的使用也是必要的。否则，中招后，你自己就着急吧！

这只鸽子的要害是c:windows/winlogon.dll。如果想办法禁止这个dll加载运行，鸽子的文件全部可见图1：

screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='点击这儿打开新的窗口';}" resized="true">

这只鸽子的要害是这个c:windowswinlogon.dll。

如果用SSM禁止c:windowswinlogon.dll加载运行，则这只鸽子的文件全部可见。

这是Movgear.exe中捆绑的一只灰鸽子（Movgear.exe样本来自安全12公里）。winlogon.exe的MD5值为：2de9f62c2b405e16cb66773747cf0f2d。

一、自Movgear.exe中提取winlogon.exe并将其植入系统后，autoruns、HijackThis、SREng日志中均无任何异常发现。

winlogon.exe释放的文件有：

1、c:windowswinlogon.exe

2、c:windowswinlogon.dll

3、c:windowswinlogonKey.dll

这两个dll插入IE浏览器进程。

即使不打开IE浏览器，IceSword的进程列表中依然可见iexplore.exe。

c:windowswinlogonKey.dll动态跟踪所有应用程序进程（一旦开启，立即插入。）

注意：即使显示隐藏文件，用WINDOWS的资源管理器也看不到灰鸽子释放的这三个文件。用IceSword才能看到。

二、注册表改动包括：

1、在HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServices

添加：winlogon.exe（指向c:windowswinlogon.exe）

2、在HKEY_USERS.DEFAULTSoftwareMicrosoftInternet ExplorerExtensionsCmdMapping

添加：

"{92780B25-18CC-41C8-B9BE-3C9C571A8263}"=dword:00002002 "{DEDEB80D-FA35-45d9-9460-4983E5A8AFE6}"=dword:00002002 "{FB5F1910-F110-11d2-BB9E-00C04F795683}"=dword:00002001

3、在HKEY_USERS.DEFAULTSoftwareMicrosoftInternetConnectionWizard

添加："Completed"=hex:01，00，00，00

4、在HKEY_USERS.DEFAULTSoftwareMicrosoftInternetExplorerToolbarWebBrowser

添加：

01"ITBarLayout"=hex:11,00,00,00,5c,00,00,00,00,00,00,00,34,00,00,00,1f,00,00,00,56,0200,00,00,01,00,00,00,20,07,00,00,a0,0f,00,00,05,00,00,00,62,05,0300,00,26,00,00,00,02,00,00,00,21,07,00,00,a0,0f,00,00,04,00,00,0400,21,01,00,00,a0,0f,00,00,03,00,00,00,20,03,00,00,00,00,00,00,0500,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,0600,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,0700,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,0800,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,0900,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,1000,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,1100,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,1200,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,1300,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,1400,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,1500,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,1600,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,1700,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,1800,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,1900,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,2000,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,2100,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,2200,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,2300,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,2400,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,2500,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,2600,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,2700,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,0028"{01E04581-4EEE-11D0-BFE9-00AA005B4383}"=hex:81,45,e0,01,ee,4e,d0,11,bf,e9,00,aa,00,5b,43,83,10,00,00,00,00,2900,00,00,01,e0,32,f4,01,00,00,0030"{0E5CBF21-D15F-11D0-8301-00AA005B4383}"=hex:21,bf,5c,0e,5f,d1,d0,11,83,01,00,aa,00,5b,43,83,22,00,1c,00,08,3100,00,00,06,00,00,00,01,00,00,00,00,00,00,00,00,00,00,00,00,00,3200,00,4c,00,00,00,01,14,02,00,00,00,00,00,c0,00,00,00,00,00,00,3346,81,00,00,00,10,00,00,00,a0,8f,ff,ba,9d,d4,c6,01,00,9e,02,bb,349d,d4,c6,01,a0,8f,ff,ba,9d,d4,c6,01,00,00,00,00,00,00,00,00,01,3500,00,00,00,00,00,00,00,00,00,00,00,00,00,00,5d,01,14,00,1f,50,36e0,4f,d0,20,ea,3a,69,10,a2,d8,08,00,2b,30,30,9d,19,00,2f,43,3a,375c,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,5c,3800,31,00,00,00,00,00,3a,31,09,3c,10,00,44,4f,43,55,4d,45,7e,31,3900,00,44,00,03,00,04,00,ef,be,3a,31,9c,36,2a,35,f7,29,14,00,00,4000,44,00,6f,00,63,00,75,00,6d,00,65,00,6e,00,74,00,73,00,20,00,4161,00,6e,00,64,00,20,00,53,00,65,00,74,00,74,00,69,00,6e,00,67,4200,73,00,00,00,18,00,4c,00,31,00,00,00,00,00,2a,35,cb,2e,16,00,434e,45,54,57,4f,52,7e,31,00,00,34,00,03,00,04,00,ef,be,3a,31,11,4439,2a,35,cb,2e,14,00,00,00,4e,00,65,00,74,00,77,00,6f,00,72,00,456b,00,53,00,65,00,72,00,76,00,69,00,63,00,65,00,00,00,18,00,56,4600,31,00,00,00,00,00,2a,35,cb,2e,11,00,46,41,56,4f,52,49,7e,31,4700,00,3e,00,03,00,04,00,ef,be,2a,35,cb,2e,2a,35,cb,2e,14,00,28,4800,46,00,61,00,76,00,6f,00,72,00,69,00,74,00,65,00,73,00,00,00,4940,73,68,65,6c,6c,33,32,2e,64,6c,6c,2c,2d,31,32,36,39,33,00,18,5000,30,00,35,00,00,00,00,00,2a,35,f1,2e,10,00,fe,94,a5,63,00,00,511c,00,03,00,04,00,ef,be,2a,35,f1,2e,2a,35,f1,2e,14,00,00,00,fe,5294,a5,63,00,00,14,00,00,00,60,00,00,00,03,00,00,a0,58,00,00,00,5300,00,00,00,6c,69,6e,62,61,6f,68,65,00,00,00,00,00,00,00,00,1e,548c,63,4d,34,72,b3,48,8a,de,83,67,8f,38,be,10,b1,a9,fd,89,90,40,55db,11,b2,29,00,d0,59,c0,b8,59,1e,8c,63,4d,34,72,b3,48,8a,de,83,5667,8f,38,be,10,b1,a9,fd,89,90,40,db,11,b2,29,00,d0,59,c0,b8,59,5700,00,00,00复制代码"ITBarLayout"=hex:11,00,00,00,5c,00,00,00,00,00,00,00,34,00,00,00,1f,00,00,00,56,00,00,00,01,00,00,00,20,07,00,00,a0,0f,00,00,05,00,00,00,62,05,00,00,26,00,00,00,02,00,00,00,21,07,00,00,a0,0f,00,00,04,00,00,00,21,01,00,00,a0,0f,00,00,03,00,00,00,20,03,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,0

7、在HKEY_USERS.DEFAULTSoftwareMicrosoftWindowsCurrentVersionExplorerMenuOrderFavorites链接

添加："Order"=hex:08，00，00，00，02，00，00，00，0c，00，00，00，01，00，00，00，00，00，00，00

三、进行上述观察后，重启系统。

重启后，卡巴斯基报警（我的卡巴斯基为启动加载）：发现灰鸽子。但卡巴斯基仅仅将c:windowswinlogon.dll删除；c:windowswinlogon.exe和c:windowswinlogonKey.dll卡巴斯基并不报毒。汗！！卡巴斯基越来越不争气了另外发现其winlogonKey.log文件。文件内容为：

#？》。？：4？74;

四、查杀流程：

1、打开注册表编辑器，展开HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServices

删除灰鸽子的服务项：winlogon.exe

2、重启系统。用IceSword找到并删除鸽子释放的那三个文件。

4、清理注册表（删除鸽子添加的注册表项）。

五、查杀方法：安全模式下操作

删除文件

C:WINDOWSsystem32AddrConfig.bin

C:WINDOWSsystem32oobedata

C:WINDOWSsystem32wbemddes

C:WINDOWSsystem32wbemkbd101ab.dll

以上便是手动清除winlogon.exe电脑病毒的详细操作，由于操作起来步骤比较多，所以用户在操作的时候一定要注意，不要删除错了注册表，以免影响到其它功能无法正常使用。
