Prec = 0; Scale = 0) [{$ad$}　　Windows系统的Svchost.exe和Explorer.exe是非常重要的两种进程，上次我们介绍了Explorer.exe进程的应用技巧，今天我们介绍Svchost.exe进程的特点以及在各个操作系统中的应用。　

　　Svchost.exe是NT核心系统的非常重要的进程，对于2000、XP来说，不可或缺。很多病毒、木马也会调用它。所以，深入了解这个程序，是玩电脑的必修课之一。

　　大家对Windows操作系统一定不陌生，但你是否注意到系统中“Svchost.exe”这个文件呢?细心的朋友会发现Windows中存在多个 “Svchost”进程(通过“ctrl+alt+del”键打开任务管理器，这里的“进程”标签中就可看到了)，为什么会这样呢?下面就来揭开它神秘的面纱。

　　在基于NT内核的Windows操作系统家族中，不同版本的Windows系统，存在不同数量的“Svchost”进程，用户使用“任务管理器”可查看其进程数目。一般来说，Win 2000有两个Svchost进程，Win XP中则有四个或四个以上的Svchost进程(以后看到系统中有多个这种进程，千万别立即判定系统有病毒了哟)，而Win 2003 server中则更多。这些Svchost进程提供很多系统服务，如：rpcss服务(remote procedure call)、dmserver服务(logical disk manager)、dhcp服务(dhcp clieNT)等。〕

　　查看Svchost中的多个服务

　　如果要了解每个Svchost进程到底提供了多少系统服务，可以在Win 2000的命令提示符窗口中输入“tlist -s”命令来查看，该命令是Win 2000 support tools提供的。在Win XP则使用“tasklist /svc”命令。

　　Windows系统进程分为独立进程和共享进程两种，“Svchost.exe”文件存在于“%systemroot% system32”目录下，它属于共享进程。随着Windows系统服务不断增多，为了节省系统资源，微软把很多服务做成共享方式，交由 Svchost.exe进程来启动。

　　但Svchost进程只作为服务宿主，并不能实现任何服务功能，即它只能提供条件让其他服务在这里被启动，而它自己却不能给用户提供任何服务。那这些服务是如何实现的呢?

　　原来这些系统服务是以动态链接库(dll)形式实现的，它们把可执行程序指向 Svchost，由Svchost调用相应服务的动态链接库来启动服务。那Svchost又怎么知道某个系统服务该调用哪个动态链接库呢?这是通过系统服务在注册表中设置的参数来实现。

　　从启动参数中可见服务是靠Svchost来启动的。

　　查看Svchost中是否有病毒进程

　　因为Svchost进程启动各种服务，所以病毒、木马也想尽办法来利用它，企图利用它的特性来迷惑用户，达到感染、入侵、破坏的目的。但Windows系统存在多个Svchost进程是很正常的，在受感染的机器中到底哪个是病毒进程呢?这里仅举一例来说明。

　　假设Windows XP系统被病毒感染了。正常的Svchost文件存在于“c:\Windows\system32”目录下，如果发现该文件出现在其他目录下就要小心了。病毒存在于“c:\Windows\system32\Wins”目录中，因此使用进程管理器查看Svchost进程的执行文件路径就很容易发现系统是否感染了病毒。

　　Windows系统自带的任务管理器不能够查看进程的路径，可以使用第三方进程管理软件，通过这些工具就可很容易地查看到所有的Svchost进程的执行文件路径，一旦发现其执行路径为不平常的位置就应该马上进行检测和处理。
