系统中运行的程序，都会有一个与之对应的进程。木马、病毒同样如此。一些用户在“任务管理器”的“标程”标签中经常会发现一些来历不明的进程，因此毫不犹豫的就将它们中止。但是在中止的时候却出现了问题，无法关闭这些正在运行的进程！这该怎么办呢？看看我们是如何强制关闭这些进程的吧！
一、普通进程——Taskkill
对于一般的病毒，在无法直接中止时，大家可以在任务管理器的进程列表中记录下进程的名称。再打开“运行”窗口，输入“CMD”回车打开命令提示符窗口，在命令提示符下输入“Taskkill /im /f 要关闭的进程名”，输入之后回车，你就会看到成功终止进程的提示信息，再返回“进程”标签中，已经看不到该进程了。
二、顽固病毒——Ntsd
使用taskkill地结束进程时，有时会碰到一些比较顽固的病毒，其生成的进程很难被关闭。这时，就可以试试借助ntsd命令来解决。
首先在任务管理器中打开“查看”菜单下的“选择列”命令，在打开的窗口中选中“PID（进程标志符）”，保存设置后返回任务管理器，在“进程”标签中找到要关闭的进程，并记录下PID列该进程的值。
按照前面的方法打开命令提示符窗口，输入“ntsd -c q -p 进程的PID值”，回车之后即会在一个弹出的DOS窗口中强制关闭该进程。
通过上面的两招，我们再也不用担心那些顽固的病毒对系统造成破坏了，不过在这里要提醒你，如果怀疑中了病毒、木马，仅仅是关闭进程并不能彻底解决问题，因为重新启动后进程又会运行，最好的方法就是借助专门的杀毒软件和木马清除工具进行清查。
问:怎么才能关掉一个用任务管理器关不了的进程？我前段时间发现我的机子里多了一个进程，只要开机就在，我用任务管理器却怎么关也关不了
答1:杀进程很容易，随便找个工具都行。比如IceSword。关键是找到这个进程的启动方式，不然下次重启它又出来了。顺便教大家一招狠的。其实用Windows自带的工具就能杀大部分进程：
c:>ntsd -c q -p PID
只有System、SMSS.EXE和CSRSS.EXE不能杀。前两个是纯内核态的，最后那个是Win32子系统，ntsd本身需要它。ntsd从2000开始就是系统自带的用户态调试工具。被调试器附着(attach)的进程会随调试器一起退出，所以可以用来在命令行下终止进程。使用ntsd自动就获得了debug权限，从而能杀掉大部分的进程。ntsd会新开一个调试窗口，本来在纯命令行下无法控制，但如果只是简单的命令，比如退出(q)，用-c参数从命令行传递就行了。NtsdNtsd
按照惯例也向软件开发人员提供。只有系统开发人员使用此命令。有关详细信息，请参阅 NTSD
中所附的帮助文件。用法:开个cmd.exe窗口，输入：
ntsd -c q -p PID
把最后那个PID，改成你要终止的进程的ID。如果你不知道进程的ID，任务管理器－>进程选项卡－>查看－>选择列－>勾上”PID（进程标识符）”，然后就能看见了。
答2：xp下还有两个好东东tasklist和tskill。tasklist能列出所有的进程，和相应的信息。tskill能查杀进程，语法很简单：tskill程序名！！
