如何显示所有文件和文件夹(隐含及系统保护)
windows 98
在“我的电脑”或“windows资源管理器”窗口菜单栏中点击“查看”>>“文件夹选项...”,在出现的“文件夹选项”对话框中点“查看”选项卡,然后在其中点选“显示所有文件”,最后“确定”。其中去掉“隐藏已知文件类型的扩展名”前的勾,则显示所有文件的扩展名。
如图所示:
screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor="hand"; this.alt="click here to open new window\nctrl+mouse wheel to zoom in/out";}" nclick="if(!this.resized) {return true;} else {window.open("/artpic/beyondpic/2006-5/18/showall98.gif");}" src="/artpic/beyondpic/2006-5/18/showall98.gif" nload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt="click here to open new window\nctrl+mouse wheel to zoom in/out";}" border=0>
windows xp
在“我的电脑”或“windows资源管理器”窗口菜单栏中点击“工具”>>“文件夹选项...”,在出现的“文件夹选项”对话框中点“查看”选项卡,然后在其中去掉“隐藏受保护的操作系统文件”前的勾,点选“显示所有文件和文件夹”,最后“确定”。其中去掉“隐藏已知文件类型的扩展名”前的勾,则显示所有文件的扩展名。windows 2000与windows xp操作类似。
如图所示:

s update
1.windows update为windows系统自带的功能,用于windows系统的在线更新。
要启动windows update,可以从“开始”菜单、ie菜单栏上的“工具”菜单中的“windows update”等地方点击运行windows update。
screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor="hand"; this.alt="click here to open new window\nctrl+mouse wheel to zoom in/out";}" nclick="if(!this.resized) {return true;} else {window.open("/artpic/beyondpic/2006-5/18/wupd01.gif");}" src="/artpic/beyondpic/2006-5/18/wupd01.gif" nload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt="click here to open new window\nctrl+mouse wheel to zoom in/out";}" border=0>
2. 启动windows update后,如图所示,首先ms会搜索当前系统中的windows update版本,如果版本过旧,则会首先要求用户安装新版本的windows update。
进入“欢迎界面”后,点击图中“查看以寻找更新”开始搜索系统所需要安装的关键更新、service pack及一些其它更新。

>从注册表编辑器中删除病毒文件的自启动项
打开注册表编辑器:“开始”>>“运行”,输入“regedit”,点击“确定”打开注册表编辑器。
在这里为了能结合实际地说明一些问题,特别介绍删除病毒lovgate.w (aka supnot.w)的自启动项。(以windows 2000为例)
一般病毒经常会将自己的自启动项加在注册表的hkey_local_machine\software\microsoft\windows\currentversion\run下,这也是最常见的一个自启动项位置,如图:
screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor="hand"; this.alt="click here to open new window\nctrl+mouse wheel to zoom in/out";}" nclick="if(!this.resized) {return true;} else {window.open("/artpic/beyondpic/2006-5/18/run1.gif");}" src="/artpic/beyondpic/2006-5/18/run1.gif" nload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt="click here to open new window\nctrl+mouse wheel to zoom in/out";}" border=0>
对于病毒的自启动项,我们一般可以直接删除。
注册表的hkey_local_machine\software\microsoft\windows\currentversion\runonce和hkey_local_machine\software\microsoft\windows\currentversion\runservices也是病毒经常添加自启动项的地方,如图:
screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor="hand"; this.alt="click here to open new window\nctrl+mouse wheel to zoom in/out";}" nclick="if(!this.resized) {return true;} else {window.open("/artpic/beyondpic/2006-5/18/run4.gif");}" src="/artpic/beyondpic/2006-5/18/run4.gif" nload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt="click here to open new window\nctrl+mouse wheel to zoom in/out";}" border=0>
另外,注册表的hkey_current_user\software\microsoft\windows nt\currentversion\windows下的run和load也会被病毒程序利用起来加上它们的自启动项,只不过不是非常多见,所以有些用户也不十分清楚它在注册表编辑器中的位置,不一定能在注册表编辑器中找到这里,这个时候,我们可以使用菜单“编辑”>>“查找”功能来查找一下我们所要找的病毒自启动信息,如图,我们输入病毒文件的完整文件名来进行查找:
screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor="hand"; this.alt="click here to open new window\nctrl+mouse wheel to zoom in/out";}" nclick="if(!this.resized) {return true;} else {window.open("/artpic/beyondpic/2006-5/18/run2.gif");}" src="/artpic/beyondpic/2006-5/18/run2.gif" nload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt="click here to open new window\nctrl+mouse wheel to zoom in/out";}" border=0>

通过查找,我们可以很轻松地找到它的自启动信息和其它一些相关信息。
screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor="hand"; this.alt="click here to open new window\nctrl+mouse wheel to zoom in/out";}" nclick="if(!this.resized) {return true;} else {window.open("/artpic/beyondpic/2006-5/18/run3.gif");}" src="/artpic/beyondpic/2006-5/18/run3.gif" nload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt="click here to open new window\nctrl+mouse wheel to zoom in/out";}" border=0>
使用“系统配置实用程序”来管理自启动项信息
我们知道在windows 9x和windows xp中都有一个叫作“msconfig”的东西,这个就是“系统配置实用程序”,通过它,我们可以方便地管理一些程序的自启动信息。
打开系统配置实用程序:“开始”>>“运行”,输入“msconfig”,点击“确定”打开系统配置实用程序。
在“系统配置实用程序”的“启动”选项页上我们可以看到有一个启动程序列表,它们前面的勾表示它们是否在系统启动时也随系统同时启动。一般对于病毒的自启动项,我们可以在这里将它们前面的勾去掉,如图:
screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor="hand"; this.alt="click here to open new window\nctrl+mouse wheel to zoom in/out";}" nclick="if(!this.resized) {return true;} else {window.open("/artpic/beyondpic/2006-5/18/run5.gif");}" src="/artpic/beyondpic/2006-5/18/run5.gif" nload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt="click here to open new window\nctrl+mouse wheel to zoom in/out";}" border=0>
另外,在下图中所示的位置也有可能成为病毒加载自启动项的地方,如果被病毒修改了,我们一般可以直接修改这里:
screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor="hand"; this.alt="click here to open new window\nctrl+mouse wheel to zoom in/out";}" nclick="if(!this.resized) {return true;} else {window.open("/artpic/beyondpic/2006-5/18/run6.gif");}" src="/artpic/beyondpic/2006-5/18/run6.gif" nload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt="click here to open new window\nctrl+mouse wheel to zoom in/out";}" border=0>

使用第三方工具
除了通过使用“系统配置实用程序”和直接修改系统注册表的方法来去除病毒的自启动项外,我们还可以使用一些第三方的小工具来去掉或编辑这些启动项,比如hijackthis等等。
小技巧
windows 9x和windows xp中的msconfig.exe程序也可以在windows 2000下直接运行,同样可以显示修改windows 2000中的“启动”信息。
