一、每次你都要做的 ? 重设Internet选项：
1. 清Internet Explorer的临时文件
2. 重设安全级别为默认级别
3. Cookie的设置也设为默认级别
4. 程序关联也重置
5. 把高级设置也重置
6. 有时候把”启用第三方浏览器扩展”禁止会解决一些问题
二、有些情况下是由于一些DLL没有被正确注册
大概可以分成以下几类：
脚本出错：
-----------------------------------
regsvr32 scrrun.dll
regsvr32 msxml.dll
regsvr32 mshtml.dll
regsvr32 msjava.dll
regsvr32 jscript.dll
连接打不开：
-----------------------------------
regsvr32 urlmon.dll
页面显示问题：
----------------------------------
regsvr32 shdocvw.dll
regsvr32 browseui.dll
安全站点打不开：
---------------------------------
regsvr32 softpub.dll
regsvr32 wintrust.dll
regsvr32 initpki.dll
三、如果是IE出错，大多数情况下是由于第三方Plug-in造成的。IE本身出错的情况是很少见的。
1. 去Spyware是你发现IE老是出错或者你的主页老是被改掉时第一个要用的常用的去Spyware的免费工具：
Ad-Aware: http://www.lavasoft.de/support/download
Spybot S&D: http://beam.to/spybotsd
CWShredder: http://www.spywareinfo.com/~merijn/files/CWShredder.exe
注意在运行这些程序的时候要把IE和Explorer全部关掉，因为大多数Spyware的进程是绑定到这两个和Windows Shell有关的process上的。同时注意要注意把这些工具更新到最新的特征库。Spyware和virus一样也要更新定义库的。
另外一些传统上的防病毒软件现在也能杀一部分spyware。下面有几个免费的在线服务：
Trendmicro: http://housecall.trendmicro.com/
BitDefebder: http://www.bitdefender.com/scan/licence.php
Panda: http://www.pandasoftware.com/activescan/
2. 如果spyware不能自动去除，可能就需要你手工清除。最常用的工具有：
HijackThis: http://www.majorgeeks.com/download3155.html or http://www.spywareinfo.com/~merijn/files/HijackThis.exe
它会扫描当前的系统状态。下面是一个例子：
