那直接修复下不行吗

就我给我分析的，没发现什么问题,不过感觉你的IE工具装得太多了吧,如果你没怎么用他们的话，建议你把这些都删了吧

同意ls的，QQ插件还说的过去，这个百度超级搜霸有作用吗

楼主的我也遇到过，试了几次都干不掉
不过似乎对使用没有影响

这个该怎么解释呢?
R3 - Default URLSearchHook is missing
默认的搜索引擎没有了.

这个IE右键的菜单全部可以去除的

又是迅雷又是FlashGet,IE的加载项还真多,建议用360安全卫士修复一下(超级兔子修复也可)!
PS:这些软件在求助区的置顶帖都有(下载地址或下载链接)

删除右键菜单的内容

　　首先单击“开始”菜单中的“运行”命令，打开“运行”对话框，在“打开”栏里输入“regedit”，然后按“确定”。然后在打开的“注册表编辑器”窗口中，打开 HKEY_CURRENT_USER\Software\ Microsoft\Internet Explorer\MenuExt主键，在该主键下会有许多的子主键，这些子主键的名称就是显示在右键菜单中的命令，只需找到显示命令的那条主键条目，单击鼠标右键，在弹出的快捷菜单中选择“删除”即可。


楼主没有必要全部删除，我就是留着迅雷呢，这样下载东西时也方便。
