O2 - BHO: InsIII - {DDDE2452-AF9E-4577-AE6C-465DBCB54D49} - C:\WINDOWS\system32\opngl16.dll
删除
C:\WINDOWS\system32\opngl16.dll

关于无法修改主页请检查您是否开启了某些软件的ie保护功能

谢谢版主的指点，
不过还有一事相求，就是opngl16.dll这个文件删不掉，是不是要在安全模式下删除？
还有就是怎样检查是否开启了软件的ie保护功能？

【回复“大笨熊都都”的帖子】
请在安全模式下删除这个C:\WINDOWS\system32\opngl16.dll。

怎样检查是否开启了某些软件的IE保护功能？？还请指点，多谢了

您是否使用了3721、超级兔子、卡卡助手等ie工具，请检查他们的默认选项
