我的电脑每次上网的时候途中就会跳出什么搜易网和学英语的网站,下了超级兔子,还是删不了,不仅如此,而且更糟的事,每次我用IE修复，超级兔子还好点，用黄山和WIN优化大师就会先黑屏再蓝屏，出现一串英文，如下：
A problem has been detected and windows has been shut down to prevent damage to your computer
A driver has overrun a stack-based buffer .This overrun could potentially allo user to gain control of this machine .If this is the first time you ’ve seen this stop error screen ,restart your computer. If this appears again ,follow these steps
Check to make sure any new hardware is properly installed .If this is a new installation,ask your hardware or software manufcturer for any windows updates you might need.
If problem continue ,diable or remove any newly installed hardware or software. Disable  BIOS memory options such as caching or shadowing .If you need to use safe Mode to remove or disable components restart your computer press F8 to select Advanced startup options and then select safe Mode
Technical information ***STOP:0X000000F7(0X00000000,0X00000000,0X00000000, 0X00000000)
我用瑞星杀过毒，杀掉4个木马，但是杀完了还这样。

现在发现好像是只要我试图去卸载一搜工具栏就会这样

试过了
