我认为你这个问题在卸载了三七二一，雅虎助手后，会不药而愈
你且试试
下载超级兔子。
http://www.pctutu.com/srmsdown.asp
安装好后，打开“超级兔子优化王”“专业卸载,卸载所有提示的垃圾软件，卸载是不要打开任何浏览窗口。卸载不了可以重启后再去卸载。
卸载不了，可以考虑进入安全模式

打开一个IE窗口，工具，internte选项，点“删除文件”弹出一个窗口勾选“删除所有脱机内容”删除cookies,确定。
打开System Repair Engineer（也就是你的扫描日志软件SREng.exe），使用“系统修复，Internet Explorer”“全选”“修复"看看能不能解决问题。

以上是扫描报告,请无邪帮忙
