我的ie首页被改成这个网址了http://www.martfinder.com/2/
已经用过3721 超级兔子  hijackthis （扫描报告有C:\WINNT\windows.dat）和CWShredder
都无效
真是郁闷死人了
哪位高人曾经遇到过，请给予指点，谢谢

感谢楼上的建议！！
以下是扫描报告，其中O19 - User stylesheet: D:\WINNT\windows.dat  我怎么都删不掉它~~~

还是不行
1）
我首先用HijackThis 扫描后，试图清除第019项，但无法清楚，重新扫描后依然存在
2）
我改用CWShredder尝试清除，但扫描结果“CWS was not found on system”
3）
重起计算机进安全模式，HijackThis扫描后竟然没有第019项，改用CWShredder尝试清除，但扫描结果同样是“CWS was not found on system”  于是我手工删除d:\winnt\windows.exe
4）重新正常启动，d:\winnt\windows.exe 重新出现，问题依旧~~~~
