请问哪里有问题？谢谢

这项是个木马。请把C:\WINNT\svch0st.exe打包传上来看看。

这两项我不知道是什么。你自己知道吗？

另：建议卸载“上网助手”（昨天报纸已经公布——3721列在“流氓软件”的榜首）

哪两项我也不知道是什么。请问怎么上传呀？

用WINRAR或WINZIP将那个文件打包。将打好的包作为回帖附件传上来（和传图片的方法一样——附件）。

请查看

传错了。我要的是 C:\WINNT\svch0st.exe（文件名中的那个“0”是数字，不是字母）。这个文件可能是隐藏的。请在“文件夹选项”中勾选“显示系统文件夹”、“显示所有文件和文件夹”，然后，在安全模式下找。注意：这个文件在C:\WINNT\下。

是这个吗？

还是不对。你传的是个正常的svchost.exe。

好，我再找一找
