可以自行修改主页，但无论怎么修改，包括设为空白页，但启动IE后被主页被锁定为“WWW.168tom.com”，光标指向快速启动栏的IE时提示亦为WWW.168tom.com。
用瑞星查杀未发现病毒，上网助手也未发现恶意代码，IE修复无效。
请各位大侠指教！！！

由于本人无法经常上论坛，哪位有什么高招麻烦发到：fangcl@126.com　　非常感谢！

我想上传LOG文件，但提示说文件格式不对（TXT文件和压缩文件都不行），怎么办？！

请帮忙分析一下，谢谢！

已按照“飞跃迷离”版主（感谢）所说的做了一遍，但是没发现以下文件：

C:\WINDOWS\Downloaded Program Files\barhelp22.0.dll
C:\WINDOWS\DOWNLO~1\IEBAR2~1.DLL
c:\ex.cab
c:\eied_s7.cab

　　但问题还是没有解决，不知还有什么高招？请赐教，谢了！

　　那就拜托了！

不好意思，补充一点，进入此网站时瑞星监测发现“Js.hta.StarPage"病毒，位置在IE临时文件夹，瑞星将其删除。

也需进入安全模式修复吗？

在安全模式下修复了，还是不行。

我的HOST文件被修改得一塌糊涂，
以下为host文件内容（由于篇幅所限，我将后面绝大部分的删去，内容基本类似），“218.5.72.87 ”正是恶意网站的IP，请问该如何修改？

127.0.0.1localhost
218.5.72.87 www.cnww.net
218.5.72.87 cnww.net
218.5.72.87 www.943721.com

218.5.72.87 www.943721.com

按版主方法进入安全模式进行修复，但故障依旧。重启后，

进入该网站时瑞星网页监控发现病毒，无法清除，只能删除。

病毒位置　C:\Documents and Settings\周丹\Local Settings\Temporary Internet Files\Content.IE5\6VAVY5YN\open[1].hta

进程名称　C:\WINDOWS\System32\mshta.exe -Embedding

病毒名称　Js.hta.StartPage

修复后host文件内容只剩下“127.0.0.1localhost”，但一上该恶意网站，马上就又被写入218.5.72.87 www.cnww.net
218.5.72.87 cnww.net
218.5.72.87 www.943721.com
218.5.72.87 943721.com
218.5.72.87 www.94265.com
。。。。。。

该恶意网站为WWW.168tom.com。我的IE一启动后就会自动链接到该网页，修改主页后也一样会链接。

在正常状态下手动把hosts文件修改保存后，紧接着重新打开马上又会被恶意修改。

请帮忙。
