各位大哥，我的电脑中毒了，症状：IE打开后无法显示内容，我检查了连接主机PING的通，网关也没问题。用系统扫描工具扫描的情况如下：

你的意思是说打不开网页，请问能上QQ吗？

开始→运行→输入services.msc，打开“服务”→查找Microsoft NetWork FireWall Services →双击→启动类型→禁止→停止→应用→确定。禁止Microsoft NetWork FireWall Services这个服务

关闭所有浏览窗口以及一些不必要的程序
运行Hijackthis，扫描结束后在下列选项前打上勾，然后选"修复"

请下载 System Repair Engineer，使用“智能扫描”，按下“扫描”按钮进行扫描，扫描完成后按下“保存报告”按钮保存报告日志文件（SREng.LOG），把保存的报告日志文件内容复制-粘贴上来
下载网址

日志一次粘不完，分次粘完，请不要修改。

QQ不知道能不能上，我机子没安装QQ。哦，还有一个症状就是进入系统时会弹出一个乱码提示框。现日志文件扫描如下：2006-09-15,21:45:40
