我的机子每次开机时都设置了用瑞星扫内存和引导区,前几天每次都会发现有"backdoor.Gpigeon.pi"病毒,显示是已清除,可是下次开机时又会有了,从今天开始又多了一个"backdoor.Gpigeon.ubj",我想请教一下,是不是灰鸽子啊?我该怎么办呢?

我刚才看了许多关于灰鸽子的贴子,可还是不知道该如何办!因为我搜索不到相关文件,请各位高手不吝赐教!

刚才用HiJackThis扫描一下,如下,请帮我看看该怎么做才能清除!谢谢啦!

是不是倒数第二个啊??该怎么清除呢?

重新启动到安全模式（进入安全模式的方法:重新启动电脑, 开机自动检测完后, 按[F8]键(可以一直按到启动菜单出来为止), 选择安全模式(Safe Mode)进入Windows。）

请关闭所有IE界面，重新使用HijackThis扫描一次，选中下面建议修复的项目，让HijackThis修复，修复前请允许HijackThis保留备份。（如果楼主知道是安全的可以不必勾选）

然后打开我的电脑→再点工具→打开文件夹选项→查看→把隐藏受保护的系统文件（推荐）和隐藏已知文件类型的扩展名的勾去掉→再显示所有文件→找到以下文件并删除：(如果有的话)
C:\WINDOWS\DOWNLO~1\IEBAR2~1.DLL
