每次重启后瑞星都在内存里清除同一病毒，病毒名为Backdoor.Gpigeon.5.dq  文件为IEXPLORE.EXE，用灰鸽子检测器检测不到什么。想手工在WINNT里查找也没发现那几个典型文件？现在晕了，扫描一个日志上来请高手帮忙，先谢谢了

自然是Helpsrv.exe是灰鸽子，为什么我找不到它的文件在安全模式下只找到以下几个类似文件，但不敢确定它们是灰鸽子的文件
helpsrv.exe  c:\winnt  (有两个，还有一个在c:\winnt\system32下，正常模式下可以删除)
softkey.dll  c:\winnt\servicepackfiles\i386\jpn
mag_hook.dll  c:\winnt\system32
mag_hook.dll  c:\winnt\system32\dllcache
象网上说的那样，如果helpsrv.exe是灰鸽子，那么在winnt里还应该有helpsrv.dll,helpsrv_hook.dll,helpsrvkey.dll请帮我确定一下，会不会是其它的病毒？
