有位网友的电脑最近开机时自动弹出一个空的记事本窗口,让偶帮忙检查看看。

http://endurer.ys168.com 下载 HijackThis 和 ProcView。

先用 HijackThis 扫描log,发现如下可疑项目:

/------
Logfile of HijackThis v1.99.1
Platform: Windows XP SP2 (WinNT 5.01.2600)
MSIE: Internet Explorer v6.00 SP2 (6.00.2900.2180)

Running processes:
C:/windows/system32/wincfgs.exe
C:/WINDOWS/KB20060111.exe

F3 - REG:win.ini: load=C:/windows/system32/wincfgs.exe
------/

运行ProcView,让进程按修改时间逆序排列,发现:
C:/WINDOWS/KB20060111.exe 排在第 1 位,修改时间为:2006-10-27 20:47,图标与Windows自带的记事本相同。
c:/windows/system32/wincfgs.exe 排在第 3 位,修改时间为:2006-10-27 20:47,图标为一个黄色问号。

c:/windows/system32/wincfgs.exe,文件大小为 47,104 字节,上传在线扫描,都报了:
