用HijackThis扫描发现F2项
F2 - REG:system.ini: UserInit=C:\WINDOWS\System32\userinit.exe,C:\Documents and Settings\All Users\Application Data\Microsoft\Crypto\cgancal.exe

UserInit有以前没见过的cgancal.exe，
在安全模式下为
F2 - REG:system.ini: UserInit=C:\WINDOWS\System32\userinit.exe,C:\Documents and Settings\All Users\Application Data\Microsoft\Crypto\difd.exe
尝试在安全模式下改注册表为UserInit=C:\WINDOWS\System32\userinit.exe，改完后又自动变回去了。尝试删除这两个文件，结果又自动生成。

请问，这两个是什么文件啊？有什么危害么？

【回复“我无邪”的帖子】

按照你说的做了，还是不行。UserInit这项修复之后又自动生成了，cgancal.exe文件也是删除了又自动生成（安全模式下删过也不行）。
用你提供的System Repair Engineer也警告说UserInit注册值被改成非正常值。以下是扫描报告：
