我用的是秋老大的XP，我发现D盘多了两不明文件，我把它删除，重启后又有，里面的内容分别为：
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced\Folder\Hidden\SHOWALL]
"CheckedValue"=dword:00000000
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{871C5380-42A0-1069-A2EA-08002B30309D}\shell\OpenHomePage\command]
@=hex(2):63,00,3a,00,5c,00,70,00,72,00,6f,00,67,00,72,00,61,00,6d,00,20,00,66,\
00,69,00,6c,00,65,00,73,00,5c,00,69,00,6e,00,74,00,65,00,72,00,6e,00,65,00,\
74,00,20,00,65,00,78,00,70,00,6c,00,6f,00,72,00,65,00,72,00,5c,00,69,00,65,\
00,78,00,70,00,6c,00,6f,00,72,00,65,00,2e,00,65,00,78,00,65,00,20,00,77,00,\
77,00,77,00,2e,00,68,00,61,00,30,00,31,00,32,00,33,00,2e,00,69,00,6e,00,00,\
00
请问，这是什么东西，怎样完全删除？
