Arquivos estranhos no drive de compartilhamento samba4 criado pelo Windows 7 (svchost.exe)

Question

Em nosso disco de compartilhamento samba4, o Windows 7 parece criar alguns arquivos estranhos. Eles têm a seguinte estrutura e variam entre alguns megabytes e mais de 100 MB:

/path-to-share/t4vc
/path-to-share/t4vc.1
/path-to-share/t4vc.2
/path-to-share/t4f0
/path-to-share/t4f0.1
/path-to-share/t4f0.2

Até agora, consegui rastrear o usuário do Windows 7, que cria os arquivos e pesquisou com o Process Monitor. Uma olhada mais de perto no caminho do compartilhamento mostra algumas CreateFile das operações pelo svchost.exe .

Como posso descobrir para que servem os arquivos e o que o processo svchost faz?

As propriedades do evento estão me mostrando o seguinte comando:

C:\Windows\System32\svchost.exe -k LocalSystemNetworkRestricted

Você tem o módulo F-Secure (fshook64.dll) que está ligado ao processo com relação a isso?
