NIS 2011 Firewall advanced

Hi everyone,
using NIS 2011 Italian version on a Windows 32bit pc, in NIS settings I turned ON manual control on advanced firewall events. Today I checked the allowed files under “direct network access” and I founded many program like lsass.exe, hsplayer.exe, explorer.exe that I never allowed to “direct network acces”. NIS never showed me a dialog box to choose.

Is this normal or I have a problem?

Thanks in advance for replies.
