I hope you don't mind answering some questions from a computer illiterate.

Without troubling you for too much detail, basically what are

NT Kernel & System (C:\Windows\system32\ntoskrnl.exe)

Application Layer Gateway Service(C:\Windows\system32\alg.exe)

LSA Shell (Export Version)(C:\Windows\system32\lsass.exe)

Client Server Runtime Process(C:\Windows\system32\csrss.exe)

Microsoft Synchronization Manager(C:\Windows\system32\mobsync.exe) ?

Should they have unfettered access through my firewall?
What dangers are there to let them through my firewall?

I don't know * about this stuff.

There's a list of what the various system files are for here (http://www.securemost.com/prs_lib/ntoskrnl_exe.htm).

There's generally no reason for most of these to need Internet access.

Thank you very much for the link.

It looks like a great resource. I looked at it briefly, and I'm sure I'll read more.
