I'm trying to record data of all the processes that establish connections from my PC for security issues, I tried to do netstat -bn 1 > stats.txt, also tried to make a log file with CurrPorts, TCPView from what I've seen doesn't even have an option to log changes,

but what's wierder is that they all occasionaly show processes as "unknown", CurrPorts seems to be the best so far but also lists some unknown processes.

1.How is it possible that processes have unknown paths? doesn't the system know the path of any process that establishes a connection?

2.Is there another tool I haven't used or some other way to log the processes that establish connections in a clear way and with the paths of all the processes?

I had the same issue using CurrPorts, except I had maybe 20 of them. I noticed the IP addresses and names of some: Comodo and Google, for starters. My guess then was that it was my DNS settings. So I changed them and ALL of those entries disappeared. I'm unable to directly answer your question. But if it helps you to at least be able to possibly identify and rid yourself of those entries, perhaps my experience will help you. – Alex Nov 5 '15 at 17:30

Short lived processes or processes exiting during the sampling might be missed by your commands.
