Port 0 Inbound connections blocked. What is this port?

[GarthH]

I'm receiving inbound connections blocked on Port 0.   What is this port and can I block these connections using Windows Firewall?  I'm not familiar with this port #

Let's get the info to get the process started. Be aware it will take many steps and scans to fully remove pesky malware.

Please respond to all future instructions from your helper in a timely manner.

Please do the following so that we may take a closer look at your system for any possible infections.

Do these 2 steps FIRST so that files and folders are set to SHOW, plus also, Turn OFF Windows Fast Start.

This one was taken after the restart.  I was unable to see an option to disable Fast-Startup (Windows Server 2016) and i'm not comfortable adjusting the rembst-grab-results.zipgistry directly at this point
