The only guaranteed way is to back up and reinstall.
Sometimes, and only sometimes, you can try the following:
Full scan with your Anti Virus.
Download, install and run Process Explorer from Microsoft Sysinternals.
Look under the left side Explorer tree for alphanumeric processes.
Kill these and do NOT restart.
Scan completely with Malwarebytes.
Restart.
See now if the virus has been stopped.

The process will have the name or more likely an alphanumeric process name. That is the only way you can find it.

John,
I notice the 1st alert says the F7AE566F. exe was accessed from the remote system xxx.xxx.xxx.62. The Trojan named Artemis!716293B3EB20 was detected and deleted. Could this be the machine that is sending it out? After that I'm go alerts that other machines also have been hit from remote systems, but have been deleted.

You need to check each machine with Process Explorer and make sure it is not running.
Also get Autoruns (Sysinternals) and make sure it is not trying to start on any machine.

John,
When I run the Process Explorer I don't see any aphanumeric proccesses, but when I run the Autoruns, I'm seeing lots of alpha numeric stuff.

In Autoruns, you see plain, red, and yellow areas. Delete all the yellow, close out, restart and test.
Restart and see if the malware pops up again.
Also run Autoruns again and see if it Installed itself again

John,
Upended back up Autoruns and didn't see the alpha numeric yellow processes running.
Do I continue to do this on all the other computers and do I have to logged on as that user of the computer or can I log on as myself on their computer to remove the items?

Some generic advise: disconnect systems one by one from the network and observe when the hits stop. Then scan that PC (or better reinstall it).
If removal does not work, you are going to have to backup machines and reinstall Windows.

Are all of the systems patched properly, especially for WannaCry? Make sure that MS17-017 is installed on ALL of the systems. But also be sure that you haven't been missing other patches as well.
If you still get hits, install Wireshark to track down the source(s) - then go after them.
But if you disconnected all other machines from the network then you may face an outside, wireless or server source.

You should never assume that you're safe when all patches have been installed. 0 day threats will use unpatched vulnerabilities and when they are detected, they are typically detected as heuristic or artemis in your case. Disconnecting devices from the network and trying to located the issue using some sort of network logger (like wireshark) is what I would do. You can use a passive network tap with a known good laptop to gather data.
