When I download EtreCheck - I could not open the app.
It's just an app like any other. Nothing special about it. If you can't run apps, maybe erase the hard drive and reinstall the operating system. When you restore from backup, restore only your user files and user documents. Do not restore any apps, software, system settings, or "other apps". You can manually reinstall only the apps that you really need.
As a side benefit, doing this will definitively resolve whatever problem you had downloaded EtreCheck to try to help solve. You would then be able to ignore everything else below.
Next, I went to System Settings and in Security I selected "allow" for the app.
You would only need to do this if you had changed your default setting to only run apps from the Mac App Store. Judging from your previous question, it's a little late to lock the doors of your software barn after you've filled it up with malware. Now you're just blocking the legitimate, helpful apps.
The default settings are very safe and secure. You had to manually bypass multiple layers of Apple security protections to have downloaded and installed all of that malware to begin with.
After downloading the excutable files I receive the following two messages.
I did not go into Terminal mode. I remained in the Normal mode.
You're literally running the Terminal there. I don't know why you are running the Terminal at all. I definitely don't know why you are trying to run EtreCheck in the Terminal. Trying to run EtreCheck's StorageHelper in the Terminal is definitely not going to work out for you in any way.
It looks like maybe you are digging into the app bundle and manually double-clicking on files? I strongly recommend that you don't do that.
