Thanks for the professional response. Symptoms are too detailed and copious to explain, in this fashion anyhow. I'll do my best in an effort to be succinct: Quickly reoccurring ( over the last couple years) malware per several AV'S after the Genius Bar folks and eventually some pretty high level Apple employed Techs went through every re - imaging, re - flashing firmware " technique" possible. Apple has tried very hard to properly erase and install ( at the deepest level possible) new operating systems. Unfortunately, on all of our devices we pick up malware very quickly. We've been told they are root kitted and that's one explanation as to why they were being operated without a network connection AT ALL!! I must admit that part ( system certs being created via a hidden guest user account ) has been fixed. Although, many more, constant and hard to believe let's call " activities" for lack of a better word still seem to be a question mark. This is not just my opinion. We've paid technologists to analyze but it got far to expensive. I'm not software savvy and don't pretend to be. I'm here to look for advise and help.
The most recent professional opinion is "it's very possibly in the firmware or bios or some customized malware is somewhere else on the LAN and it's just continued to reinfect.
I've had to take our computers in for re- image and/or hard drive replacement so many times that some of the Apple employees have said, " we've never seen anything like this"
Whatever the above describes or sounds like is.... from my non- technical, non computer professional, opinion sounds very similar to some type of EFI, boot process, firmware/malware.
Who knows, It appears our best option is to simply replace all of the hardware.
Since this is not a previously popular topic I'm happy to place it elsewhere if that's the best path.
Thanks All!
