norton update 22.5 causing issues on our Point of Sale host, it is blocking services we need and trust

Our Norton Antivirus was updated from 21.7.0.11 to 22.5.0.124.  no one admits they updated it - we did not want to update - maybe it auto-updates? anyway, after updating, we are having LOTS of trouble.  it seems to quarantine a ton of files - most of them part of our actual POS (micros) program or other trusted programs.  I added the entire D:\Micros directory to the ignore list.  then it seemed to stop our in-house app from communicating, and it turned out something had stopped the service that runs the app in services.msc.  coincidence, or can Norton stop a service?  I had previously placed C:\relevant and C:\program files (86)\relevant in the ignore category, but Norton still seems to have stopped the service.  we have 22 locations.  2 accidentally updated Norton and 20 did not.  no problems at the 20, TONS of problems at the 2 with updates.  I will try the suggested solution for the known issue with quarantine and Cloud.9 detection.  I guess my biggest question is "can this version of Norton stop a service, and if so, how do I prevent that behavior?"  and is there any way to return to 21.7.0.11?
