AVG said consent exe was a virus and removed it now I can't run anything including restoring consent exe what do I do?"

The file was in the virus vault, unfortunately without consent.exe active you don't have permission to restore it.  I have finally resolved this, and I will record this for others who may share a similar fate.   You are completely unable to run anything in Windows, or on the cmd prompt, without first putting it in /SAFE mode.  Anyway, first, I looked at a previous version of the c:\windows\system32 folder (folder, properties, previous versions).  I copied the file content.exe to a USB stick, I couldn't copy it to the correct folder, without permission.  I then rebooted my machine into safe mode with a command prompt, which gave me administrator rights, and brought back some memories (I am that old) remembering how to use DOS copy;
copy e:\content.exe  c:\windows\system32\content.exe
Rebooted and everything worked again.  Sounds, easy, but it took me some time of experimenting with other methods, and a nod to someone on a tech forum, who gave me the idea from something they had dealt with.  AVG has not shouted about the file again, so no idea why it did the first time, but I will be checking suggestions to protect more thoroughly in future.

I was unable to enter cmd prompt from advanced options, and could not access safe mode (comp would spin in endless wait mode and only boot to windows 10 with my restrictions enforced).
Finally, however, I was able (after shift +restart under advanced options, clicking something about restore to previous state or last version) it began to offer entrance to bios menus.  It did hang as it attempted to restore itself to the previous state, so much so I shut it down as I had found before it seemed to be in an infinite loop.  However, it did restore itself enough that the file, consent.exe, was reinstated and system control with full privileges were returned to me.
Had it not, I know I would have been able to access cmd function from safe mode and installed the file manually.
Thank you all for this thread.  I was very nearly at my wits end.
