What is the avqmd.plist and the _avqmd record in Users/Groups Today, I was trying to fix the file permissions and ownership on an external hard drive and while I was trying to add myself as a user/owner the through the get Info window, the system presented me with an unknown to me user with the name: _avqmd.

Of course there is no indication for such user in the system preferences -> users.

But I was also able to spot a avqmd.plist file inside: /var/db/dslocal/nodes/Default/users 

Does anyone know what is this and from where it comes from?
You might be able to get some more details on the user by querying your directory database rather than looking at the record files on the filesystem:

dscl . -read /Users/_avqmd


Hopefully you'll find enough threads to pull on. It's not an account on any of the first few Macs I checked, but perhaps someone else has tracked it down already and has a more concrete answer.
