Cannot remove vmbr0 in the interface configuration

[decibel83]

Hi.
In my interfaces configuration I have the vmbr0 interface, not setted up and not active, and without any bridge ports. If I try to remove it does not remove from the interface, and if I check in /etc/network/interfaces or /etc/network/interfaces.new there aren't any reference about the vmbr0 interface. "ifconfig vmbr0" returns that the interface does not exist, of course, and I cannot recreate it because the inteface tells me that it already exists...

How I can solve this removing and recreating the interface?

Thank you very much!
Bye.

The interfaces still does not let me to remove the vmbr0 interface.
