I installed VirtualBox when I was running Ubuntu GNOME 15.10 with GNOME 3.18 from the official repository (details are given on the official site), however when I upgraded to Ubuntu GNOME 16.04 with GNOME 3.20 I found that the new kernel did not allow unsigned kernel modules and as Oracle doesn't sign them (or at least didn't back then, I don't know about now) they can't be run. So I purged it using apt-get (or maybe I used remove, but I don't remember).

But now I am concerned that it has left something behind for when I run the networkctl this is the output:

IDX LINK             TYPE               OPERATIONAL SETUP     
  1 lo               loopback           n/a         n/a       
  2 enp3s0           ether              n/a         n/a       
  3 wlp2s0b1         wlan               n/a         n/a       
  4 virbr0           ether              n/a         n/a       
  5 virbr0-nic       ether              n/a         n/a

And here is part of the output from ifconfig:

virbr0    Link encap:Ethernet  HWaddr 00:00:00:00:00:00  
          inet addr:192.168.122.1  Bcast:192.168.122.255  Mask:255.255.255.0
          UP BROADCAST MULTICAST  MTU:1500  Metric:1

          collisions:0 txqueuelen:1000 
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

It seems to be named similar to the VirtualBox standard, so is this something left behind from VirtualBox or something else? If it is from VirtualBox then can I safely and cleanly remove it and will there be anything else left in my system? Also, could it cause me any harm if it just stays there as it is?
