# Solution
# from https://forum.antergos.com/topic/818/can-t-run-my-vitualbox/4

pacman -Si linux
sudo pacman -S linux-headers
# will install DKMS properly
sudo pacman -S virtualbox virtualbox-guest-iso

# now this command should work :)
sudo modprobe -a vboxdrv vboxnetflt vboxpci vboxnetadp

# you may run this
sudo /sbin/rcvboxdrv -h

# add current user to vboxusers group
sudo gpasswd -a $USER vboxusers

# now add entries to /etc/modules-load.d/virtualbox.conf
# for startup
vim /etc/modules-load.d/virtualbox.conf
# insert this:
#vboxdrv
#vboxnetadp
#vboxnetflt
#vboxpci

valeu jovem!

I have installed all those packages. My VB still not working.
