Okay I tried uninstalling mabinogi and gameguard. It failed to uninstall gameguard from my system. I tried deleting the the whole nexon folder and my computer says it's being accessed thus cannot be removed. This is VERY annoying and is akin to installing a spyware/trojan on my computer.
Edit: I finally figured out how to remove gameguard and have to manually remove it.. very annoying piece of shit software *shake head*.
