AVG will not close in my task manager

I did that already. I actually did a full uninstall of AVG then reinstalled it and repaired it after reinstalling it. It's still there, just beyond the pale. Mocking me, tormenting me with its presence. It's more of an annoyance than a hinderance really. 

The trouble starts when I actually open AVG. If it isn't opened there is no issue. But, once it is opened and the avgui.exe has been activated, it stays open until I either restart or shut down my PC. I've tried clicking on it and choosing End Task, that doesn't work. The uninstall didn't do anything, I even deleted all the remaining files after uninstalling to get a clean slate. It's always there though. In my Task Manager it has a dropdown menu from AVG User Interface. The dropdown menu displays a blank program that consistently takes up around 6mb. It doesn't do much else, but it stays there until, like I said, my computer is either retarted or shut down completely. 

it's probably that then. One question; why does it show up as a blank process? It doesn't have a name nor does it allow me to close it via End Task.
