Tony Anceriz perhaps said it best in his Support Post:
AVG TuneUp Destroyed My Registry!
WTF?!? If AVG is aware of this problem, why isn't the workaround published?Is AVG still wanting to stay in business? Does AVG care about it's customers?
I can't figure out why this disastrous release was made available, and even more so why AVG hasn't owned up to it and fixed it already!!!
