I think that Forge has paired up with some company and done some pretty annoying stuff.
As I was getting forge for Minecraft, and I went through the installer, I found a odd number of terms of services.
So as it was downloading, I found my computer moved the entire screen down, and some app I never wanted appeared on the top.
Luckily, I know about Task Manager, and I stopped it.
Anyway, my suggestion is to get a better installer and make it so you don't give away apps people never wanted to get.
