So a few days ago I deleted a program from my computer, which I didn't need anymore. From that moment, my Firefox didn't want to browse the internet anymore. when I want to navigate to a page, nothing happens. Most other programs like iTunes ,Steam and Google Chrome can't connect to the internet either. For some reason Internet Explorer still manages to connect to the internet. I'm not a real expert as regards software but I think that when I deleted the aforementioned program, it deleted a windows file as well which is essential to connect to the internet. Is that possible? Anyways, I hope that someone can help me out with this. Thanks in advance!
