When I try to log into Clean Access to use the internet, it gives me an error message saying that in order to fulfill all of my requirements and get into the system, I need to download windows defender. But Windows defender comes with Windows Vista, which is what I have...So when I try to download Windows Defender and install it, it gives me a popup saying that I already have it on my comnputer and that I don't need to download it. Any ideas? Anybody? Please? Am I even in the right place for this kind of question?
