SE disappeared about a week ago after trying to fix iTunes problem or when I got the newest Adobe. Can neither install nor uninstall SE- says it's on a network resource that's unavailable - I do not have a network setup. So I thought I'd get Defender to have at least some protection but it won't let me install: says remove client protection... have no idea what they are talking about... I see now that Defender is less valuable than SE - but heck, I need protection for my system. How can I get Defender installed?

I'm not sure what you mean by SE. If you mean Microsoft Security Essentials, I recommend posting your question in the Microsoft Security Essentials: Getting Started and Upgrading forum.Boulder Computer Maven Microsoft Most Valuable Professional

Windows Defender is Anti-Spyware while MSE is Anti-Spyware+Anti-Malware.I suggest to contact MSE support for more help:https://support.microsoftsecurityessentials.com/
