I have had a brain fart, and need someone to remind me how to allow a program to run, without having to tell UAC to allow it every time. I did it, one time but now that I have reinstalled, I just can't remember. When I find out, I will go DUH!!!
Any program that is not a microsoft program, evokes the dreaded "Do you want to allow this program access to your computer?". It's not that I am having trouble, I am just tired of having allow every single program every time. Yet if you turn off UAC then there are some more indepth things that you can not do without turning it back on. (It's been a while, I don't remember exactly what). I guess it's a trade-off.
I believe that is coming from Windows Defender. I have always had it disabled in Servces , but a user can pop in here and tell you how to stop that message, which is certainly possible. You could also open it from the Control Panel and habve a go yourself. I think you will find it under "Options"
