Air won't download

From the Adobe download page, I click "install" the screen flickers and send me right back to the install page where I started. Like an idiot I uninstalled Air to see if that would allow the download... it didn't now I have no Air installed and can't download a new install. I'm on an Intel Mac. The error message says I have to disable virus protectio, only I don't have any.

I have tried to download the run version from 3 different places and the same thing happens... the download won't install, always flips me right back to the start screen.

I run a lot of important apps on Air and now I am down.

Any help would be Greatly appreciated.
