I download Firefox and can't install it. Get a "Not valid Win32 application." I get this with any program I want to install. I suspect a virus.

No program that has not been installed will linstall. No matter which I try, I always get "Not a valid Win32 application." I also clicked the "Automatic troubleshooting information," below, and it never stopped downloading so I was not able to go any further. It seems Windows must be fixed, somehow, but I have no idea about that. I tried to install both AVG and Avast anti-virus but it seems to be too late. Whatever I have prevents either of them from installing, too. 

    Nothing ever popped up, including a window with Allow. As the alternative, I don't see a Help>Troubleshooting Information, either.

Get firefox from getfirefox.com then try again. Or from here (both link to same page) https://www.mozilla.org/en-US/firefox/new/

If it says not a valid Win32 app it is likely the download is corrupted, messed up etc.

This happens with ANY program I want to install. I downloaded Firefox from the same site when I had the first experience. I tried it again from the suggested sites and got the same pop-up. It seems that something is preventing all program installations. Unfortunaely, this extends to anti-virus programs, as well. That is my dilemma.

Can you run programs already installed, if so TDSSKiller, Hitman Pro, ESET Online will work as they are not required to be installed.

And if that isn't even possible use another computer to burn this onto a CD.
