Thanks for the clarification, but...
I did download it to the desktop and attempt to run it. After my last post, I renamed the file to OTH.exe, right clicked the file and selected Run as Administrator. The application launched and I clicked "Kill All Processes" as directed. Nothing appeared to happen. Specifically the desktop did not go black. After about a half hour, I tried to take the next step and run dds.exe from the OTH console as directed.
When I clicked the button and got the window to browse for files, it was empty. No matter what directory I pointed it at, no files or subdirectories were visible. I ended up pointing it at the Desktop directory and entering the file name "dds.exe" and clicking the "Open" button. DDS launched, but acted exactly as before.
I am now running aswMBR. It asked to download Avast definitions which I accepted. It is downloading now and I will post the results in my next reply.
