Both the EB link as also the Unlocker link come from their creators which I doubt strongly send virusses around the world!
Start your OS in safe mode and delete the files you argue with.
And why doesn't Unlocker work? Did you double-click on the icon in the task bar?

Another issue I see from here is your browser setting, disable the automatic opening of downloaded files, it seems as if FF an IE have a process running on your files.
