Does that line inform you of any message(s) that may harm you. Well according to Microsoft it should, which would imply that "The file has been scanned for viruses. We don't know if it actually contains virus. Download and open at your own risk. You've been warned."
I don't know if they have realized or not, but they have placed a warning icon next to above information. Technically it is incorrect and misrepresented, unless MS has altered its meaning.
