 Virus Protection We use virus protection software on our computer systems and regularly update the software. This is a computer security measure that, in addition to maintaining our computer systems, also ensures that all files that we develop and/or post on our web servers are virus-free. When you request a file for download from our site, it is possible, though unlikely, that the data may contract a virus and become corrupted before it reaches your computer. The National Archives and Records Administration is not responsible for files that may become corrupted as the data travels the Internet.
