What if a file does not have a valid digital signature?

If the file does not have a valid digital signature, there is no way for you to be sure that the file is actually from the source it claims to be from, or that it has not been tampered with (possibly by a virus) since it was published. It's safer to avoid opening the file unless you know for certain who created it and whether the contents are safe to open. Click Related Topics for information about various file types.
