7-zip has finally added support for the long-requested ‘Mark-of-the-Web’ Windows security feature, providing better protection from malicious downloaded files. When you download documents and executables from the web, Windows adds a special ‘Zone.Id’ alternate data stream to the file called the Mark-of-the-Web (MoTW). This identifier tells Windows and supported applications that the file was downloaded from another computer or the Internet and, therefore, could be a risk to open.
