The Alternate Data Streams (ADS) allow you to associate some additional information to the files written on a disc with the NTFS filesystem (New Technology System Rows, available with all the Windows operating systems from Windows NT 3.1, therefore including Windows 2000 and XP). Similar in purpose and functionality to the fork used on Macintosh systems, the streams of alternative data concur to save additional information regarding a given file, for example the author and title of a document, or some other information about graphic files. However, the ADS can also contain pieces of malware code and in fact, various malware creators take advantage of this NTFS characteristic to hide their presence on the infected systems. ADS Revealer scans the selected folders or discs, identifying the ADS and giving the user the possibility to export their content and/or remove them.
