Ads Spy is a tool used to list, view or delete Alternate Data Streams (ADS) on Windows 2000/XP with NTFS file systems. ADS is a way of storing meta-information for files without actually storing the information in the file it belongs to, carried over from early MacOS compatibility from Windows NT4. Recently browser hijackers began using this technique to store hidden information on the system, and even store trojan executable files in ADS streams of random files on the system. Use with caution.
Usage Instructions:
Download this program and run it. If you would like to just scan the Windows directory, then you can click on the Scan System button and it will scan your Windows directory for Alternate Data Stream files. You then have the option to select the ones you would like to delete, and press the Remove button. If you would like to scan the entire hard drive for ADS files, uncheck the Quick Check checkbox.
