ZoneIDTrimmer helps to detect and remove an alternative data stream
(Zone.Identifier) stored by Windows in files downloaded from the Internet or
email attachments saved on your disk, causing a security warning when these
files are used. After installing this software affected files and folders
containing such files will be marked in Windows Explorer with an exclamation
sign and "Trim Zone ID" command will be added to the context (right click)
menu. (in System Utilities)
