How to Remove Security Warning Message – Files Downloaded from Internet

How many times, have you seen this dialog when you execute a file which was downloaded from Internet?  For example, this Process Explorer message box below. This would come-up, every-time you run this executable. Also, when you open any of the help file from the downloaded suite you see this ‘Navigation Cancelled’ dialog.

Issues because of the Security Zone Information

The problem is that, when you download any of the files from the internet, using internet explorer, it gets tagged with metadata in alternate data stream, and says what IE Security zone did it came from. and even though, when you are running it from the local file system, windows remembers that it came from the internet.

Methods to resolve this –

1. Easiest way is to remove the zone information using the file Properties. Before you extract the zip file, Right-click on the file, select Properties tab. Click on the un-block button to remove the alternate data stream – Security zone information.

2. The other option, is to use a Sysinternals tool called Streams. Streams will examine the files and directories you specify and inform you of the name and sizes of any named streams it encounters within those files. Streams makes use of an undocumented native function for retrieving file stream information.

Using this parameter, streams -d will remove the Zone identifier information from a file and you will not see the security warning message/dialog.
