Ever been setting up or managing a system and run into a
prompt like this:
It’s probably because you grabbed the original executable
from an Internet site.
Using a modern browser to grab the file will typically result in a special NTFS stream added to the originally-downloaded file
(eg, bginfo.zip) that gets promulgated to the executable you’re trying to run.
This can be a good thing when you're trying out software, but how do you fix it when you know you can trust the file? This sort of thing can be come quite annoying if it's tied to a Startup item like BGInfo.
The best solution is to “unblock” the file you download;
that keeps the stream from being added to the extracted file(s). But what if
you’ve already extracted them?
Same solution, but you apply it to the executable instead of
the download. Right-click on the file to unblock, then select properties. You
should see something a bit like this:
Note the [Unblock] button at the bottom. If you click that
and save the properties, the NTFS stream metadata is removed from the file, and
you won’t get the popup message whenever the app is run.
When I'm retrieving trusted files from my own web servers, I’ve simply gotten
into the habit of unblocking files as soon as I download them; if the ZIP or
installer file doesn’t have that metadata, the extracted files won’t inherit
them.
Also: there’s no way to mass-unblock files; if you select a group of
files and choose properties, you don’t get the option to edit the security. If you're downloading a zip file full of executables (like the SysInternals Suite), you definitely want to unblock the ZIP file before extracting it, or you'll have to unblock each executable individually.
Inside that SysInternals suite is a utility called streams.exe. Wrap it up in a batch file, and you can run it on your download directory to fix all the files at once.
