On Windows, Attachment Manager's job is to protect you from downloads that may not be safe for your system. The administrator performs this task by identifying the file type and related security settings. Based on the security information provided by the zone information, Windows uses Attachment Manager to warn you before opening the file or often to block access to these potentially harmful files. While this is a really good security measure provided by Microsoft, the problem is that Windows sometimes classifies a trusted source as malicious, if the file is from an email attachment, if you downloaded it from the Internet; These files are major suspects of being blocked by Windows for your protection.

When Windows blocks access to a file, you will get a message like this when you try to open it: “Windows has discovered this file is potentially harmful. To protect your computer, Windows has blocked access to this file. “Only one option is provided under this notice:” OK “and once selected, you are shown an empty folder. But of course, you really need that locked file, is there any way to access it?

Of course, there is a simple solution to this problem, but before you go ahead and unlock the file for access, make sure it is a safe file and that it has no chance of infecting your computer with a virus or malware. If you're still unsure, you can scan the file (you won't have to open the file for that). If you wish to continue without scanning, do so at your own risk.

In case Windows does not block a file but considers it potentially harmful, it will display security warnings every time the file is opened. It will say “Could not verify publisher. Are you sure you want to run this software? “Getting this warning is better than having to unlock a file, but it can be quite irritating to face the warning and click Run every time you want to access the file.

  • All you need to do to make sure the warning never appears again is to simply uncheck the checkbox that says “Always ask before opening this file”. Windows will never show the warning for this file again.
  • However, it may display warnings for other files and you will need to uncheck the “Always ask before opening this file” box individually for each one.

  • Click the Start button and right-click Computer.
  • Choose Properties from the options displayed.
