How to disable this security message "Open file security warning"

I found another thread with a user with the same problem and looks like it is a corruption on the permission of the files. Changing the permission of the files should fix the problem.

1-Click on Start, search for Command Prompt

2-Right-click on that and select "Run as Administrator"

3-Paste this command and press Enter:

icacls "c:\Users\zick1\Favorites\*.URL" /t /setintegritylevel m

4-You should see a result like this "Successfully processed files"

5-Then you should be able to access the shortcuts without the warning.

You can see the entire thread at this link.

All SIDs that are prefixed by S-1-15-3 are capability SIDs which are accounts created by apps to grant access to some resources. They are shown as "Account Unknown" because the app was already been uninstalled.

You can see this information in the link below.

"Capability SIDs

Capability security identifiers are used to uniquely and immutably identify capabilities that represent an unforgettable token of authority, which grants access to resources (for example, documents, camera, and location) to Universal Windows Applications. An app that has a capability is granted access to the resource that the capability is associated with, and one that doesn't have a capability is denied access to the resource.

All capability SIDs are prefixed by S-1-15-3."

Check the shortcut properties to see if the files are not blocked.

1-Right-click on one of the shortcuts and click on properties

2-Click on the "General" tab

3-Then check if there is a security warning "This file came from another computer and might blocked to help protect this computer"

4-If have the security warning, check the option "Unblock" then click on Apply and OK to save the change

5-Then check if you can open the file without the security warning. If this procedure works, you will need to repeat for the other shortcuts

Here's a screenshot of the general tab and the security tab. As you can see they don't have the security line you're referring to.

All of the url files I checked had the same verbiage except for the folder location and name. File Explorer recognizes that it is an internet shortcut. Even if I build the url file myself using the "Create Shortcut" it springs the warning and it has the security tab problem spoken of below even though I just created it.

The only thing I don't understand is the "Account Unknown". Each url has the exactly the same thing in the Security tab. I've been unable to find out what that entry is.

Thanks for your reply.

Hi, Fred,

Sorry to hear you're experiencing this issue.

Please provide some more details to help identify what is causing the problem. Does this problem only happen with one specific website? What is the website that you are having a problem with? Did you try to access this website using another browser to check if the same happens in another browser? Do you have any third-party antivirus?

Maybe you should try fix the extension of files first, because it is displayed as Unknown File Type instead as link files.
