Your Internet security settings prevented one or more files in Windows 11

Published by Nyau Wai Hoe - Updated on

If you receive a warning message that says “These files can’t be opened – Your Internet security prevented one or more files from being opened” whenever you try to run an executable file (.exe file) in Windows 11, especially for installer files downloaded from the Internet, this guide will show you how to resolve the issue.

When the warning prompt appears, you will only have the “Close” button to click and the executable file will not be run. The warning message indicates that Windows Security has blocked the file from being opened due to the Internet security settings.

This problem usually occurs when the downloaded executable file does not have a valid certificate or is flagged as suspicious, causing the file to be blocked by Windows Security and prompt the user the “Your Internet security settings prevented one or more files” warning message.

Temporary disable firewall and antivirus program (not recommended)

Since it’s a security issue, you might want to try disabling your firewall and antivirus program before running the exe file. Alternatively, you can allow only the exe file through your firewall and add the file to the exclusion list in your antivirus software, if you don’t want to disable them.

You should ONLY do this if you fully trust the source of the executable file. Disabling firewall or antivirus shield may put your PC at risk of being infected by malware or viruses if the file you run is in fact malicious.

Also, if you do try to disable any of the firewall, antivirus or other security software or program, be sure to re-enable them right after you’ve done what’s needed.

Use another user account or create a new one

Another method would be to try using another user account in the same Windows to open the executable file. If you do not have a secondary account, you can create a new one by following the steps in this post: How to Create Local Admin Account Without Password on Windows 11.
