Mar 11, 2018 - How to Disable “Open File – Security Warning” in Windows 7. Computers, users sometimes download programs without much consideration. The Open File - Security Warning prompt is a security measure in Windows 7 and Vista to ask for your permission (like UAC) before allowing a downloaded or copied file from the internet or another computer to be opened or run on your computer. In this case, the 'Temporary Internet Files' folder has insufficient permissions in its new location. Therefore, the Phishing Filter cannot start. When this problem occurs, Internet Explorer 7 cannot start, and the File Download – Security Warning dialog box opens.


How to Unblock a File in Windows 10
The Attachment Manager is included in Windows to help protect your PC from unsafe attachments that you might receive with an e-mail message and from unsafe files that you might save from the Internet. If the Attachment Manager identifies an attachment that might be unsafe, the Attachment Manager prevents (blocks) you from opening the file, or it warns you before you open the file.
It uses the IAttachmentExecute application programming interface (API) to find the file type, to find the file association. When one of these applications saves a downloaded file on a disk formatted with NTFS, then it updates the metadata for the file with the zone it was downloaded from. The metadata is saved as an Alternate Data Stream (ADS). If you wish to unblock a downloaded file, you can do so by right-clicking it, selecting Properties and clicking on Unblock.
The following determine whether you are prevented from opening the file or whether you are warned before you open the file:Security
  • The type of program that you are using.
  • The file type that you are downloading or trying to open
  • The security settings of the Web content zone that you are downloading the file from.
    • Internet
    • Local intranet
    • Trusted sites
    • Restricted sites

The Attachment Manager classifies files that you receive or that you download based on the file type and the file name extension. Attachment Manager classifies files types as high risk, medium risk, and low risk.
  • High Risk – If the attachment is in the list of high risk file types and is from the restricted zone, Windows blocks the user from accessing the file. If the file is from the Internet zone, Windows prompts the user with a Windows Security Warning: Windows found that this file is potentially harmful. To help protect your computer, Windows has blocked access to this file.
  • Moderate Risk – If the attachment is in the list of moderate risk file types and is from the restricted or Internet zone, Windows prompts the user with a warning: 'The publisher could not be verified. Are you sure you want to run this software?'.
  • Low Risk – If the attachment is in the list of low risk file types, Windows will not prompt the user before accessing the file, regardless of the file’s zone information.

The Open File - Security Warning prompt is a security measure that will ask for your permission before opening a file on your PC that came from an unknown source such as the Internet or another PC.
Windows SmartScreen helps keep your PC safer by warning you before running unrecognized apps and files downloaded from the Internet.
Open File - Security Warning and Windows SmartScreen automatically blocks these types of apps and files until you unblock them.
Starting with Windows 10 build 17639, if you have Windows Defender Application Guard turned on, blocked files will have a icon overlay on the file's icon to indicate the file is currently blocked.
This tutorial will show you different ways on how to unblock files that are blocked by Open File - Security Warning and Windows SmartScreen in Windows 10.

Problems with browsers are not unusual. But this one has been caused by a security update released by Microsoft recently for Widows 10, Windows 8.1 and Windows 7 OS. There is this strange behavior of the File Download Security Warning box opening when you try to open URL files saved in the Favorites folder. This problem was recently noticed in all the browser.

Scores of Windows users recently complained about a strange browser behavior they witnessed while running their default browser in Windows 10. The problem was not specific to Windows 10 as systems running an older version of Windows like Windows 7 and Windows 8.1 too were affected by it.

A Windows 10 user posted on Answers:

When I open a folder or file window and click to “Favorites” folder, then double-click to open a .url file I get a Windows warning popup “File Download – security warning”, “Do you want to open this file?”. This has been happening since the September 13, 2016, second Tuesday windows update. This did not happen before September 13, 2016, second Tuesday windows update.

Clicking on Favorites opens the File Download Security Warning box

Users started experiencing this issue after they installed the security patch KB3185319 for Internet Explorer. If you uninstall this update, the issue will go away.

But a workaround has been suggested that will help you fix the issue. Here’s what you can do.

If you are using computer as a normal user account, open an Administrator command prompt and type in the following commands one after the other and hit Enter:

Once you run these commands, the issue is likely to get resolved.

Please note that you will have to give the appropriate path to your Internet Explorer favorites for the first command. Also, this fix works only for the current items saved in the “Favorites” folder. The above steps have to be repeated every time you add a new favorite.

It is a pity that every new update brings some problem or the other to the Windows user. The percentage who face issues may be minuscule or small – but this just shouldn’t be happening, in my opinion.
