How to open NPFX file?
An often recurring problem with Norton Internet Security Firewall Settings Format is that NPFX is not associated with the correct program file.

The first thing you should do is just "doubleclick" on the NPFX file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.
Step 1. Install Norton Internet Security

Programs to open NPFX file
Remember to download programs supporting NPFX files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of Norton Internet Security with NPFX files
If the application is or has been freshly installed, but the NPFX file still does not use the Norton Internet Security program, it means no association. This option is available from the level of Properties of a specific file available in the context menu. The window will show, among other things, the type of the file and the information by which the program is used to launch the file. Using the "Change" button we can set the program to handle this type. The program should be visible in the window, otherwise it should be selected manually using the "Browse" button and the program installation directory should be indicated. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the NPFX file with the Norton Internet Security application.
Step 3. Update Norton Internet Security to the latest version
The fault may also lie with the Norton Internet Security program, it is possible that Norton Internet Security Firewall Settings Format requires a newer version of the program. Some applications allow you to update from the program level, and for others you need to download the installer from the Symantec Corporation page and install.
Step 4. Check for the following problems with the NPFX file
The problem may also be with the file itself if the above steps don't work. This could be due to the file itself, the cleanest issues are:
The NPFX file may be unusually small compared to the original file. This is most often caused by a problem while downloading the NPFX file. The only repair option is to download the file again.
The operating system may be infected with a computer virus. A virus scan using an up-to-date antivirus program should fix the problem. Alternatively, you can use the scanners available online. However, it is important to scan the entire system, not only the file NPFX or the program directory. Sometimes virus-infected NPFX files cannot be recovered, so make a backup in advance.
This can happen especially when the program is dynamically developed and the structure of the NPFX files changes over time. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
There can be many reasons for the failure. Depending on the type of file, it is necessary to repair it accordingly. Sometimes the program itself has options to repair the most popular NPFX file corruption. The easiest way to restore the file is from a backup or by contacting Symantec, but this one can be expensive. Not all damage can be reversed.
When reading, a message appears that the file was encrypted or corrupted. The encrypted NPFX files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
Some of the system directories are excluded from modification. While there is usually no problem reading such a file, it may not be possible to save it. If possible, you can try to move the NPFX file to another location.
This problem usually affects more complex files. You may find that another program you are using is preventing you from working with the file. Running programs (including those in the background) should be verified. If the error persists after closing other programs, wait for a while. However, some background programs may block the NPFX file while scanning. If the problem persists, restart the machine.
