How to open FNR file?

An often recurring problem with Trojan-Dropper.Win32.Flystud.lc. is that FNR is not associated with the correct program file. This is manifested by the fact that FNR files open in unusual applications or do not have an assigned program. How to solve such a problem?

The first thing you should do is just "doubleclick" on the FNR 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 avast! Antivirus

In this case, you should first verify that the avast! Antivirus application is installed on the computer. This can be achieved by typing avast! Antivirus into the operating system search engine. If we do not have this program, it is worth installing it, as it will help you automatically associate the file FNR with avast! Antivirus. Later in this article you will find a list of programs that can open FNR files.

Step 2. Create association of avast! Antivirus with FNR files

If, despite the installed application, the FNR file does not start in the avast! Antivirus application, you must create a file association. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. Information about the file and the program that the file is associated with are available here. Using the "Change" button we can select the desired program. 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. Checking the "Always use the selected program ..." box will permanently associate the FNR file with the avast! Antivirus program.

Step 3. Update avast! Antivirus to the latest version

If, however, after binding avast! Antivirus with Trojan-Dropper.Win32.Flystud.lc. there were still problems, you should update the program to the latest version. This can be done using the application (if it provides such options) or from the AVAST Software a.s. website and install the latest version.

Step 4. Check for the following problems with the FNR file

If the above steps do not help, you can assume that the file itself is not correct. This could be due to the file itself, the cleanest issues are:

The FNR file may be unusually small compared to the original file. This is most often caused by a problem while downloading the FNR file. The only repair option is to download the file again.
The most common cause here is computer viruses. A virus scan using an up-to-date antivirus program should fix the problem. If this is not possible, you can use the online scanner. For the best results, we will scan the entire operating system, not just our FNR file. Sometimes virus-infected FNR 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 FNR files changes over time. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
The file may be corrupted in a number of ways. The repair method must be adapted to the type of file and damage. Sometimes the program itself has options to repair the most popular FNR file corruption. The easiest way to restore the file is from a backup or by contacting N/A, 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 FNR files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. The problem is only writing to the file, not reading it. It is best to move FNR to a different directory.
This problem only occurs with more complex files. You may find that another program you are using is preventing you from working with the file. Closing other programs should help. If the error persists after closing other programs, wait for a while. Some anti-virus or backup software may occupy the FNR file for a certain period of time. If nothing helps, please reset the device.
