How to open DELF file?

An often recurring problem with Malicious Or Virus is that DELF is not associated with the correct program file. This causes the file DELF to open by system applications not designed for this purpose, or to display a message that there is no associated program. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the DELF 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 Avira AntiVir Personal

An often overlooked issue is to make sure that Avira AntiVir Personal is installed on the computer. This can be achieved by typing Avira AntiVir Personal 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 DELF with Avira AntiVir Personal. Later in this article you will find a list of programs that can open DELF files.

Step 2. Create association of Avira AntiVir Personal with DELF files

If the application is or has been freshly installed, but the DELF file still does not use the Avira AntiVir Personal program, it means no association. This option is available from the level of Properties of a specific file available in the context menu. Information about the file and the program that the file is associated with are available here. Changes can be made using the "Change" button. It may happen that in the next window there will be no appropriate program - however, this can be corrected with the "Browse" option where you should manually indicate the program location. The "always use the selected program ..." field will set the Avira AntiVir Personal application as the default for handling the DELF file.

Step 3. Update Avira AntiVir Personal to the latest version

The fault may also lie with the Avira AntiVir Personal program, it is possible that Malicious Or Virus requires a newer version of the program.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 Avira GmbH page and install.

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

Of course, it may happen that despite the above steps, the file still does not work. This could be due to the file itself, the cleanest issues are:

The DELF file may be unusually small compared to the original file. This is most often caused by a problem while downloading the DELF 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. Some antivirus vendors also provide free online scanners. For the best results, we will scan the entire operating system, not just our DELF file. Sometimes virus-infected DELF 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 DELF 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 this. Depending on the type of file, it is necessary to repair it accordingly. Sometimes the program itself has options to repair the most popular DELF file corruption. The easiest way is to restore the file from a backup, if there is one, or contact N/A
The program indicates that the file is encrypted or corrupted. The encrypted file DELF except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. The problem is only writing to the file, not reading it. It is best to move DELF to a different directory.
This can happen on a file that does not support multiple access. In this case, the DELF file is blocked by the first application to open it. Just close unnecessary programs. If the error persists after closing other programs, wait for a while. Some anti-virus or backup software may occupy the DELF file for a certain period of time. If nothing helps, please reset the device.
