How to open ARU file?

The most common problem when using Autorun.aru Malicious is that a specific ARU is not associated with the program. This is manifested by the fact that ARU files open in unusual applications or do not have an assigned program. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the ARU 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

The first step is to check if the computer has the avast! Antivirus program installed. The easiest method is to use the system search engine by entering the program name avast! Antivirus in it. If we do not have this program, it is worth installing it, as it will help you automatically associate the file ARU with avast! Antivirus. Below is a list of programs that support the file ARU.

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

However, it may happen that the application itself does not cause the ARU file to open in the avast! Antivirus application, but you can set it manually. 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. Changes can be made using the "Change" button. 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. The "always use the selected program ..." field will set the avast! Antivirus application as the default for handling the ARU file.

Step 3. Update avast! Antivirus to the latest version

If, despite the association of the avast! Antivirus program with the Autorun.aru Malicious file, the file still does not open, check the program version and possibly update it to the newest 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 ARU 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 affected file may be 0 KB or smaller than expected. Usually this applies to ARU files downloaded from the Internet in case the download did not finish properly. 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. However, it is important to scan the entire system, not only the file ARU or the program directory. However, remember that not every infected ARU file can be recovered, so it is important to take care of regular backups.
A typical compatibility error - the program does not support the older version of the ARU file. 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. The repair method must be adapted to the type of file and damage. Some programs offer the ability to automatically repair ARU file corruption. You can restore the file from a backup or use N/A help.
The program can also signal the fact of encryption. The encrypted file ARU 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. Copying the ARU file to another location will fix the problem.
This problem usually affects more complex files. Some file types can only be opened in one program at a time. Running programs (including those in the background) should be verified. Sometimes you have to wait for the session to the file ARU to close. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If the problem persists, restart the machine.
