What is NDB file?
The file in the NDB format belongs to the Data Files category. It was designed by Sourcefire. In addition to this file, the Data Files category includes 1326 related files. ClamAV Extended Signature Format is most often found on 3 operating systems. Although it can be found with greater or lesser success on any operating system, it will only be useful on Linux, Mac OS, Windows. This file type can also be opened by 2 other programs. ClamWin, ClamAV will apply when it is not possible to use ClamXav.
How to open NDB file?
The main problem with ClamAV Extended Signature Format is that the NDB file is incorrectly associated with programs. This is manifested by the fact that NDB files open in unusual applications or do not have an assigned program. This problem can be easily remedied.
The first thing you should do is just "doubleclick" on the NDB 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 ClamXav
An often overlooked issue is to make sure that ClamXav is installed on the computer. To do this, enter the name ClamXav into the system search engine. If we do not have this program, it is worth installing it, as it will help you automatically associate the file NDB with ClamXav. Below is a list of programs that support the file NDB.
Programs to open NDB file
Remember to download programs supporting NDB files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of ClamXav with NDB files
If, despite the installed application, the NDB file does not start in the ClamXav application, you must create a file association. It is most convenient to call the context menu with the right mouse button and select Properties. Information about the file and the program that the file is associated with are available here. 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 ClamXav application as the default for handling the NDB file.
Step 3. Update ClamXav to the latest version
If, however, after binding ClamXav with ClamAV Extended Signature Format there were still problems, you should update the program to the latest version.
Step 4. Check for the following problems with the NDB file
The problem may also be with the file itself if the above steps don't work. The most common file problems are:
The NDB file may be unusually small compared to the original file. Usually this applies to NDB 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. Perform a virus scan using available and up-to-date anti-virus software. Some antivirus vendors also provide free online scanners. For the best results, we will scan the entire operating system, not just our NDB file. Sometimes virus-infected NDB 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 NDB files changes over time. These problems are known and are often very easy to fix using the software developers's website.
There can be many reasons for this. The repair method must be adapted to the type of file and damage. Sometimes the program itself has options to repair the most popular NDB file corruption.
The program indicates that the file is encrypted or corrupted. The encrypted file NDB 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. While there is usually no problem reading such a file, it may not be possible to save it. Copying the NDB file to another location will fix the problem.
This problem only occurs with 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. If the error persists after closing other programs, wait for a while. Some anti-virus or backup software may occupy the NDB file for a certain period of time. If the problem persists, restart the machine.
