Programs to open KLZ file

Remember to download programs supporting KLZ files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of Kaspersky Anti-Virus with KLZ files

If the application is or has been freshly installed, but the KLZ file still does not use the Kaspersky Anti-Virus 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. The "always use the selected program ..." field will set the Kaspersky Anti-Virus application as the default for handling the KLZ file.

Step 3. Update Kaspersky Anti-Virus to the latest version

If, however, after binding Kaspersky Anti-Virus with Kaspersky Anti-Virus Update Format there were still problems, you should update the program to the latest version. In this case, use the Kaspersky Lab website or update the program from the application.

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

If the above steps do not help, you can assume that the file itself is not correct. The most common file problems are:

The KLZ file may be unusually small compared to the original file. Usually this applies to KLZ files downloaded from the Internet in case the download did not finish properly. The only repair option is to download the file again.
The computer may have fallen victim to a computer virus or hacker. A virus scan using an up-to-date antivirus program should fix the problem. Alternatively, you can use the scanners available online. For the best results, we will scan the entire operating system, not just our KLZ file. However, remember that not every infected KLZ file can be recovered, so it is important to take care of regular backups.
This can happen especially when the program is dynamically developed and the structure of the KLZ 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 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 KLZ file corruption. You can restore the file from a backup or use help.
The program indicates that the file is encrypted or corrupted. The encrypted KLZ 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.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. These directories are write-protected to them and it's very hard to fix this problem. If possible, you can try to move the KLZ file to another location.
This can happen on a file that does not support multiple access. You may find that another program you are using is preventing you from working with the file. Closing other programs should help. Sometimes you have to wait for the session to the file KLZ 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.
