The CAV file is supported on 1 operating systems. Depending on your operating system, you may need different software to handle the CAV files. Below is a summary of the number of programs that support and open the CAV file on each system platform.
What is CAV file?
The file in the CAV format belongs to the Data Files category. It was designed by Comodo Group. Additionally, the Data Files category contains 1326 of other files. Comodo Virus Definitions Format appears on 1 operating systems as a functional file. The file will work on Windows systems, unfortunately not on others. It is recommended to use Comodo Internet Security to handle this file. This is a program created by Comodo Group, Inc..
How to open CAV file?
The most common problem when using Comodo Virus Definitions Format is that a specific CAV is not associated with the program. This causes the file CAV to open by system applications not designed for this purpose, or to display a message that there is no associated program. How to solve such a problem?
The first thing you should do is just "doubleclick" on the CAV 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 Comodo Internet Security
The first step is to check if the computer has the Comodo Internet Security program installed. This can be achieved by typing Comodo Internet Security into the operating system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Later in this article you will find a list of programs that can open CAV files.
Programs to open CAV file
Remember to download programs supporting CAV files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of Comodo Internet Security with CAV files
If the application is or has been freshly installed, but the CAV file still does not use the Comodo Internet Security program, it means no association. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. The displayed window will contain information about the program that supports this type of file. Using the "Change" button we can select the desired program. 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. Checking the "Always use the selected program ..." box will permanently associate the CAV file with the Comodo Internet Security program.
Step 3. Update Comodo Internet Security to the latest version
The fault may also lie with the Comodo Internet Security program, it is possible that Comodo Virus Definitions Format requires a newer version of the program. This can be done using the application (if it provides such options) or from the Comodo Group, Inc. website and install the latest version.
Step 4. Check for the following problems with the CAV 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 CAV file may be unusually small compared to the original file. This suggests truncating the CAV file contents when downloading or copying. The file should be downloaded again, making sure that the process has finished correctly.
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. The scan should cover the entire computer, not only the CAV file that we want to open. Sometimes virus-infected CAV 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 CAV 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. Some programs offer the ability to automatically repair CAV file corruption. You can restore the file from a backup or use Comodo Group help.
When reading, a message appears that the file was encrypted or corrupted. The encrypted file CAV 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.
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 CAV to a different directory.
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. Sometimes you have to wait for the session to the file CAV to close. However, some background programs may block the CAV file while scanning. If this does not work either, restart the device.
