.cav File Extension

Developer: Comodo Group
File type: Comodo Virus Definitions File
You're here because you have a file that has a file extension ending in .cav. Files with the file extension .cav can only be launched by certain applications. It's possible that .cav files are data files rather than documents or media, which means they're not meant to be viewed at all.

what is a .cav file?

Pieces of data classified as virus definitions are stored in files referenced by the associated anti-virus software. The anti-virus application references the data in those files when a user updates the program or when the software is scanning and monitoring the system for possible viruses and other malicious applications. This is also done by the anti-virus program when a user accesses certain integrated features that correspond to the functions of the data in those virus definitions. The Comodo Internet Security software can be installed into a Microsoft Windows-based system to implement support for files appended with the .cav extension. This software uses these CAV files as database and update files, since the content stored in these CAV files are updated virus definitions from the Comodo Group, developer of the Comodo Internet Security software. Signature data of specific malicious applications classified as viruses among other malware types is found in these CAV files, and this data is used by the Comodo Internet Security software to recognize possible viruses in the Microsoft Windows system.

how to open a .cav file?

Launch a .cav file, or any other file on your PC, by double-clicking it. If your file associations are set up correctly, the application that's meant to open your .cav file will open it. It's possible you may need to download or purchase the correct application. It's also possible that you have the correct application on your PC, but .cav files aren't yet associated with it. In this case, when you try to open a .cav file, you can tell Windows which application is the correct one for that file. From then on, opening a  .cav file will open the correct application.

a word of warning

Be careful not to rename the extension on .cav files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.

what is a file extension?

A file extension is the set of three or four characters at the end of a filename; in this case, .cav. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
