VDF, known as Virus Definition File, is a .VDF file type associated with AntiVir antivirus program. VDF files are used as a source of virus information and contain updated virus signatures, detection methods, and other information that is used to detect malicious software. It helps the software update itself with the latest virus definitions signatures as it is released so that users can be better protected against the latest malicious threats.
The structure of these files is optimized for quick retrieval of the signature data and antivirus programs use this format to extend their capability to quickly find an infection in a file or folder. Typically, a VDF file contains all the definitions of the scanned for viruses, divided into different categories, such as worms or Trojans. Additionally, the file contains version code, manufacturer name, names of spyware products and databases from which the information was gathered.

Programs for WINDOWS system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .VDF) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .VDF extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .VDF file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .VDF extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .VDF extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .VDF file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .VDF file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .VDF file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .VDF file) will be extended to the maximum.
It is also good to check
- if the .VDF file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
