What is the .CTF File Extension?

.CTF File Extension Description:

The file with a .ctf extension is used by AVG Antivirus, which is developed and distributed by Grisoft, and is described as an Update Control File. The main function of files ending in the .ctf format is to assist in the updating of virus definitions, as well as patches that will embed features into the AVG Antivirus program.

The only CTF file being used by AVG is avg6info.ctf, and this may vary in filename, depending on the version of the software used by your system. The data inside the file with a CTF extension contains all the necessary information to update your antivirus program, such as:

* d600ppxe.bin

* d6032pgl.bin

* d6032lhj.bin

* u612lztc.bin

* u612m6rc.bin

* u612m9ds.bin

* u612m9jc.bin

The other data included in the file with the CTF format are date and time of update, date and version of the file above, address of the server, the protocol to be used, and more.

The AVG Control Center, or the main GUI of the application, will automatically initiate the download of updates, as defined in the CTF file. If this returns an error, or if the updating process fails, the user can initiate the download manually. if necessary.

There are certain instances where errors in updating return the message "Update Control File is damaged," possibly because of the following reasons:

* The file with the CTF extension is not found in its original location

* The CTF file contains data that doesn't coincide with the version of your AVG Antivirus

* Or the server address that is found inside the CTF file is unreachable.

Other reasons for this error can be due to Internet connection restrictions in your system, which disables the application from downloading the necessary files, as stated in the CTF file.
