What is a .EFDC file?
An .EFDC file is a type of file that has been taken over and locked by a specific kind of harmful software called EFDC ransomware. This ransomware is a type of computer virus created by cybercriminals. It targets regular files on your computer—like documents, music files, videos, or pictures—and changes them by encrypting them and renaming them with an .EFDC extension. This means the original files are converted into a format that you cannot open or use until they are decrypted (returned to their original state).
The EFDC ransomware typically leaves a message for the computer owner in a file named _readme.txt, which can be found in any folder that contains the encrypted files. This message includes instructions that the cybercriminals expect the victim to follow, usually involving payment to get the files decrypted.
This type of ransomware, including the EFDC variant, often gets onto computers through deceptive means. It might be hidden within software that seems legitimate but is actually designed to install harmful programs on your computer. For example, if you download and install a program from an untrustworthy source, it might include the EFDC ransomware.
As for opening .EFDC files, under normal circumstances, you cannot open them because they are encrypted. The only recommended method to potentially restore your files is by using system restore options or backup copies if available. It is important to note that paying the ransom does not guarantee that your files will be restored.
