Fdcz Virus – More Information
Fdcz virus is a part of one of the most active ransomware virus families out there, known as STOP/DJVU. This virus family includes some other recently detected threats, like the Reig, Ygkz and Plam ones.
But how did the Fdcz virus end up on your computer? Well, the answer to this is rather simple.
One possible scenario which accounts for more than 80% of ransomware infections out there is if the file that infects computers is sent to you via e-mail. If so, this file may conveniently pretend to be an invoice, order confirmation, flight ticket or other very important document that you are motivated into opening. Once this e-mail attachment is downloaded and ran, infection with the virus is immediate.
Another way you may have become a victim of the Fdcz virus is if you have downloaded the infection file yourself. If so, then the virus may have seemed like it is some sort of a program, crack, patch, update or any other application available for free download. But, instead of what you are looking to download, you get this ransomware.
Once Fdcz is in your computer, it may run several administrative commands that allow it to download files and crate and modify files in it. This is how it may drop its virus modules, that may be located likely in some of the following directories in Windows:
- %Local%
- %AppData%
- %ProgramData%
- %Windows%
- %System%
- %LocalLow%
- %Temp%
- %system32%
- %Roaming%
Among the dropped files by this nasty threat on your computer is the ransom note, called _readme.txt. It has the following extortionist message directed towards victims:
The main activities of the Fdcz virus revolves around making sure all your backups are deleted and scanning for important files that you have in order to encrypt those. It may perform the following actions before you even realize its in your computer:
- Run as administrator.
- Obtaining read and write authorizations.
- Analyzing If it has infected your computer system previously and if so deletes itself.
- Establish a connection with the cyber-criminals running it.
- Creating Windows registry entries in the “Run” or “RunOnce” Registry sub-keys.
.fdcz Files
The files that are encrypted by the Fdcz virus are all types of data used by you, besides critical Windows components. This is done so that you can still use your computer to pay the ransom to the criminals who are behind this infection.
The files targeted for encryption are the following:
- Back-ups.
- Docs.
- Music.
- Videos.
- Pictures.
- Databases.
- Archives.
- Anything conserved in a USB or other drive.
These files are encoded by using Advanced Encryption Standard, also known as AES. This is a very tough cipher to crack and it changes blocks of data from the original file, to make it no longer functioning. The result of this encryption is that a unique decryptor key is generated that can reverse the process and make your files usable again. Keep reading this article if you want to learn proper ways to safely remove this ransomware and more options on recovering your files.

If you want to fully erase this virus from your computer, then the removal guide below will help you do that.
