Before going into the details of the virus removal and file recovery process, let’s know about it a bit more.
What is Cerber Ransomware Virus?
Cerber virus is a malicious computer malware that uses the AES encryption algorithm to encode files on the victim’s computer. It penetrates in the system and encrypts various file types some of which are JPG, DOC, RAW, and AVI. With encryption, each file gets a .cerber extension that is also called infectious extension. Some of its variants also add .cerber2 and .cerber3 extension to the affected files. Not just these, some of its variants also add random file extensions such as .a37b, .a563, .ba99, .98a0, etc.
After encryption, a process that makes the affected files unreadable, the virus demands a ransom to decrypt them. Many times, it is stated that the payment must be within a limited time frame, usually seven days, else the ransom amount would get doubled. Also, some of its variants reveal their versions as well. For instance, Cerber Ransomware 4.1.5, Cerber Ransomware 4.1.6, and Cerber Ransomware 5.0.0 that is the latest variant and demands a ransom of $499.
Like any other ransomware type of virus, you may accidentally download it through malicious spam emails carrying an executable virus file.
An In-Depth into Cerber Ransom-Virus
During encryption, the Cerber virus creates three different files that are as follows:
#DECRYPT MY FILES#.txt
#DECRYPT MY FILES#.html
#DECRYPT MY FILES#.vbs
These contain payment instructions in a step-by-step manner. These files have messages stating that users can decrypt the encrypted files only using the Cerber Decryptor. Out of these three files, the #DECRYPT MY FILES#.vbs file contains a VBScript. When it is executed, it displays the following message: “Your documents, databases and other important files have been encrypted!” To download the decryptor, you should make a payment of $xxx.xx. If you delay the payment beyond 7 days, the amount will double.
It is also stated that you can pay only using the Tor browser and by following instructions as indicated on the website titled “Cerber Decryptor”. If you are the victim, you can select your preferred language and then proceed to the financial part of the fraud. Although any efficient file recovery mechanism has not been devised yet, you can employ certain techniques that are valuable regarding removing the Cerber virus and recover encrypted files.

Secondly, you simply need to ship the device and ask the file recovery service provider to recover encrypted excel files.
The Way Forward – Stellar Data Recovery
The above-explained methods are the three ways by which you can recover data encrypted by ransomware virus. You can use any of them for best results. However, restoring from a backup file is possible only if you have created one. Also, it is a time-consuming process and requires a thorough knowledge of the restoration process. Again, all file recovery software tools are not capable of decrypting files from the ransomware. Even if a few are, you need to know the proper steps to run it properly so that it gives the desired results. On the other hand, obtaining data and file recovery services, particularly from Stellar Data Recovery simply requires contacting its closest branch.
