2.Decrypt Your Files

Fortunately for all our sake, Kaspersky have kindly provided the users with a free decryptor. It is called RakhniDecryptor and you can download it from Kaspersky’s virus fighting utilities page.

Here is how to decode your files using RakhniDecryptor:

Step 1: Download and start the RakhniDecryptor.exe:

start scan

Step 2: Click on the “Start Scan” button. It will open a window from which you can select a file to decrypt.

Untitled

Step 3: Look for files that are more important to you first and select them to start the decryption process. This is because it may take some time. A good strategy is to attempt decrypting files that are smaller in size. This is because if the files have the same password other larger files can be automatically decrypted by the tool using the same password.

Step 4: Set your computer’s settings to prevent it from automatically shutting down. Here is how to stop your PC from shutting down.

1) Press +R and then type “powercfg.cpl”.

powercfg

2) After the power plan window has opened go to Change plan settings for your current power plan.

Power Options

3) After you are there, set everything to “Never” from the drop-down menus and then “Apply” it.

edit-plan-settings

4) Close the Change plan settings Window and reopen it. Everything should look saved to “Never“. After this is done click on the blue highlighted text saying “Change advanced power settings”.

Advanced Power Options

5) Check the Hard Disk option and if there are remaining times, switch them to never by clicking on the highlighted text like the picture above shows.

Finally, click on Apply and close it and you are done. Make sure your computer is plugged in the AC and the Power Plan with the changed settings is active. Decryption may take from several hours to several days, it really depends. But we urge users to keep trying to decrypt their files and NOT pay the ransom money by the Doctor@freelinuxmail.org ransomware. This is because for one there is no guarantee the cyber-criminals will give you the decryption keys back and also by paying you fund their operation.

NOTE! Substantial notification about the Doctor@freelinuxmail.org threat: Manual removal of Doctor@freelinuxmail.org requires interference with system files and registries. Thus, it can cause damage to your PC. Even if your computer skills are not at a professional level, don’t worry. You can do the removal yourself just in 5 minutes, using a malware removal tool.
