My Decryptor ransomware removal instructions
What is My Decryptor?
My Decryptor (also known as Magniber) is a ransomware-type virus discovered by malware security researcher, Michael Gillespie. Once infiltrated, My Decryptor encrypts stored files and appends filenames with an extension comprising seven random characters. For instance, "sample.jpg" might be renamed to a filename such as "sample.jpg.gkelhoh". At this moment cyber criminals are using ".ypkwwmd", ".ndpyhss", ".wmfxdqz", ".axlgsbrms", ".nhsajfee", ".mqpdbn", ".damdzv", ".qmdjtc", ".mftzmxqo", ".demffue", ".dxjay", ".fbuvkngy", ".xhspythxn", ".dlenggrl", ".skvtb", “.vbdrj”, “.fprgbk”, ".ihsdj" or ".kgpvwnr" extensions for encrypted files. After successfully encrypting files, My Decryptor creates a text file ("_HOW_TO_DECRYPT_MY_FILES_[random_characters]_.txt", "READ_ME_FOR_DECRYPT_[victim’s id].txt") or READ_ME.txt, placing it on the desktop.
The text file contains a message stating that files are encrypted and can only be restored using a unique decryption tool together with a unique (private) key. Unfortunately, this information is accurate. It is currently unknown which cryptography My Decryptor ransomware uses, however, as the message mentions a "private" key, it is safe to assume that the encryption is asymmetric. Therefore, two keys (public [encryption] and private [decryption]) are generated. Cyber criminals store the private key on a remote server. Decryption without this key is impossible. Victims are encouraged to pay a ransom in exchange for the key and decryption tool - they are instructed to visit My Decryptor's website to receive these assets. The cost of decryption is .2 Bitcoin (currently equivalent to ~$1145). It is also stated that the ransom must be paid within five days, after which the cost will double. Be aware that cyber criminals cannot be trusted. Research shows that these people often ignore victims, once payments are submitted. Therefore, paying does not guarantee decryption of your files and there is a high probability that you will be scammed. As well as losing your money, you will support cyber criminals' malicious businesses. Therefore, we strongly advise you to ignore all requests to pay any ransoms. Unfortunately, there are currently no tools capable of restoring files encrypted by My Decryptor. The only solution is to restore your files/system from a backup.

My Decryptor shares many similarities with dozens of other ransomware-type viruses. The list of examples includes (but is not limited to) Anubi, BugWare, Asasin, and SyncCrypt. These viruses are developed by different criminals, however, their behavior is identical - all encrypt files and makes ransom demands. The only major differences are size of ransom and type of encryption algorithm used. Research shows that, unfortunately, most of these viruses employ algorithms (foe example, AES, RSA, etc.) that generate unique decryption keys. Therefore, unless the malware contains bugs/flaws or is not fully developed, file decryption manually (without involvement of developers - contacting these people is not recommended) is impossible. For these reasons, ransomware-type viruses such as My Decryptor present a strong case for maintaining regular data backups.
How did ransomware infect my computer?
|Name||My Decryptor virus|
|Threat Type||Ransomware, Crypto Virus, Files locker|
|Symptoms||Can't open files stored on your computer, previously functional files now have a different extension, for example my.docx.locked. A ransom demanding message is displayed on your desktop. Cyber criminals are asking to pay a ransom (usually in bitcoins) to unlock your files.|
|Distribution methods||Infected email attachments (macros), torrent websites, malicious ads.|
|Damage||All files are encrypted and cannot be opened without paying a ransom. Additional password stealing trojans and malware infections can be installed together with a ransomware infection.|
To eliminate My Decryptor virus our malware researchers recommend scanning your computer with Spyhunter.
How to protect yourself from ransomware infections?
To prevent ransomware infections, be very cautious when browsing the Internet. Never open files attached to emails sent from suspicious addresses. These emails should be deleted without reading. Furthermore, download your software from official sources only and, preferably, using a direct download link (third party download/installation tools often include malicious programs). Keep installed programs updated, however, note that criminals proliferate malware via fake updaters. Therefore, updating software via third party tools is very risky. Using a legitimate anti-virus/anti-spyware suite is essential. The main reasons for computer infections are poor knowledge and careless behavior - the key to computer safety is caution.

1. During your computer start process, press the F8 key on your keyboard multiple times until the Windows Advanced Options menu appears, and then select Safe Mode with Command Prompt from the list and press ENTER.
2. When Command Prompt mode loads, enter the following line: cd restore and press ENTER.
3. Next, type this line: rstrui.exe and press ENTER.
4. In the opened window, click "Next".
5. Select one of the available Restore Points and click "Next" (this will restore your computer system to an earlier time and date, prior to the My Decryptor ransomware virus infiltrating your PC).
6. In the opened window, click "Yes".
7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining My Decryptor ransomware files.
To restore individual files encrypted by this ransomware, try using Windows Previous Versions feature. This method is only effective if the System Restore function was enabled on an infected operating system. Note that some variants of My Decryptor are known to remove Shadow Volume Copies of the files, so this method may not work on all computers.
To restore a file, right-click over it, go into Properties, and select the Previous Versions tab. If the relevant file has a Restore Point, select it and click the "Restore" button.
If you cannot start your computer in Safe Mode with Networking (or with Command Prompt), boot your computer using a rescue disk. Some variants of ransomware disable Safe Mode making its removal complicated. For this step, you require access to another computer.
To protect your computer from file encryption ransomware such as this, use reputable antivirus and anti-spyware programs. As an extra protection method, you can use programs called HitmanPro.Alert and EasySync CryptoMonitor, which artificially implant group policy objects into the registry to block rogue programs such as My Decryptor ransomware.
HitmanPro.Alert CryptoGuard - detects encryption of files and neutralises any attempts without need for user-intervention:
Malwarebytes Anti-Ransomware Beta uses advanced proactive technology that monitors ransomware activity and terminates it immediately - before reaching users' files:
- The best way to avoid damage from ransomware infections is to maintain regular up-to-date backups. More information on online backup solutions and data recovery software Here.
