MegaLocker ransomware removal instructions
What is MegaLocker?
MegaLocker ransomware is designed to prevent its victims from accessing files/data by encrypting them. In most cases programs of this type encrypt files stored on a computer. However, once after infiltrating a computer, MegaLocker searches for connections to Samba servers and attempts to guess passwords used to connect to them. In other words, it causes a brute-force attack. After successful attack it encrypts files stored on hacked servers. In order to decrypt locked data stored on Samba servers, victims are urged to pay cyber criminals a ransom. Ransom note can be found in a text file named "! DECRYPT_INSTRUCTION.TXT", MegaLocker puts this file in every folder that contains any encrypted data. It also adds the ".crypted" extension to every encrypted file. For example, it changes "1.jpg" file to "1.jpg.crypted" and so on.
As stated in "! DECRYPT_INSTRUCTION.TXT" file, MegaLocker encrypts files using AES cbc-128 cryptography algorithm. To decrypt them, victims must purchase a decryption tool which costs either $250 or $1000 (the price was updated, increased from $800 to $1000). A lower price is for regular users, a higher one is for companies. To get more details on how to make a payment victims have to contact cyber criminals via email@example.com. One way or another, it is stated that there is no other tool that could be capable of decrypting encryption caused by MegaLocker ransomware. To pay for the tool victims are encouraged to purchase cryptocurrency (Bitcoins) and transfer it to a provided Bitcoin wallet address. Besides, these cyber criminals offer a free decryption of up to three files. Victims can send them via aforementioned email address. However, even if MegaLocker's have the decryption tool (most probably they do), it is very likely that they will not send it even if their demands to pay a ransom will be met. For this reason we do not recommend to contact and trust them, and/or pay them any money/cryptocurrency. Since there is not tool that could be capable of decrypting files encrypted by MegaLocker for free, we recommend to use data backup and to restore everything from there. As a rule, encryptions caused by ransomware-type programs are impossible to 'crack' without using tools that only particular ransomware's developers have.

Spyhunter, Raldug, Carcn (and many others) are just a few examples of other malicious programs that are quite similar to MegaLocker. Typically, these programs are designed to serve two purposes: to encrypt data and demands to pay a ransom through ransom notes. In most cases main differences are the cost of a decryption tool or key and cryptography algorithm that was used to encrypt victim's data. Despite all similarities or differences, most ransomware-type programs are impossible to 'break' without interference of cyber criminals. Decryptions without using tools that only they have are possible only if ransomware is not fully developed/has some bugs, flaws. That is why we recommend to use create data backups regularly. Besides, they should be stored on remote server or unplugged device, otherwise they will be encrypted together with other data that is stored on a computer.
How did ransomware infect my computer?
|Threat Type||Ransomware, Crypto Virus, Files locker|
|Encrypted Files Extension||.crypted|
|Ransom Demanding Message||! DECRYPT_INSTRUCTION.TXT text file|
|Ransom Amount||$250, $800|
|Cyber Criminal Contactfirstname.lastname@example.org|
|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 MegaLocker virus our malware researchers recommend scanning your computer with Spyhunter.
How to protect yourself from ransomware infections?
To protect accounts and servers we recommend to use long and strong passwords that would include random characters. They should not contain personal details (birthdays, names and so on). Additionally, servers should be protected using two layers of protection/two different passwords. Furthermore, to avoid computers infected with various viruses we recommend to browse the web, install, download and update all software with care. Do not open various attachments or web links that are presented in emails received from unknown, suspicious addresses. These emails usually are presented as legitimate and official, however in most cases they are irrelevant too. Moreover, update installed software (operating system) using functions or tools that are provided by official developers. None of the other (unofficial) tools should be trusted or used. Avoid downloading software from untrustworthy and unofficial websites, using various third party downloaders and other sources that we mentioned above. Safest way to download it is using official websites and direct download links. Software cracking tools should not be used as well, they often download and install malicious programs. Another important thing to know about them is that usage of these tools is a cyber crime. Another significant thing is to have a reputable anti-spyware or anti-virus software installed and to keep it enabled (at all times). If your computer is already infected with MegaLocker, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

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 MegaLocker 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 MegaLocker 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 MegaLocker 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 MegaLocker ransomware.
Note that Windows 10 Fall Creators Update includes "Controlled Folder Access" feature that blocks ransomware attempts to encrypt your files. By default this feature automatically protects files stored in Documents, Pictures, Videos, Music, Favorites as well as Desktop folders.
Windows 10 users should install this update to protect their data from ransomware attacks. Here's more information on how to get this update and add additional protection layer from ransomware infections.
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.
