Metan ransomware removal instructions
What is Metan?
Metan belongs to the GarrantyDecrypt ransomware family and was discovered by Michael Gillespie. It is categorized as ransomware, a program used by cyber criminals to prevent users from accessing their files by encrypting data stored on their computers. These computer infections allow developers (cyber criminals) to blackmail victims by making ransom demands. Metan renames all encrypted files by adding the ".metan" extension. For example, "1.jpg" becomes "1.jpg.metan". It also creates a ransom message within a text file ("#HOW TO DECRYPT FILES#.txt"), which can be found in folders that contain encrypted files.
According to the ransom message, all files were encrypted. To receive instructions on how to pay for a decryption tool, Metan's victims are encouraged to contact the developers via the firstname.lastname@example.org email address (the message must include a personal/unique ID). Generally, cyber criminals send a cryptocurrency wallet address for users to make the transaction and promise to send a decryption tool once they receive payment. Despite this, ransomware developers cannot be trusted, since they often do not send any decryption tools and people who pay them become victims of a scam. Unfortunately, they ensure that it is impossible to decrypt files without using their decryption tools. Their ransomware-type programs encrypt data using 'uncrackable' cryptography algorithms (symmetric or asymmetric). Therefore, only ransomware developers have access to tools capable of file decryption. If a computer is infected with ransomware, the best free way to regain access to files is to use a data backup and restore everything from there.

Metan is similar to many other programs of this type including Robbinhood, Mr-X666, and Doples. These computer infections are created by different cyber criminals, however, most encrypt data and make ransom demands. Main differences are usually cost of decryption/ransom size and cryptography used to encrypt data. Unfortunately, manual decryption is generally impossible. Therefore, ransomware victims are encouraged to contact cyber criminals and purchase decryption tools. Decryption without the involvement of specific ransomware developers is possible only when these programs are not fully developed (have bugs, flaws, and so on). Therefore, we recommend that you maintain backups and have them stored on unplugged storage devices or remote servers such as Cloud. If not, they are encrypted with other files stored on the computer.
How did ransomware infect my computer?
|Threat Type||Ransomware, Crypto Virus, Files locker.|
|Symptoms||Cannot open files stored on your computer, previously functional files now have a different extension (for example, my.docx.locked). A ransom demand message is displayed on your desktop. Cyber criminals demand ransom payment (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 Metan virus our malware researchers recommend scanning your computer with Spyhunter.
How to protect yourself from ransomware infections?
To avoid ransomware-type and other computer infections, browse the internet, install, download and update software carefully. Do not open attachments in emails received from unknown/untrustworthy addresses, since rogue files are often included with irrelevant emails. To safely update your software or the operating system, use implemented functions or tools provided by official developers. Do not use untrustworthy or unofficial websites, third party downloaders, or other channels as sources to download software. The safest way to download is from official websites and using direct links. Do not trust software 'cracking' tools, since this is a cyber crime and, furthermore, they are often the reason behind various computer infections. Finally, have a reputable anti-spyware/anti-virus software installed and enabled. If your computer is already infected with Metan, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

Log in to the account infected with the Metan virus. Start your Internet browser and download a legitimate anti-spyware program. Update the anti-spyware software and start a full system scan. Remove all entries detected.
If you cannot start your computer in Safe Mode with Networking, try performing a System Restore.

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 Metan 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 Metan 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 Metan 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 Metan ransomware.
Note that Windows 10 Fall Creators Update includes a "Controlled Folder Access" feature that blocks ransomware attempts to encrypt your files. By default, this feature automatically protects files stored in the 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 is more information on how to get this update and add an 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.
