Decrypme ransomware removal instructions
What is Decrypme?
Decrypme is a new variant of MedusaLocker ransomware. This malicious program was discovered by dnwls0719. Like most ransomware-type programs, Decrypme is designed to prevent victims from accessing their files by encrypting them. Typically, it is impossible to decrypt files without specific tools (decryption software and/or keys). To obtain them, victims are forced to pay a ransom. Instructions about how to recover files are provided in the "HOW_TO_OPEN_FILES.html" file. This ransomware also appends the ".decrypme" extension to all encrypted files. For example, "1.jpg" becomes "1.jpg.decrypme".
The "HOW_TO_OPEN_FILES.HTML" file is opened in a browser window and states that it is possible to recover (decrypt) files with a decryption tool held only by the developers of Decrypme. To contact these cyber criminals, victims must send an email to email@example.com or firstname.lastname@example.org. The criminals should then provide instructions about how to make payment. Victims are asked to provide a personal ID and are offered free decryption of one file, which can be attached to the email message. They are warned not to attempt to decrypt files using third party tools, since this will cause permanent data loss. It is impossible to restore files without valid tools provided by the developers. Despite this, never trust or pay these people - they often send no decryption keys/software, even if victims meet all demands. Typically, the only way to recover files is to restore them from a backup created before the ransomware attack. Removal of this malware only prevents it from causing further encryption - all previously-encrypted files remain in this state.

Most ransomware-type programs are all similar - they lock (encrypt) data and provide victims with instructions about how to pay ransoms and other details. Some examples of other software of this type include JayTHL, Nakw, and Xda. Main differences are usually cost of decryption software/key and cryptographic algorithm (symmetric or asymmetric) used to block access to data. Unfortunately, most of these programs perform encryption that is impossible to 'crack'. Therefore, victims cannot decrypt their files without tools held only by the cyber criminals (developers of specific ransomware). Typically, the only way to recover files free of charge is to restore them from a backup. Therefore, have your data backed up and store it on a remote server (Cloud) or unplugged storage device.

To eliminate possible malware infections, scan your computer with legitimate antivirus software. Our security researchers recommend using Malwarebytes.
How to protect yourself from ransomware infections
Do not download or install any programs or files using third party software downloaders, installers, or other such tools (other examples are provided above). The safest way is to use official and trustworthy websites. Update installed software through implemented functions or tools designed by official developers. Website links and/or files included in irrelevant emails should not be opened. Typically, these emails are sent from unknown, suspicious addresses and disguised as important, official. Licensed (paid) software should be activated properly. It is illegal to use third party ('cracking') tools and they often cause damage to computers by installing malware. Scan operating systems with reputable antivirus or anti-spyware software and keep it up-to-date. If your computer is already infected with Decrypme, we recommend running a scan with Malwarebytes for Windows to automatically eliminate this ransomware.

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 Decrypme 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 Decrypme 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 Decrypme 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 Decrypme 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, and 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.
