Oled ransomware removal instructions
What is Oled?
Oled ransomware was discovered by S!Ri. Typically, software of this type encrypts files, renames them and creates a ransom note. Oled renames encrypted files by adding victim's ID and developer's email address and appending the ".oled" extension to their filenames. For instance, it renames "1.jpg" to "1.jpg.[EF7BE7BC].[firstname.lastname@example.org].oled", and so on. Also, Oled creates a ransom note, a text file named "readme-warning.txt".
As stated in the ransom note ("readme-warning.txt"), victims have to pay for a decryption tool in Bitcoins. However, price of this tool is not mentioned. In order to get more details (like price of a decryption tool and how to pay for it) victims have to write an email to email@example.com, it can contain up to two unimportant files as well. According to Oled's developers, they will decrypt those files and send them back. They offer free decryption as a proof that they have a tool that can decrypt files encrypted by Oled ransomware. Also, victims are warned no to try to modify any of encrypted files or use other decryption tools because may cause irreversible data loss. Typically, cyber criminals behind a particular ransomware are the only ones who have tools that can decrypt files encrypted by it. Unfortunately, that is the case with Oled too - there are no free tools that could be capable of decrypting files encrypted by this ransomware, at least not at the moment. As a rule, the only one way to recover files without having to use tools that can be purchased from cyber criminals is to restore them from a created backup. It is worth mentioning that files remain encrypted even after removing ransomware from the operating system. Its removal only prevents it from causing further encryptions. We strongly recommend to recover files using a backup (if there is one created) and not to pay cyber criminals for a decryption tool because they may not send it. Quite often victims of ransomware who trust cyber criminals (pay them a ransom) get scammed.

More examples of software that is classified as ransomware are Adair, Jenkins and Afrodita. In most cases programs of this type are designed to prevent victims from accessing their data by encrypting them and to provide instructions (create ransom notes) on how to pay for a decryption tool and/or key. Usually the main variables are size of a ransom and cryptographic algorithm (symmetric or asymmetric) that ransomware uses to lock files. Unfortunately, most programs of this type encrypt files with strong encryption algorithms and it is impossible to decrypt files without the right tools unless ransomware is still in a development state (has some vulnerabilities). However, it does not happen often and that is why it is important to always have data backed up and keep it on a remote server and/or unplugged storage device.

|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 malware infections our security researchers recommend scanning your computer with Spyhunter.
How to protect yourself from ransomware infections?
It is recommended to not to download and install any software through third party downloaders, installers, unofficial pages and other sources that are mentioned in the paragraph above. It should be done by using only official ages and direct download links. Furthermore, installed software and operating system must be updated via implemented functions and/or tools that are designed by official developers. Attachments (or web links) in received irrelevant emails that are sent from unknown, suspicious addresses should not be opened. No software or operating system should be activated through software unofficial activation tools. It is not legal to bypass activation of software this way and it often leads to installation of high-risk malware. One more important thing is to regularly scan a computer for threats with a reputable anti-spyware or antivirus software and always keep it up do date. If your computer is already infected with Oled, we recommend running a scan with Spyhunter 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 Oled 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 Oled 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 Oled 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 Oled 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.
