Tilde ransomware removal instructions
What is Tilde?
Tilde is a piece of malicious program, classified as ransomware. Credit for this malware's discovery belongs to dnwls0719. During the encryption process, all affected files are appended with the ".~~~~" extension. For example, a file originally named as something like "1.jpg" would appear as "1.jpg.~~~~" - following encryption. Once this process is complete, a ransom note - "Read~ME.txt" is dropped into every compromised folder.
The text presented in the "Read~ME.txt" file, informs victims that their data has been encrypted. The message states that all attempts of manual decryption will result in permanent data loss. To recover the files, users are to pay an unspecified ransom for the decryption tools/software. To learn how to do this, victims are to establish contact with the cyber criminals behind Tilde, via email. Users' letters are to contain the ID assigned to them in the subject/title field. In many cases of ransomware infections, without the interference of the criminals responsible for the attack - decryption is impossible. It might be, if the malware is still in development and/or has significant bugs (flaws). Whatever the case, it is expressly advised against meeting the ransom demands. Since often, despite paying - victims do not receive the promised decryption tools/software. Therefore, their files remain encrypted and worthless, and users experience financial loss. Removing Tilde will prevent it from further encryptions. Unfortunately, removal will not restore already affected data. The only viable solution is recovering the files from a backup, if one was created prior to the infection and was stored in a different location.
Screenshot of a message encouraging users to pay a ransom to decrypt their compromised data:
Ransomware is designed to encrypt data and demand payment for the decryption. Random Ransom, Revon, CCD and BlackOrchid are a couple examples of such malware. These malicious programs/infections have several key differences in-between them: the cryptographic algorithm they use (symmetric or asymmetric) and the ransom size. The demanded payments typically range between three and four digit sums (in USD). Digital currencies (e.g. cryptocurrencies, pre-paid vouchers, etc.) are usually used for the ransoms, due to transactions of them being difficult/impossible to trace. It is recommended to keep backups in remote servers and/or unplugged storage devices - to ensure data safety.

How to protect yourself from ransomware infections?
Suspicious and/or irrelevant emails should not be opened, especially any attachments (or links) present in them - as that can lead to a high-risk infection. Only official and verified download channels should be used. It is also recommended to alway activate and update products with tool/functions, provided by legitimate developers. Illegal activation ("cracking") tools and third party updaters are advised against use, since they are commonly used to proliferate malware. Due to dubious/malicious content and sites promoted by intrusive adverts, it is important to exercise caution when browsing. To ensure device and user safety, it is crucial to have a reputable anti-virus/anti-spyware suite installed and kept up-to-date. Furthermore, this software is to be used for regular system scans and removal of detected threats/issues. If your computer is already infected with Tilde, 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 Tilde 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 Tilde 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 Tilde 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 Tilde 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.
