TFlower ransomware removal instructions
What is TFlower?
Discovered by GrujaRS, TFlower is software categorized as ransomware. Unlike most ransomware-type programs, it does not change extensions of encrypted files. It does, however, create a ransom message (within a text file named "!_Notice_!.txt") that contains instructions about how to purchase a decryption tool. Typically, programs such as TFlower encrypt (lock) files, which then cannot be accessed unless they are decoded with a decryption tool (that cyber criminals encourage victims to purchase).
The ransom message ("!_Notice_!.txt") states that files can only be decrypted with the key that was used to encrypt them. To obtain a decryption tool, victims are encouraged to pay TFlower developers a ransom of 15 BTC (Bitcoin). To make this transaction, they must use the BTC wallet address provided in the ransom message. The message also contains a Tor website address that can be used for free decryption of one file, and an email address (email@example.com) that can be used to contact the cyber criminals who designed TFlower ransomware. 15 Bitcoins is a large sum of money, however, even if this is paid, there is a high probability that developers will not send tools to decrypt the files. Cyber criminals cannot be trusted, and people who do trust them are often scammed. Generally, only ransomware developers have the correct decryption tools/keys. Most ransomware-type programs perform encryptions that are impossible to decrypt without the involvement of cyber criminals. The only free way to retrieve files is to restore them from a backup, however, this is possible only when a backup exists (created prior to infection with ransomware).

Other ransomware examples are Format, Access, and Ndarod. Most of these programs have similar behavior: they encrypt data and create ransom messages that contain instructions about how to decrypt files (purchase tools required for decryption). Common differences are size of ransom (cost of a decryption tool/key) and cryptographic algorithm (symmetric or asymmetric) used to encrypt data. Typically, files cannot be decrypted without the correct tools and paying for them. In rare cases, encryptions can be 'cracked', but only when ransomware has bugs/flaws or other vulnerabilities. To prevent data and financial loss caused by these programs, maintain backups and keep them stored on a remote server or unplugged storage device.

To eliminate TFlower virus our malware researchers recommend scanning your computer with Spyhunter.
How to protect yourself from ransomware infections?
Do not open files that are attached to irrelevant emails or when the emails are received from unknown, suspicious addresses. Download files and programs from official and trustworthy websites. Do not use the sources mentioned above. Keep the operating system and installed software up-to-date, however, use tools and implemented functions created by official developers. The same applies to software activation: 'cracking' tools are illegal and cyber criminals often use them to distribute malware. Keep your computer secured with a reputable anti-virus or anti-spyware suite. If your computer is already infected with TFlower, 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 TFlower 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 TFlower 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 TFlower 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 TFlower 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:
