Anatova ransomware removal instructions

What is Anatova?

Anatova was discovered by Valthek and is categorized as ransomware-type malicious program. Anatova is different from other infections of this type, since it does not add an extension to the names of encrypted files and leaves their icons unchanged. This program simply makes files unusable (after encryption, files cannot be opened) and creates a ransom-demand message within the "ANATOVA.TXT" text file. The name of the ransom message can differ depending on the version of Anatova ransomware.

The message within the "ANATOVA.TXT" file informs victims that all files are encrypted, and to decrypt them, they must purchase a decryption tool at a cost equivalent to 10 DASH cryptocoins. This can be purchased by transferring the required amount of cryptocurrency to the wallet address provided. When payment is received, Anatova's victims must send the address used to make payment and an unedited "ANATOVA.TXT" file (or other ransom message) to one of the following email addresses: or They offer free decryption of one JPG (.jpg) file no larger than 200Kb as 'proof' that they have the correct tool for successful decryption. Most cyber criminals who design and spread ransomware-type infections use cryptographies (symmetric or asymmetric) that generate unique keys. Therefore, each victim receives an individual key, and no other key will work. Furthermore, cyber criminals store the keys on remote severs controlled only by them. They use cryptographies that are impossible to 'crack', and thus ransomware victims are left with no other option but to contact cyber criminals. Note that these people can never be trusted - they often ignore victims once they receive the cryptocurrency ransom (or other form of payment). In this way, people are scammed. Unfortunately, there are no tools currently capable of decrypting Anatova's encryption free of charge. The best option in this case is to use an existing data backup and restore everything from there.

There are many ransomware-type infections promoted under different names. For example, Ppam, Mdk4y, and Crypt0r). Most have similar behavior - these malicious programs encrypt data and display ransom-demand messages. Some common differences are ransom size, decryption tool, and cryptography used to encrypt data. These cryptographies are generally impossible to crack, unless the ransomware is not fully developed (has bugs/flaws - this is not very common). Therefore, we recommend that you maintain regular data backups and store them on remote servers or unplugged storage devices.

How did ransomware infect my computer?

Anatova's developers proliferate this ransomware-type infection using spam (email) campaigns, trojans, fake software updaters, or untrustworthy software download sources. Ransomware developers use spam campaigns to proliferate various infections using malicious attachments. Typically, they attach a malicious file (for example, Microsoft Office document, archive file, PDF, executable, or other) to an email and hope that some recipients will download and open it. Once opened, these attachments download and install computer infections such as Anatova or other viruses. Trojans, on the other hand, must already be installed. Following infiltration, they cause chain infections - these programs proliferate other malware. Fake software updaters cause infections by downloading and installing computer viruses rather than the expected updates or by exploiting outdated software bugs or flaws. Various free file hosting and freeware download websites, peer-to-peer networks (such as torrent clients, eMule, etc.) and other third party software download sources are also used by cyber criminals. They present infected files as legitimate in attempts to trick people into installing computer infections.

Threat Summary:
Name Anatova virus
Threat Type Ransomware, Crypto Virus, Files locker
Symptoms Can't open files stored on your computer, previously functional files now have a different extension, for example my.docx.locked. A ransom demanding message is displayed on your desktop. Cyber criminals are asking to pay a ransom (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 Anatova virus our malware researchers recommend scanning your computer with Spyhunter.

How to protect yourself from ransomware infections?

Manage all received emails carefully, especially those that contain attachments or web links. If an email is received from an unknown/suspicious address, do not open the attachment or link without studying it first. Download software using direct links, trustworthy (official) sources only. Do not use third party downloaders, installers - in some cases, these sources proliferate rogue applications that might cause computer infections or other problems. Do not use any of the aforementioned software download sources. Update software using tools or implemented functions provided by official software developers. Do not use third party updaters. Finally, have reputable anti-virus/anti-spyware installed and keep it enabled at all times. These tools can detect and remove threats before any damage is done to the system/computer. If your computer is already infected with Anatova, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

Text presented in Anatova ransomware text file ("ANATOVA.TXT"):

4. In the opened window, click "Next".

restore system files and settings

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 Anatova ransomware virus infiltrating your PC).

select a restore point

6. In the opened window, click "Yes".

run system restore

7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining Anatova 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 Anatova 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.

Restoring files encrypted by CryptoDefense

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 regain control of the files encrypted by Anatova, you can also try using a program called Shadow Explorer. More information on how to use this program is available here.

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 Anatova 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.

Controll Folder Access

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:
