ANIMUS ransomware removal instructions
What is ANIMUS?
ANIMUS is a ransomware-type virus discovered by malware security researcher, Karsten Hahn. This virus is designed to stealthily infiltrate the system and encrypt most stored files using the RSA-2048 encryption algorithm. During encryption, ANIMUS appends filenames with the ".animus" extension (for example, "sample.jpg" is renamed to "sample.jpg.animus"). Compromised data immediately becomes unusable. Once encryption is over, ANIMUS creates three identical text files ("ANIMUS_RESTORE.txt", "ANIMUS_RESTORE2.txt", and "ANIMUS_RESTORE3.txt") and places a copy of each in all existing folders.
As mentioned above, the new text files are identical. All contain a message stating that data is encrypted. To decrypt data, victims must purchase a unique decryption key. Unfortunately, ANIMUS uses RSA-2048 - a complex asymmetric encryption algorithm that generates two keys (public [encryption] and private [decryption]). Restoring data without the private key is impossible. All private keys are stored on a remote server and users are encouraged to pay a ransom of $100 in Bitcoins for their release. As compared to other ransomware, this cost is quite low, since they typically fluctuate between $500 and $1500. In any case, ransoms should not be paid. Research shows that cyber criminals are likely to ignore victims, once payments are submitted - paying typically gives no positive results and users are scammed. Therefore, ignore all requests to contact these people and certainly do not submit any payments. Unfortunately, there are no tools capable of cracking RSA-2048 cryptography and restoring data free of charge. Therefore, the only solution is to restore everything from a backup.

The Internet is full of ransomware-type viruses similar to ANIMUS including Nozelesn, KRAB, and Omerta - these are just some examples from many. Research shows that although these viruses are developed by different cyber criminals, their behavior is identical - all encrypt data and make ransom demands. The only major differences are size of ransom and type of encryption algorithm used. Unfortunately, most are developed to use algorithms (RSA, AES, and other) that generate unique decryption keys. Therefore, file decryption manually without involvement of developers (contacting these people is not recommended) is mostly impossible. The only possible scenarios are ransomware not being fully developed or having certain bugs/flaws (the key is hard-coded, stored locally, or similar). Ransomware presents a strong case for maintaining regular data backups, however, it is very important to store them in on a remote server (e.g., Cloud) or an unplugged storage device (Flash drive, external hard drive, or similar). This will prevent ransomware from encrypting backups together with regular data.

How to protect yourself from ransomware infections?
Careless behavior and lack of knowledge are the main reasons for computer infections. The key to safety is caution. Therefore, pay close attention when browsing the Internet and downloading/installing/updating software. You are strongly advised to carefully analyze all received email attachments. Files that seem irrelevant or have been received from a suspicious email address should never be opened. Download your programs from official sources only, using direct download links. Third party downloaders/installers often include rogue apps, and thus should not be used. The same applies to updating software. It is very important to keep installed applications up-to-date, however, this should be achieved through implemented functions or tools provided by the official developer only. Having a reputable anti-virus/anti-spyware suite installed and running is also essential. If your computer is already infected with ANIMUS, we recommend running a scan with Reimage Repair Tool for Windows to automatically eliminate this ransomware.

SORRY! Your files are encrypted.
File contents are encrypted with random key.
Random key is encrypted with RSA public key (2048 bit).
We STRONGLY RECOMMEND you NOT to use any "decryption tools".
These tools can damage your data, making recover IMPOSSIBLE.
Also we recommend you not to contact data recovery companies.
They will just contact us, buy the key and sell it to you at a higher price.
If you want to decrypt your files, you have to get RSA private key.
In order to get private key, write here:
Attach file is 000000000.key from %appdata% to email message,
without it we will not be able to decrypt your files
And pay 100$ on 1G5TThb5tcJ3LQbF4C4Tibgd9y7m3iYPFH wallet
If someone else offers you files restoring, ask him for test decryption.
Only we can successfully decrypt your files; knowing this can protect you from fraud.
You will receive instructions of what to do next.

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 ANIMUS 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.
