ANNABELLE ransomware removal instructions
What is ANNABELLE?
First discovered by Bart, ANNABELLE is a ransomware-type virus that stealthily infiltrates the system and encrypts most stored files. During encryption, this malware appends filenames with the ".ANNABELLE" extension (e.g., "sample.jpg" is renamed to "sample.jpg.ANNABELLE"). From this point, using files becomes impossible. Research results show that, after successfully encrypting files, ANNABELLE also performs various tasks to corrupt the system and, after rebooting it, locks the entire screen.
Research shows that once executed, ANNABELLE configures itself to run automatically on each system restart. It also terminates a number of running applications/processes (e.g., Google Chrome, Task Manager, MSConfig, etc.) In addition, ANNABELLE modifies IFEO (Image File Execution Options) so that users are unable to run various applications (such as web browsers, text editors, and so on). ANNABELLE is also designed to modify the system's MBR (Master Boot Record) so that users see a message giving credit to certain cyber criminals (responsible for ANNABELLE's development) on each system restart. Research also shows that ANNABELLE attempts to inject itself into removable drives (e.g., USB Flash Drive). ANNABELLE then performs a system restart and, as mentioned above, locks the computer screen and displays a ransom-demand message.
The message informs victims about the encryption and states that decryption supposedly requires keys generated uniquely for each victim. Therefore, to receive a key, each victim must pay a ransom of .1 Bitcoin (currently worth of ~$1000). After submitting payment, users will supposedly be able to decrypt their data. Fortunately, ANNABELLE is developed to use a hard-coded key. In other words, it uses the same key to encrypt all victims' files. Therefore, there is no need to pay any ransom. Malware security researcher Michael Gillespie has released a decryption tool capable of restoring files encrypted by ANNABELLE free of charge (download link). Note, however, that even if ANNABELLE was not decryptable, you should never submit payments to these criminals. Developers of ransomware-type viruses often ignore victims, once the payments are submitted. Paying typically gives no positive result and users are simply scammed. Never trust these people. If your computer has been infected with an undecryptable ransomware, the only solution is to restore everything from a backup.

Although ANNABELLE is somewhat more complex than a regular ransomware-type virus (as mentioned above, it also corrupts the system, rather than simply encrypting data), it shares many similarities with Cypher, Russenger, THANATOS, and dozens of other ransomware infections. Although these viruses are developed by different cyber criminals, all have identical behavior - they encrypt data and make ransom demands. This type of malware typically has just two major differences: 1) size of ransom, and; 2) type of cryptography used. Unfortunately, most of these viruses use RSA, AES, and other similar algorithms that generate unique decryption keys. Therefore, unless the malware is still in development or has certain bugs/flaws (the key is hard-coded, stored locally or similar), file decryption without involvement of developers (contacting these people is not recommended) is impossible. Ransomware-type viruses present a strong case for maintaining regular data backups, however, note that backup files must be stored on a remote server or unplugged external storage. If not, the malware encrypts them as well.

To eliminate ANNABELLE virus our malware researchers recommend scanning your computer with Spyhunter.
How to protect yourself from ransomware infections?
The key to computer safety is caution. Therefore, pay close attention when browsing the Internet. Never open any file received from suspicious/unrecognizable email addresses. These emails should be deleted immediately, without reading. It is also recommended that you download your applications from official sources only using a direct download link. Third party downloaders/installers are often used to proliferate rogue apps. Therefore, these tools should not be used. Furthermore, keep installed applications up-to-date and use a legitimate anti-virus/anti-spyware suite, however, it is important to remember that criminals proliferate ransomware via fake updaters. Therefore, apps should be updated using implemented functions or tools provided by the official developer.

What happened to my files?
All your files are encrypted and secured with a strong key. There is no way to get them back without your personal key.
How can I get my personal key?
Well you need to pay for it. You need to visit one of the special site below & then you need to enter your personal ID (you find it on the top) & buy it. Actually it costs exactly 0.1 Bitcoins.
What is going to happen if i'm not going to pay?
If you are not going to pay, then the countdown will easily ran out an then your system will be broken.
