What is Ransomware? Ransomware can slither onto your operating system without your knowledge even if it is actually you yourself who let it onto your computer and activate it. This dangerous malware program can encrypt all your personal files within one single minute. Ransomware programs are one of the most severe threats you can face in the virtual world since you may easily lose all your stored information and files in a single hit and you would not even see it coming. Since this attack is all about extorting money from you, it is obvious that you will be asked to contact the cyber criminals hiding behind this threat and then transfer the demanded fee to them in exchange for the private key. This key is essential for the recovery of your files and is kept hidden on a secret remote server. The only problem is that if the connection between your machine and this server breaks up, you will never get this private key no matter how fast you pay the ransom fee. This can happen anytime due to technical issues, such as the criminals shutting down the server and going dark. We believe that the best way to protect your computer from further security issues is to remove Ransomware right now. Please read our full report to understand how this dangerous infection can show up on your system and what you can do to safeguard your computer.test

Where does Ransomware come from?

First of all, our malware specialist at have discovered that this threat comes from the same family as Ransomware, Ransomware, Ransomware, and Ransomware, which have all surfaced in the past weeks and months. If you find any of these infections on your computer, you should have no doubt with regard to what your options are. The most usual way to get infected with this threat is to be deceived by a spam e-mail that contains an attached file, such as an image or text document, which you most likely save and open. This is how victims let such a beast on board. We hope that it is clear for you by now how you can avoid similar invasions. It pays to be more careful around your inbox because not all of the mails that end up there are actually clean and legitimate.

Spams can easily mislead you with their subject lines and message, which both point to the urgency of your checking out the attached file. This attachment is a document or photo of an alleged unpaid invoice or problematic credit card details that you would likely want to open. However, once you try to run the downloaded malicious file, apart from opening a fake document you also activate Ransomware. This is an unfortunate step since you will not be able to stop the encryption process even if you delete Ransomware because you just will not have enough time.

How does Ransomware work?

After you run the downloaded executable file, it targets all your images, videos, documents, and program files and encrypts them with the RSA-2048 algorithm. Your files will get an extension typical for the infections in this family (“.id-B4500913.{}.xtbl”) with the only difference being the e-mail address. The “B4500913” string seems to be an ID that can identify certain versions of the family. Our specialists also found that this infection leaves a text file called "Decryption instructions.txt" in all the folders that are affected by the encryption. But apart from that text file, which is indeed the ransom note, an image also comes up on your screen replacing your desktop background to warn you about the unfortunate situation. But this note as well as the text file do not reveal too much about the details. All you learn is that you have to contact these crooks via e-mail (“”) for more information. The most likely scenario is that you have to pay up to a couple of hundreds of dollars in Bitcoins; otherwise, you will not see your files again. But it could be quite risky to give your money to such criminals because they may not keep their promise and send you the decryption key and tool. So if you do not want to lose your money after possibly losing important files and information, you should not hesitate to want to remove Ransomware. Let us tell you how you can do that if you have made up your mind about this malware.
