What is Ransomware? Ransomware is a newcomer in a dangerous ransomware family that is built on the CrySIS Ransomware engine and also includes Ransomware and Ransomware that are the other most recent threats. Finding out about the presence of any of these infections could be a shocker. The truth is that when this ransomware sneaks onto your machine, there will be a big loss unless you are a careful person or you have learnt from other people’s mistake and regularly save a backup copy of your files. Another chance for you to get your files back after this malware encrypts them is to transfer the ransom fee to the cyber criminals behind this attack. However, experience and victim reports show that this may not be a good idea. In fact, in most cases victims do not get anything in return for their money. But, of course, the decision is all yours. If you want to give it a shot, good luck with that. In any case, our malware researchers at suggest that you remove Ransomware if you want to secure your computer. Let us explain our reasons and share some important details with you.test

Where does Ransomware come from?

The most likely way for you to be infected with this nightmarish program is through spam e-mails. Ransomware infections often use Trojans to infiltrate the victims’ operating system silently. This means that these spam mails have an attached file pretending to be something important for you to see but it is indeed a malicious executable file. In certain cases this file itself can be the infection but in other cases it is simply a Trojan that can download the ransomware in the background once initiated. This activation takes place at the moment you try to open the downloaded attachment. You may consider yourself a prudent person who would never open spam e-mails, let alone malicious attachments. However, the spam mails of today can be rather deceiving. First, they can trick the spam filters. Second, they can mislead you, too. For example, such a malicious mail can seem to come from your Internet provider claiming that you have not settled your last invoice. But this spam e-mail can also refer to any bookings you have allegedly made with wrong credit card details or simply a confirmation mail seemingly confirming a flight booking made with your credit card. Do you think you could say no to opening such mails and their attachments?

This is what these criminals count on, too. And, this is how exactly this dangerous threat and all the others as well spread on the web like wildfire. These infections teach us to be very careful about where we click and which mails we should stay away from. Furthermore, we also learn the importance and urgency of having a backup copy of our most important files at least on a removable drive so that we can be saved in such a dire situation. Because even if you remove Ransomware after realizing it has attacked you, it would be too late for you to save your files from encryption.

How does Ransomware work?

This ransomware, similarly to the other family members, uses the RSA-2048 encryption algorithm. This algorithm is, in fact, part of the Windows operating system and therefore it is very fast. It could take as little as 20 seconds for this infection to finish the encryption of all your photos, videos, and documents. So even if you notice that you cannot access or view certain files, or that their names have added a “” ending, it would be too late for you to delete Ransomware. Still, it is the right thing to do since there is no other way to restore your system security.

This ransomware drops a text file ("How to decrypt your files.txt") in every folder where files have been encrypted. This file contains information about the attack and the solution. This information is very similar to what you will see on your screen at the moment the encryption is finished. An image takes over your screen replacing your wallpaper. This is a very plain image containing just a few words really. You are simply told that your files have been encrypted and that you have to send an e-mail to the given address: You are supposed to get more details in a response mail. Seeing this ransom note and realizing that you cannot access your files could intimidate you enough to want to rush to contact these criminals and even pay the demanded fee. This is a natural reaction. But we would like to ask you to try to make the right decision with a clear head. Because what if these crooks do not deliver the essential private key or the decryption software? What if a technical issue emerges and the infection cannot reach the server to get this key? Nevertheless, sooner or later you need to make the move and remove Ransomware from your computer. So let us help you with the necessary steps.

How do I delete Ransomware?

We have included instructions for you to handle this threat manually. Please use our guide only if you are sure you can identify the malicious .exe file and remove it and all other related files and registry entries. If you do not feel up to this task, you should think about installing a decent security tool that could automatically take care of all possible infections and defend your system from future attacks. If you want to protect your computer in the future, it is also important that you do not visit suspicious file-sharing and gaming websites, refrain from clicking on third-party ads, and keep all your drivers and software updated.
