What is Ransomware?

If your computer is under attack by Ransomware, you can say goodbye to all your important files unless you have made regular backups on removable media. This infection proves again that your files are not safe on your computer if it is not protected by a decent up-to-date anti-malware application. This ransomware encrypts your files and demands a certain amount in return for the recovery of your files. But how can you believe these cyber criminals that they will actually send you the decryption key after you pay the ransom? If you want to save your system, you should not hesitate to remove Ransomware. Keep in mind that this will not recover your files but at least your computer will be clean again and safe to use.

Where does Ransomware come from?

Just like most of the ransomware infections coming from the same family, including Ransomware, Green_ray Ransomware, and Ransomware, this program is also spread via malicious attachments in spam e-mails. Many users believe that just because they have a spam filter, they are all protected against these beasts. We hate to burst your pink bubble but the truth is that certain spam e-mails can actually evade spam filters by tricking them. These deceiving mails may use fake sender addresses, such as legitimate company names, and intriguing subject matters to raise the eyebrow of their victims. Such subjects may include credit card errors, problems with bookings (hotel and flight), overdue invoices, and the like. Even if you think that “this cannot be real” when seeing such a mail in your inbox, it is quite likely that your curiosity will convince you to open it and check the attached document, which is indeed the malicious executable file that activates this ransomware.

Many users believe that such threats just appear on their systems “magically” out of nowhere whereas these infections are due to a few mistaken clicks of their own. In this case, in fact, you need to click at least three times to infect your machine with Ransomware. First, you open the spam mail. Second, you download the attached file. And, finally, you try to open this malicious file. We hope that you see now the responsibility you have to be more careful with your clicks when you use your computer. One click less and you could be saved and not infected. But, if you are eager to see the fake invoice or whatever document these crooks claim to have attached, you will be doomed and your files will be lost forever if you cannot recover them by using your backup copy. If you do not remove Ransomware, there is a good chance that it will restart with your Windows and encrypt all your new files again and again.

How does Ransomware work?

According to our malware researchers at, this vicious program is built on the CrySIS Ransomware engine. It uses the RSA-2048 built-in Windows algorithm to encrypt your files, including your text files, pictures, videos, and program files. The affected files get a “.id-B4500913.{}.xtbl” extension that could be a giveaway that your system has been attacked by Ransomware; however, you may not be quick enough to realize this because your desktop background is replaced after a very short time you activate this infection. The ransom note is very simple this time: It only gives you an e-mail address ( to contact if you want to see your files again. We do not recommend that you establish any kind of connection with these criminals because it never really ends well. In fact, there is very little chance that you get what you want, i.e., the private key that could decrypt your kidnapped files. It is possible that you are asked to pay hundreds of US dollars worth of Bitcoins in order to get this private key, but you may not get anything other than a brain-freeze when you realize that after losing all your files, now you may lose your money, too. If you want to restore order on your computer, you should remove Ransomware right away. This is what you need to do when you do have a backup, too, since you should not start copying your files back until your PC is totally clean.
