Xorist-Frozen Ransomware

Xorist-Frozen Ransomware may target personal users as well as data servers. Once this vicious program slithers onto your system, it attacks your personal files and encrypts them in a short time. We have no knowledge of a free decryption tool yet developed by malware hunters. This means that you have but two choices. First, you pay the ransom and risk not getting anything in return while losing thousands of dollars, too. Or, second, you use a backup that you have hopefully saved and stored recently on a portable device. Clearly, we do not advise you to pay at all; it is like supporting cybercrime. Of course, it is all up to you how you decide in the end. We do believe that you should remove Xorist-Frozen Ransomware immediately, though. Please continue reading our full report to learn more about this serious malware infection.

If you find out that this ransomware program has attacked you, it is quite possible that you have recently opened a spam e-mail and viewed its attachment. It is therefore important for you to know that this attachment is indeed the malicious executable even if it appears to be an image or a text document file. Such a spam can be very misleading and deceptive. Even more experienced users may think that it is essential for them to see the content of this mail. Why? Because this spam can pretend to be about an important matter, such as an unpaid invoice, a problematic hotel room booking, or an undeliverable parcel. Such a subject would most likely raise your curiosity even if you know that it cannot be related to you. The problem is that when you open this spam and are instructed to check out the attached file for further information, you will initiate this attack and nothing can save your files then. In other words, you cannot delete Xorist-Frozen Ransomware without the encryption.

You should also keep your browsers and drivers up-to-date because it is possible to get redirected to malicious webpages while surfing the net, where you can trigger malicious scripts to drop such an infection. These pages use Exploit Kits to take advantage of older security holes. It is enough for you to load such a page and you do not even need to engage with content to infect your computer with such a dangerous threat. If you do not want to remove Xorist-Frozen Ransomware or other threats, make sure that all your programs are kept up-to-date.

You can see the extent of the devastation by listing all files with "...Files-Frozen-NEED-TO-MAKE-PAYMENT-FOR-DECRYPTOR-OR-ALL-YOUR-FILES-WILL-BE-PERMANENLTY-DELETED" extension.

The ransom note is stored in a .txt file called "HOW TO DECRYPT FILES.txt", which can be placed on your desktop and in every folders as well where files have been encrypted. This note instructs you to transfer 0.5 Bitcoins, which is about 5,500 US dollars, to a Bitcoin wallet address within 36 hours, or your private key will be deleted. After the transfer, you are supposed to send an e-mail to "" to get a reply with the private key. Unfortunately, there is little or no chance to get this key even if you pay.
