Cryptxxx Ransomware Removal Guide

Cryptxxx Ransomware is a malicious program that enters user’s system without permission. It might be that you have already encountered malware with the same title as there were older versions of it. However, in this article, we will focus on the recently released Cryptxxx Ransomware’s variant. Our researchers say that it not only encrypts user’s data but also, it may lock your screen. If the malware managed to enter your system, you should remember when was the last time you made any copies of your files, because there is not much you can do about them. The cyber criminals that created this infection demand a ransom and promises to return your files to the way they were, but there are no guarantees. If you have copies of the most valuable data, we advise you not to waste any money and delete the ransomware from your computer. The removal instructions are available below the text, but firstly you should read some more and learn how to avoid such threats in the future.

Unlike similar infections, Cryptxxx Ransomware does not spread with malicious executable files that usually travel with email attachments. Our specialists learned that the newest variant entered computers while using the Angler Exploit Kit, which can detect vulnerabilities in your system’s security and use them to drop malware. This Angler Exploit Kit can be found on harmful web pages. For example, you may have clicked some pop-up that redirected you to a malicious site. Next time, it would be smart to stay away from suspicious pop-ups and websites. Also, you should think about getting an antimalware tool as it could warn you about the malicious software.

For starters, Cryptxxx Ransomware creates a DLL file in a random CLSID folder, but it needs help to launch it. That is why the malware modifies one of the legitimate files on your system, retitles it as svchost.exe and places it in the same CLSID folder. While testing the ransomware, it was noticed that it could wait from 15 to 62 minutes before it starts encrypting your data. Then it locks various documents, video files, photographs, and so on. Such data should have additional extension, so your files should look like the following example: photograph01.jpg.crypt. Naturally, you cannot do anything with the encrypted data as it needs to be decrypted.

After the files are locked, the ransomware should show you a warning message on your screen. We should also mention that at this moment it might lock your screen too, but our researchers say that it may not happen, or it could be unlocked if you press Ctrl+Alt+Del while restarting your computer. The message explains what happened to your files and demands a ransom from you. It must be paid in bitcoins through the malicious program's website. The text also says that the only way to unlock your data is to pay the ransom and obtain your unique key that is essential for decryption. If you have any files that you cannot lose, you could consider paying, but do not forget that you are dealing with cyber criminals, and they do not provide guarantees.

If you decide to get rid of Cryptxxx Ransomware, you could do that either manually or automatically. Since this is a serious threat, we would advise you to use the second option, which requires installation of an antimalware tool. It would delete the infection and other possible threats from your computer. However, if you want to try the manual removal, you should take a look at the instructions provided below this text. We should explain that except the DLL file and the created CLSID folder, all other data that needs to be erased will be named exactly as the personal ID number that is mentioned in the warning message. Also, since the application could lock your screen, you might need to restart your computer in Safe Mode with Networking. Thus, no matter which removal method you choose, you should follow the first part of the removal instructions if your screen is locked. Still, if you need some help with the removal, feel free to leave us a comment below or contact us via social media.
