There are many malicious computer programs. Every day their number increases, they become more professional and dangerous. Not all antiviruses are able to fight them. Recently, such a problem has become popular when the virus encrypted files in XTBL. The user does not have access to personal information.
What to do in this case? Unfortunately, many users make common mistakes, as a result of which they do not fix the problem, but make it more widespread. Therefore, you need to consider in detail the instructions for action.
What does a virus do on a computer?
Every malicious program comes in a certain way. But the principles of their action are approximately the same. First, they are downloaded to a computer via the Internet, removable storage media, or in some other way.

All these steps will not help eliminate encryption, but they will slow down the process. You can also send the original malware file to antivirus developers. Then the process of protecting against such a trojan will go faster.What you do not need to do?
When a serious virus has encrypted CBF files, either a fresh anti-virus program or a qualified specialist can decrypt them. There are such actions, which in no case should be practiced by users:
- Treat or eliminate malware automatically or on your own. Removing the source of the problem will not help deal with it.
- Reinstall the OS.
- Use decoders recommended for solving similar problems with other trojans (they all differ significantly in codes).
- Use the decoders yourself, without having the skills to select them, or without first obtaining the advice of professionals.
- Clear temporary files, browser history or delete files that are not necessary (the virus can change their location, not just their names, as a result, important information is lost for the user).
- Change properties of encrypted files.
By the way, these rules should be followed if any other encryption virus was downloaded to the computer.Troubleshooting options and consequences

In the second case, you need to hire programmers who, using the available utilities and developments, will try to return the encrypted information. The method is effective, but costly temporarily and financially.You can also use one of the proposed programs, but there is no guarantee that it will work.
Decryption program
Best of all, decryption of files encrypted with a virus is possible for specialized programs. An excellent utility is VectorDecode. You can download it on the official website.
Users note several advantages of the program in question:
- Low cost.
- Convenience and ease of use. Even an inexperienced user can cope with the interface and settings.
- Works with many encrypted files, including CBF, VAULT, and XTBL. Quickly recovers information, opening up user access to personal data.
- Written by a group of programmers who sought to create a universal weapon against cryptographic viruses.
Thus, by means of a small program for which you have to pay (it is not in the public domain), the consequences of the virus can be eliminated.User Tasks
After the virus-pad virus has encrypted the files, users have two main tasks. First, he needs to save the information. Any program that deals with encryption does not work instantly. She needs time. Therefore, the sooner a virus is detected, the less harm it will cause. If the user does not know how to complete the process in the dispatcher, then he needs to turn off the equipment. When a technique does not work, viruses on it are also not capable of action.
Secondly, you need to save all the hacking data so that you can study them. It is highly likely that the attack was carried out by a virus that is already known to programmers and antivirus developers. But there is a chance that it is new. And then only hacking data will help you write a program to fix the problem. To do this, you do not need to turn on the computer after turning off the power or delete any files from its hard drives.
The main thing is not to panic if the system has been attacked. The problem is complex, but it can be fixed. It is important not to start the situation, and not to try to solve it yourself if there are no relevant skills.Varieties of cryptographers
There are several malware that are commonly classified as ransomware:
- Trojan-Ransom.Win32.Rector. This worm usually asks to send SMS. Money is withdrawn from the subscriber’s account. The consequences of its activities are eliminated by the utility RectorDecryptor.
- Trojan-Ransom.Win32.Xorist. The virus displays a window on the monitor where it requires sending the code by mail, after which it sends instructions with further actions. Consequences are resolved using XoristDecryptor.
If the virus encrypted the DOC XLS files, you can try to find the decryptor by the name of the malware. By the way, recently such useful programs are released by Dr.Web (naturally, the licensed version).Conclusion
