Meka ransomware virus

Ransomware is one of the biggest disaster among the horrifying viruses in the computer world.

Ransomware is a type of malware from cryptovirology that threatens to publish the victim's data or perpetually block access to it unless a ransom is paid. While some simple ransomware may lock the system in a way which is not difficult for a knowledgeable person to reverse, more advanced malware uses a technique called cryptoviral extortion, in which it encrypts the victim's files, making them inaccessible, and demands a ransom payment to decrypt them. In a properly implemented cryptoviral extortion attack, recovering the files without the decryption key is an intractable problem – and difficult to trace digital currencies such as Ukash or Bitcoin and other cryptocurrency are used for the ransoms, making tracing and prosecuting the perpetrators difficult. Ransomware attacks are typically carried out using a Trojan that is disguised as a legitimate file that the user is tricked into downloading or opening when it arrives as an email attachment.

From Wikipedia.

Meka virus is a specifies of DJVU family virus. It is a typical robbery, only without tactile criminals near you: hackers get into your PC and loot all they wish, leaving a user with a crippled system that contains only encoded data. Meka virus is the brightest example of this type of viruses: it is easy to find and too hard to remove, but we can assist you with it. In this item, we want to explain to you the main principles of Meka's work and the ways of its penetration into your PC. We will tell you how you can evade ransomware infection, and what you need to do to decrypt the files. You need to realize that some the ransomware will not ever get beaten, and if you have one – your files may be already gone for good. There is a possibility that swindlers made a mistake to leave the way to uninstall their virus or to reverse the caused harm. The victim can be guarded by specific settings of the computer, and we can tell you how to apply it.

Summary

 

What is Meka ransomware and how it works

The point is that all ransomware utilize the famous encryption algorithms, such as the AES and the RSA. They are simply the very sophisticated ones, and you can't break them. Well, you can break them, having a century of common PC’s working time or a couple of years of operation on the most powerful computer of the Earth. We're certain that neither of the given variants suits you. The easiest way to defeat Meka is to not let it enter the PC, and we will tell you how it could be done.

The encoding malware, also called ransomware, are the viruses that infest customers' computers and spoil their information to gain money for its decryption. The penetration is usually performed through malspam campaigns or 0-day Trojans. E-mail fraud is very easy to recognize – you'll receive it without any notice, and there will be a file in it. If we're talking about zero-day vulnerabilities, it’s a bit harder – you'll never see that it's coming before you get encrypted so that the most efficient method is to frequently download the newest updates for the OS and other tools which you have in it.

Usual ransomware programs aren’t too complicated in their code, yet even the very carelessly made one is highly hazardous, and we will explain our point. It’s all about the encoding algorithms. Ransomware's aim is not to take your files. It only needs to penetrate the OS, encode your information and remove the original data, placing the spoiled files instead of them. You can't use that data if they're encrypted. You cannot use the files and can’t restore them. There are several techniques to recover the files, and they all are written down in our entry.

When the ciphering is finished, ransomware gives you a ransom message, and when it popped up – it's too late. The only measure you can take now - to delete a virus from the computer and try to recover the information. We've said “try” because the odds to handle it not having a decryptor are faint.

Meka removal guide

It’s essential to delete ransomware until you go on as if it remains in the system – it will start encrypting every single file which comes into the PC. Even more - any flash drive you are linking to the infected device will become ciphered as well. To evade that – eliminate the virus by following our effective step-by-step instruction. Remember that the removal won’t recover the data, and after doing it, you will not be able to pay money to fraudsters. It will be smart that since every ransom gained makes fraudsters more confident in their "business" and gives them more budget to develop complex viruses. The important thing is that when you’re dealing with hackers, they won't give you a proof that the information will be restored when they receive the money. They have already decrypted your data, and we don't think that you want to send them your money after that.

When you remove Meka from your system, and you triple-checked it, it’s time to think about the restoration techniques. Firstly, we should notice that the very effective way is to use a backup. In case you have the backups of the information and Meka is fully eliminated – don't fret. Erase the wasted files and upload the copies. In case you have no backups – the odds of getting your files are critically low. Shadow Volume Copies service is your lucky ticket. We're saying about the basic service of Windows, and it duplicates each bit of information that was changed. You might find them via specific recovery utilities.

Unfortunately, all complex ransomware may clear these copies, but if you use an account that has no administrator rights, Meka simply couldn’t perform that not having your permit. You might recall that several minutes prior to the showing of a swindler's note there was another menu, asking to apply alterations to your device. If you've declined these changes – your SVC are still there waiting for you, and you may use them and restore the data with the help of special tools as Recuva or ShadowExplorer. You may simply locate them both in the Net. It's safer for you to load them from the webpages of their creators, with step-by-step instructions.
