We can imagine the stress you must have felt once you’ve read that you have lost access to certain (potentially important) files on your device. The fact that ransomware has sneaked into your computer alone is intimidating, but the ransom-demanding message that MedusaLocker, Leto Virus or Reco Virus has generated may have added even more to the frustration, as it was probably written in a very intimidating manner. Often, in the case of ransomware infections, the cyber criminals pretend to be legal authorities, claiming that you have broken some rule, and that this has resulted in the encryption of your files. To decrypt them, the hackers may claim that you must pay a “fine”. Needless to say, this is a horrific extortion scheme, and the crooks behind it are using various scare-tactics to make you pay.

The removal guide below, however, will show you how to remove MedusaLocker from your PC, and how to recover your encrypted files. But don’t scroll down just yet, as the information provided in the next lines can prove crucial in ensuring that you never get again contaminated with a ransomware cryptovirus of this type.

The MedusaLocker virus

The MedusaLocker virus is programmed to block the access to your data. The MedusaLocker virus does that by encrypting the files with an advanced algorithm.

Over the past few years, the number ransomware variants has risen to numbers we’ve never seen before in this malware category, and there are no signs that this will stop any time soon. We’re not trying to scare you by telling you this, but we believe knowledge is power, and the more you know about the danger that you are faced with, the greater the chance that you will be able to protect yourself from it.

What MedusaLocker does, and how it spreads around the web are the two most important things we will focus our attention on. First of all, like any ransomware, MedusaLocker is a can slip virtually undetected into your device, and it can encode the most frequently used files. Research has shown that malvertising (malicious advertising) is one of the most effective means of distribution for Ransomware. The malvertisements are fake ads that may appear everywhere on the web, but they do not represent an actual product or service. You get compromised directly by the malware attached to them by clicking on them. This is the reason why we advise our readers to refrain from clicking on any suspicious-looking banners, pop-ups, random page-redirects, and tabs that open automatically. Of course, there are other means of distribution as well, so investing in reliable system security is of utmost importance.

The MedusaLocker file decryption

The MedusaLocker  file decryption is a challenging process. The MedusaLocker files are renamed with the “.encrypted” extension and decryption requires a special decryption key, which is in the hands of the hackers.

MedusaLocker Ransomware

Once infected with the MedusaLocker Virus it will silently encrypt all your files with extension .Encrypted.

Once you’ve been infected, the most important question is how to remove the malware, and possibly recover your files. Therefore, in the removal guide below, there is a section with removal steps and another one with some file-recovery suggestions. We encourage you to give them a try first, and only in the case that nothing works should you consider the ransom payment as a possible option. Keep in mind, though, that the people behind this virus are criminals, and there can be no guarantees if you decide to follow their demands.
