Mynvhefutrx virus: what is known so far?

Mynvhefutrx is a Snatch family ransomware infection.

Mynvhefutrx will add its own .mynvhefutrx extension to every file’s title. For example, an image named “photo.jpg” will be turned into “photo.jpg.mynvhefutrx”. Likewise, the Excel file named “table.xlsx” will become “table.xlsx.mynvhefutrx”, and so forth.

In each folder containing the encrypted files, a HOW TO RESTORE YOUR MYNVHEFUTRX FILES.TXT text file will be created. It is a ransom money memo. It contains information about the ways of contacting the racketeers and some other remarks. The ransom note usually contains instructions on how to buy the decryption tool from the Mynvhefutrx developers. You can get this decrypting software after contacting, through email. That is how they do it.

How did Mynvhefutrx ransomware end up on my PC?

There are many possible ways of ransomware infiltration.

Nowadays, there are three most exploited methods for malefactors to have the Mynvhefutrx virus acting in your system. These are email spam, Trojan introduction and peer networks.

If you access your inbox and see emails that look just like notifications from utility services providers, postal agencies like FedEx, Internet providers, and whatnot, but whose addresser is strange to you, be wary of opening those emails. They are most likely to have a viral item enclosed in them. Therefore, it is even riskier to download any attachments that come with letters like these.

Another option for ransom hunters is a Trojan virus model. A Trojan is a program that gets into your machine disguised as something legal. Imagine, you download an installer for some program you want or an update for some software. However, what is unpacked reveals itself a harmful agent that compromises your data. As the installation file can have any name and any icon, you’d better be sure that you can trust the resource of the things you’re downloading. The optimal way is to use the software companies’ official websites.

As for the peer networks like BitTorrent or eMule, the danger is that they are even more trust-based than the rest of the Internet. You can never know what you download until you get it. Our suggestion is that you use trustworthy resources. Also, it is reasonable to scan the folder containing the downloaded files with the antivirus as soon as the downloading is complete.

How to remove ransomware?

It is important to note that besides encrypting your files, the Mynvhefutrx virus will probably install Vidar Stealer on your computer to seize your credentials to different accounts (including cryptocurrency wallets). That spyware can extract your credentials from your browser’s auto-filling cardfile.

Often criminals would decrypt some of your files so you know that they really have the decryption program. Since Mynvhefutrx virus is a relatively new ransomware, anti-malware engineers have not yet found a way to undo its work. However, the anti-ransomware instruments are constantly updated, so the effective countermeasure may soon be available.

Of course, if the criminals succeed in encrypting victim’s critical files, the desperate person will probably fulfill their demands. However, paying a ransom gives no guarantee that you’re getting your data back. It is still risky. After obtaining the ransom, the racketeers may deliver a wrong decryption key to the victim. There were reports of ransomware developers simply vanishing after getting the ransom without even writing back.

The best safety measure against ransomware is to have aan OS restore point or the copies of your critical files in the cloud drive or at least on an external drive. Obviously, that might be insufficient. The most important thing could be that file you were working upon when it all happened. Nevertheless, it is something. It is also reasonable to scan your PC for viruses with the antivirus program after the system restoration.

There are other ransomware products, besides Mynvhefutrx, that work similarly. For instance, Gaqq, Wayn, Agvv, and some others. The two main differences between them and the Mynvhefutrx are the ransom amount and the method of encryption. The rest is almost identical: files become encoded, their extensions changed, ransom notes are created in every directory containing encrypted files.

Some lucky victims were able to decode the blocked files with the help of the free tools provided by anti-malware developers. Sometimes the criminals accidentally send the decryption key to the wronged in the ransom readme. Such an epic fail allows the user to restore the files. But of course, one should never expect such a chance. Make no mistake, ransomware is a criminals’ instrument to pull the money out of their victims.

How сan I avoid ransomware infiltration?

Mynvhefutrx ransomware doesn’t have a endless power, neither does any similar malware.

You can protect your PC from ransomware injection taking three easy steps:

  • Ignore any emails from unknown mailboxes with unknown addresses, or with content that has likely no connection to something you are waiting for (can you win in a lottery without participating in it?). In case the email subject is more or less something you are waiting for, scrutinize all elements of the suspicious letter carefully. A hoax email will surely contain mistakes.
  • Never use cracked or untrusted software. Trojans are often distributed as an element of cracked software, most likely as a “patch” which prevents the license check. Understandably, dubious programs are difficult to tell from trustworthy software, because trojans may also have the functionality you need. Try searching for information on this program on the anti-malware forums, but the best way is not to use such programs at all.
  • And finally, to be sure about the safety of the objects you downloaded, use GridinSoft Anti-Malware. This software will be a perfect armor for your PC.


🤔 How can I open “.mynvhefutrx” files?Are the “.mynvhefutrx” files accessible?

There’s no way to do it, unless the files “.mynvhefutrx” files are decrypted.

🤔 I really need to decrypt those “.mynvhefutrx” files ASAP. How can I do that?

It’s good if you have fаr-sightedly saved copies of these important files elsewhere. If not, there is still a function of System Restore but it needs a Restore Point to be previously saved. All other solutions require time.

🤔 If GridinSoft deletes the Mynvhefutrx malware, will it also delete my files that were encrypted?

No way! Your encrypted files are no threat to your PC.

GridinSoft Anti-Malware only deals with actual viruses. The virus that has infected your PC is probably still functional and it scans your system from time to time to encrypt any new files you might create on your computer after the infection. As it has been mentioned above, the Mynvhefutrx virus comes with the company. It installs backdoors and keyloggers that can take your account passwords by trespass and provide criminals with easy access to your computer in the future.

🤔 What to do if the Mynvhefutrx ransomware has blocked my computer and I can’t get the activation code.

If that happened, you need to have a memory stick with a pre-installed Trojan Killer. Use Safe Mode to do the cleaning. You see, the ransomware starts automatically as the system launches and encrypts any new files created or imported into your system. To stop this function – use Safe Mode, which allows only the essential programs to run upon system start. Consider reading our manual on running Windows in Safe Mode.

🤔 And what should I do now?

Some of the blocked data can be located elsewhere.

  • If you sent or received your important files via email, you could still download them from your online mailbox.
  • You may have shared images or videos with your friends or relatives. Simply ask them to post those pictures back to you.
  • If you have initially downloaded any of your files from the Internet, you can try doing it again.
  • Your messengers, social media pages, and cloud storage might have all those files too.
  • Maybe you still have the needed files on your old PC, a portable device, cellphone, external storage, etc.

HINT: You can employ file recovery utilities2 to retrieve your lost information since ransomware encodes the copies of your files, deleting the authentic ones. In the tutorial below, you can learn how to use PhotoRec for such a restoration, but be advised: you can do it only after you kill the ransomware itself with an antivirus program.
