GUNRA Virus Ransomware (.ENCRT Files) Decrypt & Removal

The Gunra virus falls within the ransomware type of malicious agent. Ransomware of such sort encrypts all the data on your computer (images, documents, excel sheets, music, videos, etc) and adds its specific extension to every file, creating the R3ADM3.txt text files in each folder containing encrypted files.

Gunra virus: what is known so far?

Gunra adds its extra .ENCRT extension to the title of every encrypted file. For instance, an image named “photo.jpg” will be renamed to “photo.jpg.ENCRT”. In the same manner, the Excel file named “table.xlsx” will be changed to “table.xlsx.ENCRT”, and so on.

In every folder that contains the encoded files, a R3ADM3.txt text file will appear. It is a ransom money note. It contains information about the ways of paying the ransom and some other remarks. The ransom note usually contains instructions on how to purchase the decryption tool from the Gunra developers. That is how they do it.

How did my computer get infected with Gunra ransomware?

There are plenty of possible ways of ransomware injection.

Nowadays, there are three most exploited methods for tamperers to have the Gunra virus planted in your digital environment. These are email spam, Trojan injection and peer networks.

  • Another thing the hackers might try is a Trojan horse scheme. A Trojan is a program that infiltrates into your computer disguised as something else. For instance, you download an installer for some program you need or an update for some software. However, what is unboxed turns out to be a harmful agent that encrypts your data. Since the update package 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 trust the software developers’ official websites.
  • As for the peer file transfer protocols like torrent trackers 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. So you’d better be using trustworthy resources. Also, it is a good idea to scan the folder containing the downloaded objects with the antivirus as soon as the downloading is finished.

How to remove ransomware?

It is crucial to note that besides encrypting your data, the Gunra virus will most likely deploy Vidar Stealer on your machine to seize your credentials to different accounts (including cryptocurrency wallets). The mentioned spyware can extract your credentials from your browser’s auto-filling cardfile.

How to avoid ransomware attack?

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

You can defend your computer from ransomware attack taking three easy steps:

  • Ignore any letters from unknown mailboxes with strange addresses, or with content that has nothing to do with something you are expecting (how can you win in a lottery without even taking part in it?). If the email subject is likely something you are waiting for, scrutinize all elements of the suspicious email with caution. A fake email will surely have mistakes.
  • Never use cracked or unknown programs. Trojans are often shared as a part of cracked software, most likely under the guise of “patch” to prevent the license check. Understandably, dubious programs are very hard to tell from trustworthy software, as trojans may also have the functionality you need. Try to find information on this program on the anti-malware forums, but the best solution is not to use such software.

Frequently Asked Questions

🤔 How can I open “.ENCRT” files?Can I somehow access “.ENCRT” files?

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

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

Hopefully, you have made a copy of those important files. In case you haven’t, there is still a chance that you do have a Restore Point from some time ago to roll back the whole system to the moment when it had no virus yet, but already had your files. All other solutions require time.

🤔 What to do if the Gunra malware has blocked my PC and I can’t get the activation key.

🤔 What can I do right now?

Some of the blocked files can be found elsewhere.

  • If you sent or received your critical files by email, you could still download them from your online mail server.
  • You might have shared images or videos with your friends or relatives. Simply ask them to post those pictures back to you.
  • If you have initially got any of your files from the Web, you can try to do it again.
  • Your messengers, social media pages, and cloud drives might have all those files too.
  • Maybe you still have the needed files on your old computer, a notebook, phone, memory stick, etc.

USEFUL TIP: You can employ data recovery utilities1 to get your lost data back since ransomware encodes the copies of your files, deleting the authentic ones. In the video below, you can see how to recover your files with PhotoRec, but remember: you won’t be able to do it before you eradicate the ransomware itself with an anti-malware program.
