Remove Gcahvv ransomware (Virus Removal Guide) - Recovery Instructions Included

Gcahvv ransomware – a cryptovirus that encrypts victims' files and holds them hostage until ransom is paid

Gcahvv ransomwareGcahvv ransomware is a file-locking computer virus that attempts to extort Bitcoins from the infected users

Gcahvv ransomware is a file-locking virus that demands a ransom after it encrypts all victims' personal data. This malware derives from the Snatch ransomware family. The ransomware was first detected in December of 2018. All family members use the same coding algorithm – AES[1]. All of them have crazy names that seem like random sequences of characters (ZybvqxefmhQensvlcbymkMhcadd, etc.). The virus got his name from the appendix that it adds to all encrypted files – .gcahvv.

After the virus is done with the encryption, a ransom note named “HOW TO RESTORE YOUR FILES.TXT” is created and placed in all affected folders. The same goes for Gcahvv virus . In that note, cybercriminals explain that only they can decrypt victim files and that they shouldn't rename or edit the files because that could lead to permanent data loss. To prove that the necessary decryption tool exists, creators of the Gcahvv file virus offer to send them three files for test decryption. They provide two email addresses to establish contact – legalrestore@airmail.cc and legalrestore@tutanota.com. Furthermore, the perpetrators are urging to contact them within 48 hours of the infection, or the users' data might be lost permanently. No details of the ransom size or preferred payment method are included.

As always, we strongly advise against making contact with the cybercriminals and in no way meeting their demands. When Gcahvv virus and other ransomware developers get paid, it motivates them to attack other individuals or companies. As Brett Callow, a threat analyst with Emsisoft, stated to Business Insider[2] – “If the flow of cash stops, the attacks will stop”.

Users should focus on virus elimination and the health of their devices. We suggest using Malwarebytes and SpyHunter 5Combo Cleaner anti-malware software to remove Gcahvv ransomware automatically. These are dedicated apps capable of not only detecting and deleting threats but preventing them from gaining access to your computer too.

After Gcahvv ransomware removal is complete, we're not out of the woods yet. Ransomware is known to make different modifications to the computer system setting and files, which may lead to lags, crashes, and other abnormal behavior. To undo any changes that the virus did, we highly recommend using the ReimageIntego tool.

Gcahvv ransomware virusGcahvv ransomware is a malicious program that originates from Snatch malware strain

Staying safe from ransomware attacks

From pesky adware to the atrocious trojan horses, nowadays, the internet is riddled with all kinds of malware. Different malware is distributed in different ways. The most common methods for ransomware to spread are file-sharing platforms like The Pirate Bay, BitTorrent, etc., and spam emails.

In torrent sites, everyday computer users can find almost anything, from books and music to pirated software and games. Ransomware is surely hidden within some of them. The cybercriminals tend to camouflage their creations as popular game or illegal activation toolkits (popularly known as cracks). So instead of trying to trick everyone, users should support the developers of their desired apps/games by purchasing the products from their official websites/distributors. 

Cybercriminals are trying to outthink their victims by sending spam emails tailored to them. Soon to be victims might receive a legitimately-looking email from their bank or their shipping company (just a few examples of many options), when in reality, it's a spam email with either a hyperlink that will lead to a malicious site which will download a payload file to the device immediately after opening or an infected email attachment, that will spread the infection as soon as it's downloaded. Look for grammatical errors, keep a keen eye for any discrepancies.

Removal instructions for Gcahvv ransomware

As we mentioned in the first paragraph, getting in touch with the criminals and paying the ransom is the worse thing anyone can do. Malware should be deleted immediately after detection.

Bonus: Recover your data

Guide which is presented above is supposed to help you remove Gcahvv from your computer. To recover your encrypted files, we recommend using a detailed guide prepared by 2-spyware.com security experts.

If your files are encrypted by Gcahvv, you can use several methods to restore them:

Using third-party software like Data Recovery Pro

This app might be able to recover your locked files.

  • Download Data Recovery Pro;
  • Follow the steps of Data Recovery Setup and install the program on your computer;
  • Launch it and scan your computer for files encrypted by Gcahvv ransomware;
  • Restore them.

Using Previous Version feature to recover encrypted files

With this Windows OS feature, you might be able to remove .gcahvv extension from infected files

  • Find an encrypted file you need to restore and right-click on it;
  • Select “Properties” and go to “Previous versions” tab;
  • Here, check each of available copies of the file in “Folder versions”. You should select the version you want to recover and click “Restore”.

Last but not least – Shadow Explorer

Your computer saves copies of most of your files – they are called Shadow Copies. If ransomware didn't delete them, you might be able to restore some of your lost data

  • Download Shadow Explorer (http://shadowexplorer.com/);
  • Follow a Shadow Explorer Setup Wizard and install this application on your computer;
  • Launch the program and go through the drop down menu on the top left corner to select the disk of your encrypted data. Check what folders are there;
  • Right-click on the folder you want to restore and select “Export”. You can also select where you want it to be stored.

No decryption tool is available at this moment

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from Gcahvv and other ransomwares, use a reputable anti-spyware, such as ReimageIntego, SpyHunter 5Combo Cleaner or Malwarebytes

Stream videos without limitations, no matter where you are

There are multiple parties that could find out almost anything about you by checking your online activity. While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.

Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful Private Internet Access VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.

Data backups are important – recover your lost files

Ransomware is one of the biggest threats to personal data. Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.

While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as Data Recovery Pro can also be effective and restore at least some of your lost data.
