Nokoyawa File Ransomware Virus Removal

NOKOYAWA is a ransomware infection. It is created by cybercriminals to encrypt users’ files and extort money. It modifies files after encryption by adding the “.NOKOYAWA” extension. For example, a file “myphoto.jpg” will be renamed as  “myphoto.jpg.NOKOYAWA” after encryption. This is an encrypted version of the original file. You cannot access this file without the decryption key. This same process happens to all the files stored on the infected PC.

According to Trend Mciro research, this Nokoyawa Virus is probably a new variant of the Hive Ransomware family. After encrypting files, it also provides a ransom note “NOKOYAWA_readme.txt” that contains instructions for victims. It asks users to contact attackers and pay ransom money to buy decryption software. Read this guide to know how to remove this virus and restore your files.

What is Nokoyawa Virus?

Nokoyawa is an extremely harmful computer malware that belongs to the file-encrypting family. It can easily intrude on your PC without your consent or permission. Once inside, it will encrypt all your important and personal files without your knowledge and render them inaccessible. It will also mark its signature by adding its own extension to the end of the file names.

Nokoyawa will also leave a ransom note on your computer to notify you about the encryption. It will ask that your files, videos, audios, etc. are encrypted and can only be opened by private decryption keys. It will demand a huge sum of amount through cryptocurrency to give you that decryption key. In case you don’t pay the ransom money, it threatens to delete all your files permanently.

How it infects your PC?

Nokoyawa is able to attack all types of Windows PC. It uses various lucrative methods to intrude on your machine. Spam email attachments are one of the most used methods. Attackers send emails containing malicious files with catchy titles to thousands of people. Most people open such emails and download the attachments. Ransomware instantly infected their PC and further spread through public Wi-Fi and shared network connections.

Nokoyawa Virus can also get distributed through bundled freeware programs, cracked software, porn sites, torrent files, and p2p file sharing. It is very common that users disable their anti-virus to install such programs. After successful intrusion, it also disables your anti-virus and firewall security. Due to this, you will not be able to remove this infection using your regular security software.

Do not pay ransom money

If you are thinking all your files will be recovered after you make the payment? Not exactly. Most of the times victims don’t get the decryption key. If somehow you will get the decryptor, Nokoyawa virus will still be on your system. It will stay hidden until it encrypts your files again with any new variant. It is also possible that the decryption key may bring more threats and viruses to your PC.

Sometimes files get corrupted after encryption and decryption will not work. There are a number of scenarios in which Nokoyawa can make further damage to your PC even after taking your money. So it is really not a good idea to pay money. You cannot track the cryptocurrency payment, so you will never find the person who got the money.

We strongly suggest that ransomware victims try to delete the virus from their system ASAP. If you remove this virus, it will not be able to do any further damage to your computer. You can easily recover your files through backup. If you don’t have a backup, you can try data recovery software or wait for free decryptor software to be released.

Ransom note “NOKOYAWA_readme.txt” contains the following message:

Be sure, you can't restore it without our help.
