Nokoyawa is a stealthy Ransomware infection that asks you to pay a ransom in order to liberate your files from its encryption. When you get infected, Nokoyawa secretly encodes all your most valuable information and generates a ransom-demanding message on the screen.

With this in mind, in the next lines, we will share with you our tested and detailed removal instructions. We will also provide you with some alternatives to the ransom payment, which may assist you to get back your information without giving the criminals your money. So, once you remove the infection, we’ll point you to the guide’s file recovery section, hoping you’ll find it useful. But let’s first say a few words about this new cyber threat before we move on, so you can better understand the malware you’re up against.

Ransomware infections usually happen when web users click on some malicious content. Such content is often distributed through spam emails with infected attachments, misleading messages, harmful links, torrents, and questionable downloads. Sadly, there are no noticeable signs of either the infection, or the file encryption process, so the Ransomware generally runs unnoticed until it shows itself on the victim’s screen through a ransom note.

The Nokoyawa file encryption

The Nokoyawa file encryption is a complex code that can only be reversed with a special decryption key. Unfortunately, the decryption key for the Nokoyawa file encryption is kept with the crooks, and they would send it to you in return for a substantial sum, payable in BitCoins.

They provide specific directions on how to pay the BitCoins within a ransom note displayed on your screen instantly after the encryption of the file has been completed. Very often, the hackers threaten to destroy the decryption key completely if the payment is delayed or not made. Alternatively, they may threaten to double the amount requested for the ransom to make the victims pay quickly. However, you shouldn’t fall for these manipulative tricks, and you should always make sure to give yourself enough time to figure out what course of action would be best in your case.

Leading security experts, including our “How to remove” team, share the opinion that it is not a good idea to send money to the crooks behind Ransomware. For one, many victims burn their money this way only to get a key that doesn’t work, and that is utterly ineffective. Secondly, many users never get a key for decryption at all.

Therefore, we encourage you to try to restore your files through other means and explore some alternatives in the removal guide below. You can recover your information from personal backup copies stored on an external drive or on a cloud, if you have any such backups. That’s why creating regular backups, and keeping them on external storage is the smartest, and simplest way to protect yourself from data loss caused by a Ransomware attack. However, to remove the virus, and prevent future infections, you would still need an adequate antivirus software with specialized anti-ransomware features, as well as a well-maintained, and frequently updated system.
