How To Remove BOWD Ransomware (Virus Removal Guide)
Written by: Stelian Pilici
Published on:
If you cannot open your images, documents, or files and they have a .bowd extension, then your computer is infected with the STOP/DJVU ransomware.
This ransomware encrypts the personal documents found on the victim’s computer with the “.bowd” extension, then displays a message which offers to decrypt the data if payment in Bitcoin is made. The instructions are placed on the victim’s desktop in the “_readme.txt” file.

What is the BOWD ransomware?
BOWD is a file-encrypting ransomware infection that restricts access to data (documents, images, videos) by encrypting files with the “.bowd” extension. It then attempts to extort money from victims by asking for “ransom”, in the form of Bitcoin cryptocurrency, in exchange for access to data.
When you are first infected with the BOWD ransomware it will scan your computer for images, videos, and important productivity documents and files such as .doc, .docx, .xls, .pdf. When these files are detected, the ransomware will encrypt them and change their extension to “.bowd”, so that you are no longer able to open them.
Once the BOWD ransomware has encrypted the files on your computer, it will display the “_readme.txt” file that contains the ransom note and instructions on how to contact the authors of this ransomware. The victims of this ransomware will be asked to contact these malware developers via the support@fishmail.top and datarestorehelp@airmail.cc email addresses.
This is the ransom note that the BOWD ransomware will show to its victims:

Here is a summary of the BOWD ransomware:
Ransomware family: STOP/DJVU ransomware
Extensions: .bowd
Ransomware note: _readme.txt
Ransom: From $490 to $980 (in Bitcoins)
Contact: support@fishmail.top and datarestorehelp@airmail.cc emails

File recovery: Unfortunately, it is not currently possible to decrypt the files encrypted by the BOWD ransomware. It may, though, be possible in the future if the decryption keys are recovered from the cybercriminals’ servers. Therefore, if you do not plan on paying the ransom, it is advised that you make an image of the encrypted drives so that you can decrypt them in the future.
How did the BOWD ransomware get on my computer?
The BOWD ransomware is distributed via spam email containing infected attachments, fake software cracks, or by exploiting vulnerabilities in the operating system and installed programs.
Here’s how the BOWD ransomware might get on your computer:
Spam emails: Cybercriminals spam out an email, with forged header information, tricking you into believing that it is from a shipping company like DHL or FedEx. The email tells you that they tried to deliver a package to you, but failed for some reason. Sometimes the emails claim to be notifications of a shipment you have made. Either way, you can’t resist being curious as to what the email is referring to – and open the attached file (or click on a link inside the email). And with that, your computer is infected with the BOWD ransomware.
Be alert for people trying to trick you. Whether it’s your email, phone, messenger, or other applications, always be alert and on guard for someone trying to trick you into clicking on links or replying to messages. Remember that it’s easy to spoof phone numbers, so a familiar name or number doesn’t make messages more trustworthy.
Cracks and keygens: The BOWD ransomware is distributed using fake software cracks or through free programs you download off of the Internet.
Avoid using Peer-to-Peer (P2P) file-sharing programs, keygens, cracks, and other pirated software that can often compromise your data, privacy, or both.
Exploits: The BOWD ransomware was also observed attacking victims by exploiting vulnerabilities in the program installed on the computer or the operating system itself. Commonly exploited software includes the operating system itself, browsers, Microsoft Office, and third-party applications.
Keep your operating system and apps up to date. Whenever an update is released for your device, download and install it right away. These updates often include security fixes, vulnerability patches, and other necessary maintenance.
Remove the BOWD ransomware and recover the files
It’s important to understand that by starting the removal process you risk losing your files, as we cannot guarantee that you will be able to recover them. Your files may be permanently compromised when trying to remove this infection or trying to recover the encrypted documents.
We cannot be held responsible for losing your files or documents during this removal process.
It’s recommended to create a backup image of the encrypted drives or files before proceeding with the malware removal instructions so that you can restore them if the decryption keys are recovered from the cybercriminals’ servers. To create a backup for your encrypted files or drives, you can use EaseUS Todo Backup Free.
This malware removal guide may appear overwhelming due to the number of steps and numerous programs that are being used. We have only written it this way to provide clear, detailed, and easy-to-understand instructions that anyone can use to remove malware for free.
Please perform all the steps in the correct order. If you have any questions or doubts at any point, stop and ask for our assistance.
To remove the BOWD ransomware, follow these steps:

If you are still having problems with your computer after completing these instructions, then please follow one of the steps:
Here are 10 basic security tips to help you avoid malware and protect your device:
Use a good antivirus and keep it up-to-date.
It's essential to use a good quality antivirus and keep it up-to-date to stay ahead of the latest cyber threats. We are huge fans of Malwarebytes Premium and use it on all of our devices, including Windows and Mac computers as well as our mobile devices. Malwarebytes sits beside your traditional antivirus, filling in any gaps in its defenses, and providing extra protection against sneakier security threats.
Keep software and operating systems up-to-date.
Keep your operating system and apps up to date. Whenever an update is released for your device, download and install it right away. These updates often include security fixes, vulnerability patches, and other necessary maintenance.
Be careful when installing programs and apps.
Pay close attention to installation screens and license agreements when installing software. Custom or advanced installation options will often disclose any third-party software that is also being installed. Take great care in every stage of the process and make sure you know what it is you're agreeing to before you click "Next."
Install an ad blocker.
Use a browser-based content blocker, like AdGuard. Content blockers help stop malicious ads, Trojans, phishing, and other undesirable content that an antivirus product alone may not stop.
Be careful what you download.
A top goal of cybercriminals is to trick you into downloading malware—programs or apps that carry malware or try to steal information. This malware can be disguised as an app: anything from a popular game to something that checks traffic or the weather.
Be alert for people trying to trick you.
Whether it's your email, phone, messenger, or other applications, always be alert and on guard for someone trying to trick you into clicking on links or replying to messages. Remember that it's easy to spoof phone numbers, so a familiar name or number doesn't make messages more trustworthy.
Back up your data.
Back up your data frequently and check that your backup data can be restored. You can do this manually on an external HDD/USB stick, or automatically using backup software. This is also the best way to counter ransomware. Never connect the backup drive to a computer if you suspect that the computer is infected with malware.
Choose strong passwords.
Use strong and unique passwords for each of your accounts. Avoid using personal information or easily guessable words in your passwords. Enable two-factor authentication (2FA) on your accounts whenever possible.
Be careful where you click.
Be cautious when clicking on links or downloading attachments from unknown sources. These could potentially contain malware or phishing scams.
Don't use pirated software.
Avoid using Peer-to-Peer (P2P) file-sharing programs, keygens, cracks, and other pirated software that can often compromise your data, privacy, or both.
To avoid potential dangers on the internet, it's important to follow these 10 basic safety rules. By doing so, you can protect yourself from many of the unpleasant surprises that can arise when using the web.
