Seto Virus


This page aims to help you remove the Seto Virus for free. Our instructions also cover how any .Seto file can be recovered.


.Seto is the newest of the STOP DJVU ransomware strain that changes every few days recently. .Seto is not different in any way relative to other variants like .Gero and .Hese. The only feature that slightly changes with .Seto is the ransomware note displayed to victims.

Seto Virus

.Seto’s ransom note sometimes changes with users. See the other one below for reference.

Seto is the name of a new Ransomware infection, which has been created with the sole purpose of making money for its authors. Security experts are warning that this infection is spreading mostly through attachments in spam emails, different ads, eye-catching offers, links and compromised web pages, but you can get infected in many other ways as well. Immediately after you interact with the transmitter, the malicious software sneaks in the system without being noticed and starts to scan the device for video and audio files, images, documents, databases, and other personal files which it may be important to the victim. Then it silently encrypts them using a complex file-encrypting algorithm. A change in the file extension’s name may also be added to the affected files. Seto also leaves a ransom message on the infected computer, which explains to the user that the latter must pay a certain amount of money (usually requested in bitcoins) to regain the access to his information again.

The message from the authors of the Ransomware provides more specific information to the victims about what has happened to their computer and their data, and about how they must pay the money in order to retrieve their files. The Cyber criminals want the users to pay as soon as possible and typically give them a short deadline for that. Those who agree to strictly fulfill all the hacker’s demands are promised to receive a special decryption key with the help of which they can decrypt their sealed data.

The .Seto file extension

The .Seto file extension appears at the end of files, like a normal file extension. Unlike normal extensions, however, the . Seto file extension is added after the NORMAL extension, giving files a “double” extension. This signifies a ransomware encryption.

Encrypted with .seto files

This may sound like the quickest solution, however, it’s not a good idea to trust the cyber criminals. For one, there is no guarantee that they will really send the key that they’ve promised to you. And secondly, nobody can tell you if that key will really manage to effectively decrypt the applied encryption.

That’s why, instead of risking your money, what most security experts, including our “How to remove” team, recommend is to explore other methods of dealing with Ransomware such as Gero, Hese . Your focus should be on removing Seto and cleaning your system, because, with an active infection in there, you may not be able to use the computer for anything and all the files you create may get encrypted.

The Seto virus

Once the Seto virus appears in your system, fast signs it encrypts your data can be see by the sluggishness if your PC. The Seto virus encrypts files one by one, so if you see them fast, we recommend shutting down the machine immediately before it is fully infected.

The Seto Virus will leave a _readme.txt file with instructions for you to follow

To get rid of Seto effectively, you are advised to use a trusted anti-malware tool. Such software will guarantee you the correct removal of the Ransomware and will also provide you with protection from similar viruses in the future. To scan your system properly and remove all malicious components, make sure you have updated the software to the latest version before you start scanning.

Manual removal of Seto is also possible but inexperienced computer users may find that difficult. Yet, you may still want to check the instructions given under the article and give a try to some of the suggestions in the file-recovery section. Keep in mind, though, that some Ransomware-based threats may try to delete the Shadow Volume Copies of the encrypted information in order to prevent the victims from recovering it. In this case, the best way to get back your data is to copy it from external backups, if you keep any.

The Seto Ransomware in action

Once the Seto ransomware is done with the encryption and drops its ransom note it goes dormant – but it doesn’t disappear. The Seto ransomware can re-encrypt your files later on if you don’t delete its core files.
