Ytbn ransomware – an infection that locks files and demands a ransom in cryptocurrency to regain access to them

Ytbn ransomware is malicious computer software that is developed to attack Windows computers around the world. As soon as this infection finds its way to your device, it encrypts all personal files and renames them by appending a .ytbn extension to their original filenames. Afterward, a ransom note named _readme.txt is generated and placed directly on the desktop so you could find it with ease.
Within it, developers of Ytbn ransomware virus declare their demands and instructions. They provide two emails (helpteam@mail.ch, helpmanager@airmail.cc) that their victims must use to establish contact within 72 hours to receive a 50% discount on the ransom amount. That would lower the price from $980 to $490.
Although that might seem like the easiest way out of this sticky situation, no ransomware victims should ever succumb to their assailant's demands, which only encourages them to attack more people and expand their dirty empire. By reading this article, you'll find out how to remove Ytbn virus, restore corrupted system directories, and evade such severe infections in the future.
The article's culprit derives from the Djvu ransomware family. Since it was first detected in late 2018, it has been spewing out new versions each week. Because of that, companies such as Emsisoft are doing their best to create free decryption tools that could help ransomware victims get out of this predicament scotch-free. If they don't work in your case, there still might be better ways to regain access to your files than paying off the perpetrators.

When ransomware infects your Windows computer, it will encrypt archives, backups, music, videos, documents, and all other personal data. According to the assailants, the only way to restore them is by using their decryption key or software. But that might not be entirely true. We've compiled a list of software that could help with .ytbn file recovery. All of them are posted at the bottom of this article.
As stated before, Ytbn file virus belongs to the Djvu ransomware family. Although its ransom note is written in English, it can infect computers in any country. This family is one of the most productive as it releases new variations each week or even more frequently. Here's a list of the latest ones:
All of them bear a lot of similarities. All the latest ransomware is appending an extension consisting of four alphanumeric characters. Their ransom notes are almost identical, as well as the used encryption algorithm (RSA-2048). And the contact emails rarely change, suggesting that the same group is operating the infections.

Hence, as well as the rest of the family, Ytbn ransomware developers ask to forward them Bitcoins to receive a decryption key or software. The price depends on how quickly the victims contact their assailants. If that's done within 72 hours of the attack, a 50% discount is applied, lowering the price from $980 to $490.
That's just one of the persuasion techniques used by the crooks. They try to convince you that they have the necessary decryptor by providing a link to a video where it can be seen in action and offering free decryption of one file from the infected PC. The whole Ytbn virus ransom note reads:
ATTENTION!
Don't worry, you can return all your files!

The only method of recovering files is to purchase decrypt tool and unique key for you.

Our stance on contacting the criminals or paying the ransom is clear – never do it. There's no guarantee that the sent tool will work or that the perps will even deliver it. You should remove Ytbn ransomware instead. You can do that by downloading free anti-malware tools such as MalwarebytesMalwarebytes, SpyHunterCombo Cleaner, or similar and scanning the entire system. A proper security tool will do the rest.
This computer infection does a lot of damage to your system files and settings by establishing persistence. It corrupts many components, including the host files, Windows Registry, and others. Thus after Ytbn ransomware removal, you should perform system diagnostics with the FortectIntego tool to fix any system inconsistencies so you could enjoy a stable working environment once again.

Torrent sharing platforms are a hotbed of various infections, including ransomware
Trojans, keyloggers, ransomware, and other malware[1] can be spread in a myriad of ways. Cybercriminals use deceptive ads, fake Flash Player updates, spam emails, RDP attacks, and a bunch of other techniques to infect the computers of innocent people around the globe.
Djvu ransomware developers could also use any of those techniques. But the most likely way to catch an infection from this lineage is while using file-sharing platforms, like the most popular torrent sites. This technique requires the least effort and is severely exploited.
Ransomware is usually camouflaged as cracks for the most popular games, pirated commercial software, and alike. So the next time you'll be thinking of getting copyrighted content for free, please think twice, as you could receive much more than you expected.
Simple instructions to safely remove Ytbn virus once and for all
When Ytbn ransomware virus infects your Windows computer, all personal data that was on the device is inaccessible within a couple of minutes, and then a ransom note appears. It makes modifications to the Registry and other core system settings and files so you could open security websites (including 2-spyware.com), launch your anti-malware software, etc.
Thus it may be challenging to delete Ytbn virus. First off, try opening your security tool. If you don't own one, we suggest downloading free apps such as MalwarebytesMalwarebytes or SpyHunterCombo Cleaner. If it fails to load, you will need to reboot your device and start it in Safe Mode with Networking. To make things easier, we've posted a guide below on how to do that.
Once the anti-malware tool is opened, update its virus database with the latest signatures. Then select to perform a full system scan. When it's finished, select to remove Ytbn ransomware and any other suspicious or malicious files/entries that the security software suggests.
Unfortunately, Ytbn ransomware removal isn't finished yet. You must repair corrupted Windows files and restore any changes done to core system settings. If you don't, your device could exhibit all kinds of strange behavior, including BSoDs,[2] freezing, or even infection renewal. Thus cybersecurity specialists[3] highly recommend performing system diagnostics with the time-proven FortectIntego system repair tool to fix all system-related issues.
