If Oni Ransomware is the reason for you to reach this page, then you should know that this is a freshly detected Ransomware cryptovirus, which can cause a lot of damage to your PC and your files. Ransomware, basically, is a very harmful type of malware that blocks victims’ access to their computers or the files found inside and requires a ransom payment. Some versions of this threat are more sophisticated and tricky than others. Once they encrypt your files, they may claim that a payment should be made to escape penalty from state authorities (usually the FBI or local agency), while other versions may use different delusive scenarios. The general idea is to make you believe that this is the only way to deal with the encryption and decrypt your data. Some recently detected Ransomware threats may also perform additional activities that can run in the background of the infected computer and may include personal information stealing, booting legitimate software (antivirus, anti-spyware, etc.), system and file deletion and other harmful activities. The first prototypes of this malware have been released in Russia some 20 years ago. Since then, they have appeared almost everywhere in the world and have become probably the most dreadful online threats that one could encounter. If your computer has been infected with Oni Ransomware, we understand your frustration. Indeed, there is hardly anything more malicious than being blocked from assessing your valuable data and being ruthlessly blackmailed to pay ransom to access it again. For this reason, in the next paragraphs, we have prepared a detailed removal guide to some alternative methods of dealing with the infection. Feel free to use them in case you don’t want to pay a ransom.

How Oni Ransomware operates

Oni Ransomware is a new addition to the notorious Ransomware family and as such, you can expect it to show no mercy to your system and your data. Once it finds its way inside the computer, the cryptovirus starts scanning the drives for a list of target file extensions and encrypts all the files that contain them. This way, it makes them inaccessible and ready to be kept hostage in exchange for a ransom. The virus may change the desktop background or display a ransom message in the form of a text file in order to inform the victim of the ransom demands of the hackers. Identical ransom message may be found in any folder containing encrypted files. Normally, the criminals want to remain anonymous that’s why they will prompt you to contact them through a special illegal web page and make a ransom payment in cryptocurrency (usually Bitcoins). If you strictly fulfill all of their instructions, they promise to send you a decryption key.  However, whether they will really send you anything and whether it will work or not, nobody can tell. The only thing that is sure is that you will be risking your money without knowing whether you will be able to save your files or not. For this reason, we encourage you to try all the recovery methods explained below before considering the ransom payment.

How did you infect your computer with this malicious virus?

Although your first thought might probably be “It was not me!”, read this paragraph to the end. Ransomware viruses use the technique of the Trojan horse to hit their target without being recognized as dangerous objects. This means that distributors of infections like Oni Ransomware usually offer the victims to open a web page that looks safe, saying it contains important information that needs to be read. Typically, fraudsters use legitimate-looking emails to deceive the victims, present themselves as employees of well-known and trusted companies and speak illegally on their behalf. Claiming that they have reliable information while in fact, they carry malicious scripts through emailed files titled “Invoice,” “CV / Curriculum,” “Payment,” or “Urgent information” they spread the threats inside links, ads, or attachments. If you open such suspicious emails, you will surely be infected. That’s why you should always check the sender beforehand. If you have any doubts, better don’t click on anything and scan your inbox. Also, avoid software update invitations, sketchy ads, sudden pop-ups, free installers or social media messages that come from suspicious senders and definitely do not open the attachments they may contain!
