The web space is full of harmful threats, but not many of them can be as problematic as a Ransomware infection like .Onyon Virus Ransomware. This type of malware targets the users’ data and keeps it hostage for a ransom thanks to a secret encryption algorithm. Hundreds of people, who surprisingly found their files inaccessible have recently reported the infection and called our “How to remove” team for help, that’s why this entire page is dedicated to .Onyon Virus Ransomware and all the possible methods to counteract it. One of them is the free removal guide below, which may help you remove .Onyon Virus Ransomware and eventually regain the access to some of your files without paying a penny in ransom. So, if you are looking for an alternative, that doesn’t cost you a fortune, check out the information that follows and carefully decide which course of action is best for you.

Stay away from spam, shady emails, and sketchy content if you don’t want to catch .Onyon Virus Ransomware!

Ransomware threats like .Onyon Virus Ransomware can be very cunning and can infect you without you even having a clue about it. They are usually very intelligently developed with the sole idea to sneak inside the system unnoticed and to secretly apply a malicious encryption to all the files, which the users store on their computer’s hard drives. Anyone may get infected mostly through clicking on infected transmitters such as spam messages, emails with infected attachments, compromised web pages, ads, pop-ups, misleading links, legitimate looking files such as PDFs, word documents or images and even .exe files and shady installers. In most of the cases, a Trojan horse or an exploit kit is used to deliver .Onyon Virus Ransomware through some system vulnerability.

When .Onyon Virus Ransomware infects you, a blackmail scheme comes into play!

There may be no visible signs that your machine has been infected with Ransomware, however, the moment the malware gets inside, it will immediately start to infiltrate your hard drives for certain file types. Normally, the targeted data includes the most commonly used file types such as documents, images, music, video, games, projects, etc. The moment .Onyon Virus Ransomware detects such files, it instantly applies a complex encryption algorithm, which locks them out and makes them inaccessible. Sometimes, the file extension may also be changed with some unfamiliar one, just to ensure that you cannot open or use your files with any program. The idea behind all these actions is to keep the files hostage until you pay a fat amount of money to the hackers, who control the Ransomware. This is literally a blackmail scheme, which threatens you to never access your information unless you fulfill the demands of the criminals. And they clearly inform you about them by placing a ransom note on your screen. If you pay, the hackers promise to send you a special decryption key, which in theory can reverse the encryption and bring all the files back to normal. In practice, however, this is a criminal “business” model which only aims to benefit the hackers without giving you any guarantee for the complete restoration of your encrypted data. That’s why, if you are a victim of a Ransomware attack, the smartest thing you can do is to inform yourself about all the possible options to deal with the infection and counteract it without sponsoring such criminal practices.

What are the possible courses of action?

If we have to be honest, there is not much that can be done in a case of a Ransomware attack. The first thing that probably comes to your mind is to pay the ransom with the hope to save your data. However, paying the required money (which may sometimes reach up to a couple of thousands!) doesn’t necessary mean that the hackers will send you the promised decryption key. There is a greater chance that they will disappear once they get what they want rather than deal with you and your files. Even if they send you a code or some decryption solution, what is the guarantee that it will work properly and it is not some other nasty infection? Trusting the same people who ruthlessly blackmail you is definitely not the smartest thing you could do.

If you remove .Onyon Virus Ransomware, however, you may still have a small chance to save up some of your data. Indeed, nothing can guarantee a complete recovery from a Ransomware attack of this type, but keeping the malware inside the computer is not a good idea either. By using the instructions in the removal guide below, you may at least be able to detect and remove the threat from your system. Once it is clean, you can safely proceed with your attempts to restore some of your files. It would be the best if you have some external backup copies from a hard drive or a cloud but if you don’t have any, you can also try to extract some data with the file-restoration steps below. If you need further assistance, you can check out our list of free decryptors or contact a specialist of your choice for additional help.
