What kind of malware is One Ransomware and what damage can it cause?

One Ransomware is a Ransomware-based program, which has been developed by cyber criminals for the purpose of file encryption and online blackmail. Basically, Ransomware is at present among the fastest developing malware in the world, and One Ransomware is one of its latest and most sophisticated versions – a data-locking cryptoviurs, which is capable of invading your system without any visible symptoms. It can infiltrate all of your drives, detect the files that you are using the most, such as images, videos, games, documents, work files and projects, music, etc. and encrypt them one by one with a very complex data-encrypting algorithm. In fact, what makes this malware really dangerous is the secret encryption it uses, which serves to prevent you from accessing all of your encrypted files. They become locked and you are not able to open or use any of them unless you apply a special decryption key. That key is in the hands of the criminal hackers, who stand behind the threat, and once the dirty job of the Ransomware is completed, they come into play. The criminals place a ransom note on your screen and ask you to pay ransom in exchange for the decryption key if you want to regain the access to your files.

How can Ransomware infect you?

Threats like One Ransomware could be found almost anywhere on the web. It is very hard to detect them since they use very tricky methods of infection and camouflage. In most of the cases, Ransomware comes inside your computer with the help of a Trojan horse. Basically, the Trojan provides enough system vulnerabilities for any malware to sneak in, so a threat like One Ransomware can easily exploit that and silently enter your system. But, you can also get infected if you happen to click on some well-masked malware transmitter such as spam, a malicious email attachment, fake ad, misleading link, a compromised software installer or an infected webpage. Unfortunately, you may not see any visible symptoms, which may indicate the infection on time, and you will most probably come to know about it only after the ransom note appears on your screen.

How can you deal with One Ransomware?

A Ransomware infection is really difficult to handle. The victims may need the help of an expert or very powerful antivirus software to detect the threat. That, however, may be a very costly solution, which still may not provide a complete recovery from the attack. Even paying the ransom may not guarantee that you will really decrypt the encrypted files. With such complex encryptions, it often happens that the decryption key fails to restore your files. Unfortunately, you may not even get the key, because most of the times, as typical crooks, the hackers vanish the moment they receive your payment. That’s why, in case of a Ransomware attack, it is best if you seek other options to recover your system and files.

An alternative could be the removal guide below. It contains very detailed instructions that can help you locate the infection and manually delete it from your system. Of course, you have to be very careful and strictly follow the steps so you won’t make a mistake. This will remove One Ransomware from your system, but we have to be honest here – it may not recover your encrypted files. For that, you can try the data-restoration instructions, or you can get your files back from some copies on an external drive or a cloud if you keep any. Unfortunately, no one can provide you with full data recovery from such a nasty Ransomware attack. However, trying everything possible to minimize the loss is still preferable to making the unscrupulous hackers rich.
