How to remove ZyNoXiOn Ransomware and decrypt .ZyNoXiOn files

0
ZyNoXiOn is a file-encrypting virus that leaves significant damage after its penetration. Such programs are categorized as ransomware and restrict access to files by applying strong algorithms. All of the affected data get appended with .ZyNoXiOn extension. This means that a typical file like 1.mp4 will be changed to 1.mp4.ZyNoXiOn and reset its icon. Once the encryption process is done, users are facing the text file named HOW TO DECRYPT FILES.txt that contains ransom information. Unfortunately, in most cases, you cannot decrypt data without the involvement of cybercriminals. This is why extortionists propose paying 0.13 BTC (roughly 900 USD) through the attached link to obtain special keys that will unlock the encrypted files. Once done, you have to contact them via their e-mail to get the promised tools. Luckily, with the help of contemporary tools designed by world-class laboratories, it is possible to delete ZyNoXiOn Ransomware and decrypt the infected data.

How to remove Velar Ransomware and decrypt .Velar files

0
Velar is a type of malware classified as ransomware. Ransomware is a category of malicious software that operates by encrypting data and extorting money from users via ransom techniques. During the encryption process, all files are getting configured and obtain new extensions. For example, the non-infected file called 1.mp4 will be renamed to 1.mp4.Velar and reset its default icon. Thereafter, users are presented with a text file displaying the ransom information. The ransom note is called readme.txt. It claims that your system was infected by ransomware that ciphered a large number of files by using a hybrid encryption scheme. In order to restore the blocked data, extortionists ask you to contact them via one of the e-mails and attach your personal ID that is listed in the note. Unfortunately, the only option to access your files is buying a decryption key held by cybercriminals because none of the third-parties software is able to decrypt the infected data. However, it is not recommended to follow the instructions of frauds and paying a ransom because most people get fooled and the problem remains unsolved as a result.

How to remove SD (Unlock11) Ransomware and decrypt .[unlock11@protonmail.com].enc files

0
If you are no longer able to access your files, then this is because ransomware infected your system. SD (Unlock11) Ransomware is not an exception since it ciphers users' data with RSA + Salsa20 algorithm and adds brand new .[unlock11@protonmail.com].enc extension to each file. As an example, standard 1.mp4 will be renamed to 1.mp4.[unlock11@protonmail.com].enc after the encryption process is done. It is necessary to point out that .enc extension is more generic and has been exploited by several types of ransomware including MOTD, TrueCrypter, and Cryptohasyou. After successful encryption, the program automatically opens a ransom note ReadMeToDecrypte.txt, which contains the details on how to decrypt your data. Some versions of SD replace desktop wallpaper for displaying the ransom information. In both cases, to unlock the affected files, users should reach out to cybercriminals via unlock11@protonmail.com. You are also allowed to attach 3 files (less than 5MB) so that swindlers could prove they can be trusted. After sending a message, you will be presumably required to pay a specific sum to unlock your data. Furthermore, they will give you recommendations on how to protect yourself from further attacks. Unfortunately, there is no other option at this moment to decrypt files configured by SD Ransomware without paying the ransom and getting the private keys.
