Avdn Virus


Avdn

Avdn is a ransomware infection that prevents users from opening or using their digital files and asks them for a ransom. To complete its agenda, Avdn applies encryption to selected files and leaves a ransom notification on the computer’s screen.

The Avdn virus will encrypt your files leaving a -readme.html file behind.

This Avdn virus encrypts user data using AES-256 + RSA-2048, and then requires a ransom of $ 150 to $ 350 or more in BTC to return the files. Avaddon Ransomware is written in C ++ using WinAPI. Designed for Windows 7-10.Ransomware cryptoviruses like this one are very popular tools for extortion that cybercriminals use to raise quick money from their victims through blackmail. Such infections are also particularly effective in remaining hidden in the system while applying their sophisticated encryption to the victim’s data because most security programs typically do not identify them. What’s more, threats like Avdn usually don’t show obvious signs of their actions and even users cannot rely on specific symptoms to detect them.

Most ransomware-based cryptoviruses like Zwer or Nlah are exclusively developed to detect and lock digital data using a sophisticated encryption code that cannot be deciphered without a decryption key. These infections require money to provide the victims with such a key that can potentially undo the applied file-encryption. The hackers who stay behind such malicious programs normally put a .txt file on the computer’s screen after the attack and provide instructions on how to transfer the money to their cryptocurrency account. In the same file, they typically promise to immediately send a decryption key to those who transfer the required amount.

However, it is not the best idea to trust the promises of the same people who have hacked your computer and have encrypted your data. After all, your money is the only thing the crooks are after, and when you send it to them, they are most likely to disappear without sending you any file-recovery solution rather than dealing with you and helping you get back your files.

The Avdn virus

The Avdn virus is a malicious ransomware-based infection which secretly infiltrates computers and applies a complex encryption algorithm to some of the digital files stored there. The main purpose of the Avdn virus is to seek a ransom from the owners for a file-decrypting key.

The most impacted users of the ransomware’s attack are those who keep very sensitive data on their computers. They may not be able to access the encrypted information in any way and, what is worse, they may never get it back, regardless of how carefully they fulfill the ransom demands of the hackers. Sadly, even if the cryptovirus is removed from the system, some of the files may still remain inaccessible for good. Nonetheless, those people who maintain copies of their files on external hard drives, cloud storage or other devices can safely recover from the attack of a threat like Avdn without much hassle. They just have to remove the ransomware cryptovirus from the computer and then safely connect the backup sources and transfer their files. When a file-backup source is not available, however, and the encrypted files are of great importance, it is best for the victims to explore all the alternative solutions in order to cope with the ransomware in the best possible way. Luckily, there are some options that may not involve paying ransom to anonymous hackers and we have listed them in a special section of the removal guide which you can find below.

The Avdn file decryption

The Avdn file decryption is a file-recovery process that is supposed to return the information encrypted by the ransomware to its previous state. The Avdn file decryption process needs a special encryption key to get activated, which key can only be obtained after you pay a ransom for it.

Our suggestion, however, is to firstly explore our removal guide and the methods mentioned there and not to rush with a money transfer to some anonymous hackers.
