Dever Virus


Dever is a ransomware virus that encodes user files with encryption and displays a ransom-demanding message on their screen. Dever attacks a computer secretly and targets commonly used file types such as images, video and audio files, documents and archives.

The .Dever Virus will encrypt your files.

You realized that you have been infected with Dever most likely after you saw a disturbing alert on your computer’s screen. Sadly, this program is indeed a malware type, which belongs to the Ransomware category and is designed to extract money from web users through blackmail. Nonetheless, in this article, we will try our best to help you remove the Dever virus from your machine and possibly recover your most important files without paying ransom to the crooks behind it.

The Dever virus

The Dever virus is a money-extorting infection of the ransomware type that can blackmail its victims into paying ransom so as to liberate their files. The Dever virus firstly encrypts the most important digital data found on the system, and then requires a ransom payment in exchange for a decryption key.

Dever typically infects a computer in a very stealthy way. This ransomware never works alone. It typically travels in a combo with a Trojan horse virus, which actually serves as a backdoor for the ransomware to sneak in the system without being detected. Both of these infections may find their way into your computer from shareware packages, torrents or any applications downloaded from dubious sources. Both can also be inserted into emails in the form of text documents and sneak into your device when you open an infected one.

The Dever file encryption

The Dever file encryption is a stealthy process that converts user data into unreadable bits of information. In order to reverse the Dever file encryption, the victims are asked to pay a ransom for a decryption key which is held by the hackers behind the ransomware.

Once their files have been encoded and a ransom message is displayed on their screen, the victims of Dever are typically left with the impression that the only way to save their data is to pay the money that the crooks require. The hackers typically promise to send a special decryption key to those who fulfill their ransom payment demands. Nonetheless, it’s never a good idea to believe some anonymous hackers, as they are only after your money. Once they receive the payment, there is nothing that can make them send you the promised decryption key or whatever file-recovery solution they offer. Therefore, we strongly recommend that you keep your money and focus on how to remove the Dever ransomware with the help of our removal guide below. Its file-recovery suggestions may even help you restore some of your files for free.

Perhaps the most important piece of advice in Ransomware security, however, is to remember to create copies of your most important files as often as possible. Keep backup copies somewhere outside your computer on an external drive or a cloud, as in this way you can always recover them in case of a ransomware attack or an accidental data loss.
