How to remove Dever virus and restore encrypted files

This item is dedicated to Dever ransomware that infects laptops around the world, and corrupts their data. Here we've gathered important information about Dever's essence, and how to eliminate Dever from the system. Furthermore, we will explain how to get back the corrupted information, if possible.

Dever ransomware virus

Dever is the unwanted program getting into machines mainly via e-mail spam and Trojans. Sometimes scammers use exploits to get into the system, but well-known program companies promptly fix them. After the infection, the virus inspects the hard disc, determines the amount of files for encryption and their approximate price. At the moment, each modern virus knows how to encrypt image, audio, video and text info in all most used extensions. Dever encrypts all files, but the ones that look like business correspondence go first. Virus encrypts only information, and doesn't touch the programs, so that the user can use the PC to make the payment. Encryption is executed via world-known encryption algorithms, and it is so sophisticated that that decryption of files without a key is impossible. Such complexity is the ground for such a stunning efficiency of ransomware in last years: an ordinary customer, even having a pretty good knowledge of the computer, won't ever decrypt the files, and will have no choice except paying the ransom. The only method to recover files is to find the fraudster's website and withdraw the master key. Sometimes it is possible to obtain encryption keys due to flaws in viruse's program code.

The knowledge of computers is very significant in our world, since it assists you to defend the workstation from computer viruses. For ransomware this is very important, since, in contradistinction to regular malicious software, when you delete ransomware from the system, the consequences of its doings will stay. To protect your system, you must remember a few elementary rules:

    • Monitor the state of your computer. Data encryption is a sophisticated act that requires a large amount of computer resources. When the virus starts to work, the workstation slows down, and the encryption process can be found in Process Manager. You can catch this event and switch off the workstation before data will be totally spoiled. Surely, the certain amount of information will be damaged, but you will secure the other part.
    • Be careful with the messages which contain something more than a message. The most efficient template of fraud e-mails is the story about prize winning or parcel earning. The #2 efficient sort of scam letters is a "business letters". lawsuits, complaints, summaries, Invoices for products or services and similar sensitive files don't be sent without warning, and you, as a minimum, should know the person who sent it. Otherwise, it is a fraud.
    • Pay attention to the dialog boxes. The easiest way of data restoration is the recovery through Shadow Copies, and Web-criminals have included the elimination of SC into the primary functionality of malware. Anyway, deleting of shadow copies requires admin rights and confirmation from the operator. If you'll think for a moment before verifying the checkbox, it can save your information and your time.
