removal by Ugnius Kiguolis - -   Also known as .RDM File Extension virus | Type: Ransomware

The description of Radamant virus:

Radamant (or.RDM File Extension virus) is the latest ransomware from the same family as TeslaCrypt, .VVV file extension virus and other cyber threats. It showed up in the middle of December, 2015. Just like its previous versions, this virus spreads around with the help of spam. According to PC security experts, you can get infected with this ransomware after opening an email message having Microsoft Word or PDF file attached to it. The most of such email messages claim that they need to be opened because they are filled with financial, personal or similar information. Unfortunately, but there is only one thing that you can get after downloading such attachment to your computer. It is a trojan horse, which infects the system with Radamant ransomware kit and saves it in %Temp% folder as a .tmp file. As soon as this threat infects the computer, it checks the drive for specific characters and encrypts needed files. It does that with the help of an advanced encryption algorithm called AES-256 encryption. Also, it changes all extensions of encrypted files to .RDM extensions and starts showing a huge warning message that declares that the only way to get these files back is to pay a ransom.

Questions about Radamant ransomware

If that is the case you are dealing with, we have to disappoint you that you are in a big trouble. First of all, files that were encrypted by Radamant cannot be decrypted without a special decryption key. To get it, you have to pay a ransom of almost $300. This payment should be made in a form of bitcoins within several days. Otherwise, virus damages this key and buries affected files. Besides, you can be scammed and lose your files AND money What can you do in such situation? First of all, you have to disconnect your computer from the Internet to prevent the additional loss of your important data. Also, run a full system scan with Reimage and remove malicious files related to Radamant ransomware. If your photos, business documents or art files have already been encrypted, you should try to restore them from their backups. You can do this procedure with the help of two tools, known as Photorec and R-Studio. However, if they failed to work for you, you should forget these files because they are doomed.

The main warning messages of Radamant virus

That’s why security experts do NOT recommend paying a ransom for the developers of Radamant malware. More information about the removal of this virus you can find on the next page.
