Radamant ransomware - How to remove

Radamant ransomware

Radamant ransomware is a malicious application that comes from the same family as .vvv extension virus, TeslaCrypt and some other latest ransomware. Just like its predecessors, the program is distributed with spam emails, as a PDF or Microsoft Word file attachment. Once installed, Radamant ransomware encrypts your files and asks for a ransom of .5 BTC (Bitcoin) which is more that $200, if you want to get your files back.

Unfortunately, even if you pay the ransom, there are no guarantees that you will regain control over your data. If you have you files backed up, it is much better to restore them from there. Then you must remove Radamant ransomware from your computer.

About Radamant ransomware

If you have opened a malicious email, Radamant ransomware kit will infect your system and save it in %Temp% folder as a .tmp file. Then it will scan your drives and look for files to encrypt. The encryption is performed using AES-256 algorithm. Extensions of all encrypted files will be changed to .RDM and you will receive a warning saying that your files are at risk. Here is what is says:

Additionally, the program deletes all volume shadow copies, so you would not be able to recover your files manually. The best way to get your files back, is restoring them from a backup.

How to avoid Radamant ransomware

We highly recommend installing a reliable anti-malware program, like Spyhunter or StopZilla and keep them updated. Make sure you also don’t visit suspicious websites and obviously stay away from opening spam emails or emails from unknown senders. Radamant ransomware often try to mislead users by sending emails that supposedly contain some important documents, so be careful what you open, even if it looks like legitimate.

Step 3. Restore Radamant ransomware affected files using Shadow Volume Copies

If you do not use System Restore option on your operating system, there is a chance to use shadow copy snapshots. They store copies of your files that point of time when the system restore snapshot was created. Usually Radamant ransomware tries to delete all possible Shadow Volume Copies, so this methods may not work on all computers. However, it may fail to do so. Shadow Volume Copies are only available with Windows XP Service Pack 2, Windows Vista, Windows 7, and Windows 8. There are two ways to retrieve your files via Shadow Volume Copy. You can do it using native Windows Previous Versions or via Shadow Explorer. a) Native Windows Previous Versions Right-click on an encrypted file and select PropertiesPrevious versions tab. Now you will see all available copies of that particular file and the time when it was stored in a Shadow Volume Copy. Choose the version of the file you want to retrieve and click Copy if you want to save it to some directory of your own, or Restore if you want to replace existing, encrypted file. If you want to see the content of file first, just click Open.

Step 4. Use Data Recovery programs to recover Radamant ransomware encrypted files

There are several data recovery programs that might recover encrypted files as well. This does not work in all cases but you can try this:
  • We suggest using another PC and connect the infected hard drive as slave. It is still possible to do this on infected PC though.
  • Download a data recovery program.
  • Install and scan for recently deleted files. Data Recovery Pro
Note: In many cases it is impossible to restore data files affected by modern ransomware. Thus I recommend using decent cloud backup software as precaution. We recommend checking out Carbonite, BackBlaze, CrashPlan or Mozy Home.
