A ransomware is a virus that infects the computer and causes serious issues to PC user’s important files. It aims to locate valuable data, encrypts them using a complex algorithm, and locks it to become inaccessible. To regain access to the files, the attacker will demand a ransom fee in exchange for a decryption tool and private key. One example of this hazardous threat is called Remk Ransomware.
About Remk Ransomware
Remk is a kind of crypto-virus, which encrypts majority of victim’s files in order for handlers to ask for a ransom fee. When certain files suddenly become inaccessible, we may conclude that something is not right and probably a ransomware is the reason behind it. Remk will rename the targeted files by appending .remk extension. The victims will then receive instructions within a note named “_readme.txt” stating how to recover the encrypted files. The ransom fee covers the purchase of a decryption tool and private key. The costs usually demanded by data hackers ranges from $490 to $980 depending on how soon victims can contact them. Cyber criminals typically use crypto-currency, so the payment will be in Bitcoin digital currency.
How Remk ransomware works
Data-locker software or ransomware can access computers in so many ways. But the most efficient way to deliver their virus code is through spam email attachments. Remk operators will send emails to their targets pretending to be from prominent organization in order to gain trust. However, the email contains a ransomware-infected file attachment. Once opened, it results to invade the computer system, most especially when a ransomware have built-in tool for tricking PC user into allowing administrative access. After that, it will start to spy throughout the computer and encrypts the most significant files such as photos, personal documents, and so on.
Unfortunately, only Cloy developers have the decryption key for recovering the encrypted files. Therefore, victims tend to settle the payments because they have no other option. Nevertheless, computer security experts suggest that it is not a good solution. Instead, focus on removing Cloy ransomware from the computer.
How to Remove Remk Ransomware
Ransomware files are placed deeply into the system and on various locations, thus, thorough scanning is vital to totally remove Remk virus. Aside from our suggested tool, you may also run your own security program.
Though affected files may be impossible to decrypt due to complexity of the encryption, you can still try recovery method like alternative tool, Shadow Explorer or Previous Version as described below.
Stage 1: Scan the Computer with Anti-Malware Tool
1. Download free anti-malware scanner called MalwareBytes Anti-Malware.
Malwarebytes Anti-Malware Download Link (this will open a new window)
2. After downloading, install the program. It may run automatically or you have to double-click on the downloaded file MBSetup.exe.

4. After the installation process, click the Get Started button to launch the program.
5. Continue with the prompts until the main program opens.
6. On the main console, click on Scan to run most complete detection method to find hidden objects associated to Remk ransomware.
7. Scanning may take a while. Please wait until the anti-malware tool is done with the checking.
8. Once the scan has completed, the tool will display the list of detected threats. Remove all identified malicious items and restart the computer if necessary.
Stage 2: Double-check for Remk’s leftover with Microsoft’s Malicious Software Removal Tool
1. Download the free scanner called Malicious Software Removal Tool.

It was not designed to protect the computer.
5. Next, you will see Scan Type. Please choose Full Scan to ensure that all Remk ransom virus entities and other harmful files left on the computer will be found and removed. For advanced computer user, you can opt for Customized Scan, if there are other drives or folders you wanted to include in this scan.
6. Full scan may take a while, please wait for Malicious Software Removal Tool to complete the tasks. However, you may cancel the scan anytime by clicking on the Cancel button.
7. After scanning, the tool will reveal all identified threats. There may be other threats that our first scan fails to detect. Please remove/delete all detected items.
8. When removal procedure is complete, you may now close Malicious Software Removal Tool. We hope that Remk ransomware have been completely deleted from the computer. Please restart Windows to proceed with the normal operation.
Stage 3 : Unlocking files with Remk Decryption Tool
Emsisoft Decryptor for STOP Djvu will work only if affected files were encrypted using Offline Keys. Remk ransomware uses the alternate Offline Keys during encryption if there is a problem encountered while communicating to a remote command-and-control server. Follow the guide to start recovering .remk encrypted files.
1. As precautionary measures, we suggest to BACKUP all your .remk encrypted files first on a separate media (USB Drive, Flash Drive, DVD Discs, etc…).
2. Download Emsisoft Decryptor for STOP Djvu from this archive page.
3. Right-click on decrypt_STOPDjvu.exe and click “Run as Administrator“. Windows may prompt “Do you want to allow this app…” just click Yes to continue.
4. By default, the tool will pre-populate the locations where encrypted files were identified. To include other directories, simply click Add Folder button.
5. To start recovering files infected by Remk ransomware, click on Decrypt button to start the procedure. The interface will display status of the current decryption process.
We will update this section once the full decryption tool is on hand. In the meantime, please try other options below if the above procedure is not not effective.
Option 1: Windows Previous Version Tool
Windows Vista and Windows 7 have a feature called Previous Versions. However, this tool is only usable if restore point was made prior to Remk ransomware infection. To use this tool and recover files affected by the virus, please follow these steps:
