Frozrlock Ransomware Removal Guide

Do you know what Frozrlock Ransomware is?

Frozrlock Ransomware is a serious threat that you might also recognize as FileFrozr Ransomware. According to the information gathered during the research that was conducted in our internal lab, this ransomware was created using an open-source code that can be employed by anyone. The structure of the ransomware can be purchased in the DarkWeb for a mere 150 USD. The builder is made available at frozrlockqqxz7a2.onion.link. What this means is that there can be a ton of different versions of this threat. Although the main details stay the same, the ransom messages could be represented in different languages, depending on the regions that cyber criminals choose to target. Also, these different versions of the ransomware could be recognized by different names. In this report, we show how to identify and remove Frozrlock Ransomware from your operating system. Unfortunately, if it has slithered in, your files must be encrypted, and the chances of getting them decrypted are very slim.

According to our research team, Frozrlock Ransomware is most likely to be spread via spam emails, in which the malicious installer is concealed as a harmless attachment. Once you open this attachment, the ransomware firstly creates a copy in %APPDATA% (in our case, it was named “UpdateServices.exe”). By doing this, the ransomware ensures that the encryption is performed even if you delete the launcher file quickly. The copy file communicates with a remote C&C server (at 104.20.16.242) to transfer data about you and your operating system, as well as to initiate the encryption process. It was found that Frozrlock Ransomware can use AES-256 and RSA-4096 keys to encrypt your files. This infection can encrypt all kinds of files, including .exe files that represent applications. Of course, it does not encrypt the files that are found in the %WINDIR% directory, as well as Windows components, so as not to disrupt your operating system; otherwise, the attack would fail.Frozrlock Ransomware Removal GuideFrozrlock Ransomware screenshot

Frozrlock Ransomware does not attach a unique extension to the files it encrypts. That is not common, and most threats of this kind – including BitKangoroo Ransomware, Extractor Ransomware, or AES-NI Ransomware – attach extensions to help users find the encrypted files quicker. Unfortunately, this can create problems for you when identifying the corrupted files. To inform you about the encryption, the infection creates a file called “THIS_YOU_MUST_READ.txt”. You should find it on the Desktop. If you follow the instructions represented via this file, you will pay a ransom of 0.1 Bitcoin (~170 USD). Although the link via which the payment must be paid includes a unique ID number, and you can decrypt one file for free, we cannot guarantee that you would be able to decrypt your files by paying the ransom. In most cases, ransomware creators scam their victims into paying money without providing them with what is promised. You have to keep in mind that this could be the case with Frozrlock Ransomware as well. All in all, deleting this ransomware is crucial.

Whether or not you get your files decrypted, you must delete Frozrlock Ransomware as soon as you can. This ransomware is controlled by extremely vicious cyber criminals, and you are at risk for as long as this threat is active. The instructions below show how to remove Frozrlock Ransomware manually, but this is not the best option you have. According to our malware experts, it is wise to install anti-malware software because, first of all, it can ensure full removal of all existing threats, and, second, it can ensure reliable protection against malicious infections in the future, and that is very important. More and more ransomware infections are found each day, and they are becoming stronger and more aggressive. Due to this, you have to do whatever it takes to keep yourself guarded.

Delete Frozrlock Ransomware

  1. Right-click the {unknown name}.exe file that is the launcher.
  2. Delete this file.
  3. Tap Win+E keys to launch Explorer.
  4. Enter %APPDATA% into the bar at the top.
  5. Right-click and Delete the copy of the launcher (could be named UpdateServices.exe).
  6. Empty Recycle Bin.
  7. Perform a full system scan to check if your operating system is malware-free.

In non-techie terms:

Recovering the files encrypted by Frozrlock Ransomware might be impossible, but removing this threat is not. If all of your files are backed up, you should not hesitate to delete this infection for much longer. If your files are not encrypted, you might want to postpone this operation, but you should not wait long because this ransomware is incredibly malicious and dangerous. Because it can encrypt .exe files, it is most likely that you cannot launch your web browser either. If you choose to remove the ransomware manually, you can use the guide above. If you decide to install an anti-malware tool, you might have to transfer the installer using a flash drive. You can do the same with a browser installer, and other apps that might have been corrupted by the ransomware. We advise using anti-malware software because of the protection it can provide you with after removing all threats.
