UltraCrypter Ransomware Removal Guide

UltraCrypter Ransomware might be a slightly modified version of a Trojan infection known as CryptXXX Ransomware. Consequently, they work in a very similar manner, but while researching the malware, we noticed some changes too. Further in the article we will explain more about the ransomware. Also, we will add a step by step removal guide that should help you erase the infection if you decide to get rid of it. So far, it does not seem like anyone managed to develop a decryptor yet. Thus, it might be impossible to recover your data if you did not make any copies of it on a removable media device, remote cloud or elsewhere. You may think that paying the ransom guarantees that you will be able to recover your files. Unfortunately, no one can offer you any reassurances, so you might want to think it through once more.

UltraCrypter Ransomware installs itself without your permission. The question is how it manages to do that. Specialists say that your computer might have been infected with Angler Exploit tool. It can detect any security flaws on your system and use them to install the malware. During the process, a malicious .dll file could be placed in the Temporary files directory. Besides, it adds a copy of a rundll32.exe file that could be taken from the %WINDIR%\SysWOW64 or %WINDIR%\System32 directory. This file belongs to your system, so it is not malicious. The infection uses rundll32.exe to launch the .dll file and with that the installation should be completed.

The interesting part is that UltraCrypter Ransomware takes some time before it starts encrypting your data. To be more precise users have from 15 to 62 minutes in which they can try to erase the malware. Otherwise, it encrypts all personal data on your computer. The malware’s goal is to take your precious data as a hostage and demand you to pay a ransom. Naturally, the ransomware’s creators try to convince you that they will unlock your data once the payment is made. Their demands and promises are stated in the ransomware’s web page that you can reach if you open the .html file, which could be added to your Desktop. The site contains instructions that should tell you how to transfer the ransom too. Also, UltraCrypter Ransomware might leave .txt or .bmp files that provide similar information or its shorter version.

Sadly, some users give away their savings as they think that they have no other option. In fact, there is always another solution. For example, you can remove the infection and replace the encrypted data with copies from removable media devices. Even if you do not have any copies, paying the ransom is a risky thing to do. People who make their living by creating such malware are not very honest, so they might not keep their promise. Users who want to erase UltraCrypter Ransomware can do that with the instructions located below the text, although manual removal might be a bad idea if you are an inexperienced user. Thus, it is more advisable to download a security tool and allow it to take care of the malware. This way, you would also acquire a tool that could protect you from various threats in the future.
