YafunnLocker virus Removal Guide

What is YafunnLocker ransomware virus?

YafunnLocker ransomware attacks the virtual community

YafunnLocker virus has set out into the cyber wild. Since it is another file-encrypting malware, it is able to encrypt the files with an elaborate cipher. Its name stems from an email address which is displayed in the ransom note of this virtual threat. You might get informed that you must contact cyber criminals via Yafunn@yahoo.com to remit the payment of one or two Bitcoins. The most important thing related to this virus is that it encrypts your files with the RSA-2048 algorithm. The key which is generated by this code cannot be easily guessed, so the only possible way to recover your data seems to be the financial transaction. However, this might be futile. We highly recommend staying away from this data recovery method. Therefore, you should deal with YafunnLocker removal procedure first. If you are looking for a reputable virus removal solution, we suggest FortectIntego.

Talking about the virus itself, there are interesting things that can be pointed out. For instance, some researchers associate YafunnLocker ransomware with the CryptoLuck family what uggests that this parasite may be deployed on computers via RDP, TeamViewer or other vulnerabilities it finds within the system’s perimeter. Howwever, some users report that the virus hijacks DLL via a fake GoogleUpdate or is simply delivered by email. What is certain, though, is that at least to some extent, the virus developers take advantage of the Rig exploit kit which has just recently been found to spread another major ransomware infection – the Locky virus. Either way, finding such a virus on your computer can be very stressful — you have lost access to your files and some strange pop-ups are demanding you to pay to make things right again. Do not lose your cool if such situation ever occurs. Cut the network connection immediately and remove YafunnLocker malware from your PC. Though this technique will not help you decrypt the files, it is a much better option than keeping the virus on your computer and allowing it to lock your future documents or programs.

Though some experts note similarities with other ransomware infections, this malware has enough individual qualities that distinguish it from the rest. For instance, it pins the extension which is called as .[A-F0-9]{8}_luck to the infected files. This extension is one of the reasons why YafunnLocker virus has been associated with CryptoLuck in the first place. The ransom note that this virus leaves on the computer allows us to learn even more about this program as well. For instance, the hackers indicate two email addresses: bortanofe@hotmail.com and framozes@yandex.ru that the user has to contact to receive further data recovery instructions. Yandex.ru is a well-known website associated with numerous browser hijackers and similar viruses that stem from Russia. Perhaps it is a far-fetched speculation, but it might be that either the hackers themselves come from this country or specifically target Russian-speaking countries with this virus. So, far, there is not evidence on neither of these theories. While the experts are trying to learn more about this infection, we suggest not to hang around and take action regarding YafunnLocker removal. If you do not know where to start, just keep reading this article, and you’ll get there.

The distribution and prevention measures

YafunnLocker, like most ransomware viruses, is not easily tamed. You cannot avoid it by simply installing an antivirus utility and hoping for the best. You must take care of the layered protection. This layered protection may include, but is not limited to:

  1. Installation of a reputable computer protection utilities. Though it will not protect your computer on its own, it is crucial to have a reputable antivirus utility installed for the prevention of initial threats and the further virus removal. It might also be backed-up with some powerful firewall.
  2. Careful behavior online. If you do not visit unfamiliar websites, click on random ads, download unknown software or open email attachments that come from unknown senders, you significantly diminish the risk of getting infected with ransomware.
  3. The methods mentioned before are tricky because Yafunn Locker can find ways to bypass them. This means that, essentially, there is no way of knowing when will the virus strike. Thus, a more reasonable data protection can be achieved only by making regular backups of your data and storing them on external devices.

How quickly can I eliminate YafunnLocker?

Unfortunately, the ransomware still has not been decrypted. This means that there is currently no way of fully decrypting the locked data and doing it safely.

How to prevent from getting ransomware

Stream videos without limitations, no matter where you are

There are multiple parties that could find out almost anything about you by checking your online activity. While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.

Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful Private Internet Access VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.

Data backups are important – recover your lost files

Ransomware is one of the biggest threats to personal data. Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.

While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as Data Recovery Pro can also be effective and restore at least some of your lost data.
