The article presents detailed information about Yogynicof ransomware as well as a step-by-step guide on how to remove its malicious .log files from an infected system. You will also be presented with a how-to potentially recover encrypted files guide.
Yogynicof Ransomware
Yogynicof virus is a vicious crypto infection that is rated as an extremely advanced threat. When it is started on a computer operating system, Yogynicof ransomware disrupts system security and encodes personal files with the help of a strong cipher algorithm, putting the .log extension to them. Encrypted files could be recognized by a renamed extension. At the end of the attack, Yogynicof ransomware virus creates a ransom message that urges you to pay a ransom for a decryption tool. This message pop-ups on the PC screen. It links to a website where more instructions on the ransom payment process could be found.

Yogynicof Virus – How Does It Infect?
The Yogynicof ransomware is a new file encrypting virus that has been recently detected in an ongoing attack campaign targeting computer victims worldwide. It still under active analysis by security experts as the hackers are unknown, as well as the general intention of the intrusions.
Like other malware of this category ransomware are distributed using common infection mechanisms. The most effective and popular way is to confuse the users into installing the virus code. It can be placed in different type of carrier files, many of which can be spread to the users in the form documents (across all popular formats), as well as application installers of popular software.
The virus-infected data can then be distributed to the end users via phishing strategies. They are designed to impersonate messages and notifications that appear as being sent by legitimate services and companies. The usual forms are email messages and hacker-created sites. All of them mayh insert or directly attach the virus files and when the users click on them the infection will be triggered.
A related mechanism is the creation of web browser hijackers which are malicious extensions for popular web browsers. They commonly installed by browsing to third-party repositories, hacker-controlled sites and even on the official stores by using fake or stolen developer credentials. Smaller executables that can have the virus included in them can be in the form of patches, software updates or “cracks”
Yogynicof Virus – What Does It Do To Your Computer?
When the Yogynicof virus is installed on a given computer it will start the built-in infection sequence. It can be controlled according to the local machine conditions or the hacker specific rules.
As the collected samples the Yogynicof ransomware is still not analyzed entirely as only a few samples have been collected. One of the collected samples shows how a virus intrudes onto a given computer. It will create a guarded memory region into which the ransomware will inject itself into. From there on it will run all other actions as intended — for example the information scan will be done afterwards. The information retrieval can be divided into two main categories: machine information and private user information. This can be used to generate an unique ID according to the collected report. The private user information can be used for various other crimes such as identity theft.
The collected information can also be searched for remote desktop credentials which are used to login remotely to the infected computers.
The Yogynicof ransomware will also be able to determine the region and language support of the installed host. Alongside the collected information this can be used by the virus creators to show in which region the malare is most succesful.
When it has gained access to the file system the virus will be able to access all system and user files. This can also be extended to any removable devices or network shares.
This is potentially very dangerous as the hackers can easily update the core files to include a worm spreading model which can automatically infect other computers on the same network. The virus will also hook up to running processes which can be used to harvest data entered into forms and fields by the victims.
When everything has finished running the actual file encryption will be run. Like other threats of this category a built-in list of target data will be encrypted. They will be locked and renamed, so that the computer users will not be able to access them. The Yogynicof ransomware will encrypt user files and not add in a specific extension at this point.
The user swill notice a lot of HTML files created in a particular sequence such as the following: Read-me! 0 .html, Read-me! 1 .html, Read-me! 2 .html and so on. They contain the ransom note which includes the instructions to the affected users.
How to Remove Yogynicof Ransomware Virus
The so-called Yogynicof virus is a threat with a highly complex code that disrupts system security in order to encrypt personal files. Hence the infected system could be used in a secure manner again only after the complete removal of all malicious files and objects created by Yogynicof ransomware. That’s why it is recommendable that all steps presented in the Yogynicof virus removal guide below should be completed. Beware that the manual ransomware removal is suitable for more experienced computer users. If you don’t feel comfortable with the manual steps navigate to the automatic part of the guide.
How to Recover Yogynicof Ransomware Files
There are several alternative methods that may be efficient for the recovery of .log files. You could find them listed in our Yogynicof ransomware removal guide. Beware that you should make copies of all encrypted files and save them on a flash drive for example. This additional step will prevent the permanent loss of encrypted Yogynicof files.

Step 2: Uninstall Yogynicof and related malware from Windows
Here is a method in few easy steps that should be able to uninstall most programs. No matter if you are using Windows 10, 8, 7, Vista or XP, those steps will get the job done. Dragging the program or its folder to the recycle bin can be a very bad decision. If you do that, bits and pieces of the program are left behind, and that can lead to unstable work of your PC, errors with the file type associations and other unpleasant activities. The proper way to get a program off your computer is to Uninstall it. To do that:
Follow the instructions above and you will successfully delete most unwanted and malicious programs.
Step 3: Clean any registries, created by Yogynicof on your computer.
The usually targeted registries of Windows machines are the following:
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
You can access them by opening the Windows registry editor and deleting any values, created by Yogynicof there. This can happen by following the steps underneath:
Tip: To find a virus-created value, you can right-click on it and click "Modify" to see which file it is set to run. If this is the virus file location, remove the value.
Before starting "Step 4", please boot back into Normal mode, in case you are currently in Safe Mode.
This will enable you to install and use SpyHunter 5 successfully.
Step 4: Boot Your PC In Safe Mode to isolate and remove Yogynicof
Step 5: Try to Restore Files Encrypted by Yogynicof.
Method 1: Use STOP Decrypter by Emsisoft.
Not all variants of this ransomware can be decrypted for free, but we have added the decryptor used by researchers that is often updated with the variants which become eventually decrypted. You can try and decrypt your files using the instructions below, but if they do not work, then unfortunately your variant of the ransomware virus is not decryptable.
Follow the instructions below to use the Emsisoft decrypter and decrypt your files for free. You can download the Emsisoft decryption tool linked here and then follow the steps provided below:
1 Right-click on the decrypter and click on Run as Administrator as shown below:

4. Click on "Decrypt" and wait for your files to be decoded.
Note: Credit for the decryptor goes to Emsisoft researchers who have made the breakthrough with this virus.
Method 2: Use data recovery software
Ransomware infections and Yogynicof aim to encrypt your files using an encryption algorithm which may be very difficult to decrypt. This is why we have suggested a data recovery method that may help you go around direct decryption and try to restore your files. Bear in mind that this method may not be 100% effective but may also help you a little or a lot in different situations.
