How to remove BestChangeRu ransomware

BestChangeRu ransomware is the cryptovirus that targets Russian users and demands 25 000 Rubles in Bitcoin 

BestChangeRu ransomware is the crypto-extortion based virus that encrypts users' data and requires ransom to return files. Once your files are locked with a robust encryption algorithm, ransomware places инструкция по оплате.txt (payment instruction.txt) ransom note on the system and informs victims about how to proceed next. BestChangeRu virus authors demand 25 000 Rubles in Bitcoin, although they also note in the message that the price doubles after 48 hours. There is no guarantee that the alleged decryption tool exists, so stay away from contacting these people and remove BestChange Russia ransomware instead. Since the ransom note is written in the Russian language, it is clear that virus authors are targeting Russians, although it does not mean that victims from other parts of the world cannot be infected.

Once the system gets infected, BestChangeRu ransomware virus changes certain system settings to enable the encryption on particular types of data. It affects your photos, documents, video or audio files or even archives and databases and files after data-locking could no longer be opened. 

When BestChangeRu ransomware is done with the encryption and additional changes on the device, it delivers a ransom message in the form of the text file called инструкция по оплате.txt (payment instruction.txt) and places this file on every folder that contains locked files. The ransom note reads the following (translated from Russian):

Virus developers wrote a long message for BestChangeRu ransomware victims, and there are a few interesting features. The main focus of this note is to inform users about the payment and other actions, as the first line provides a link to BestChange website.

Further instructions on the cryptocurrency transaction show that BestChange Russia ransomware developers prefer Bitcoin over other currencies. Victims get 48 hours to pay up, but the ransom may increase by 50% after that. Based on previous ransomware victims, we do not recommend fulfilling this demand.^[2]

Another interesting fact about the BestChangeRu ransomware ransom note is the link at the very end of the text that delivers to an article about Backup rule “3-2-1”.^[3] This seems to be a joke because when your files get encrypted, data backups is the best solution for your lost files. However, you can employ special data recovery tools if you have no backups. Stay away from paying the demanded amount because it may lead to permanent money loss.

We highly recommend you to remove BestChangeRu ransomware as soon as possible so that you can avoid additional changes to the system or even virus damage. This is especially crucial when you think about data recovery later on. 

For BestChangeRu ransomware removal, you should get a reputable anti-malware program and scan the system thoroughly. During the system check, a tool can indicate all threats and remove them from the computer while cleaning the damage. We can recommend using FortectIntego for the process. 

Spam email contains infected files as attachments 

Commonly used techniques like malspam campaigns get used by ransomware developers to deliver infected files with malicious macros or malware scripts. Researchers^[4] often advise paying more attention to emails you get because of the risk this technique creates.

When you receive the email you were not expecting, pay more attention to details and information on the email itself because an URL presented in the email or the text directly like a button may load the page which triggers the extraction of malicious ransomware payload.

Also, attachments that contain malware droppers look legitimate enough for a user to download and open on the device. Stay away from files in .rar, .zip or .docx formats if attached to the email sent from questionable address. Once the document is opened or archive extracted, malicious script is triggered and releases infection on the system.

Avoid opening emails with suspicious senders or subject lines, sent from legitimately-looking service you do not use. You should delete those emails from the spam section or even the regular inbox if you are not sure about the purpose of the message. 

Eliminate BestChangeRu ransomware and make sure to clean the system fully

For the best BestChangeRu ransomware removal results, users should get automatic malware-fighting tools like FortectIntego, SpyHunterCombo Cleaner, or MalwarebytesMalwarebytes. These programs can ensure total virus termination and performance improvement of the machine.

When BestChange Russia ransomware virus infiltrates the system, in addition to the encryption process, it changes system settings and adds malicious files/processes. Because of this reason, ransomware elimination requires professional help and additional features like the Safe Mode. 

Once you remove BestChangeRu ransomware from the system entirely, you can attempt file recovery procedure. In case you do the opposite, all your recovered data will be immediately encrypted again. In case you have no backups, use our instructions for using third-party recovery applications.
