SNTG virus Removal Guide
What is SNTG ransomware?
SNTG ransomware – new file-locker from the Matrix family
SNTG ransomware is a data-locking computer infection that uses extortion techniques to make victims pay ransoms
SNTG ransomware is a cryptovirus that renders infected computer files inaccessible by encrypting them with a strong algorithm, and a ransom is required to unlock them. Originating from the Matrix ransomware family, the virus encrypts documents, photos, audio/video files, archives, etc. All of those non-system files receive a complex three-part extension. It consists of the email address of the criminals who distributed this virus, a sequence of random characters, and .SNTG appendix.
After the encryption process is finished, ransom notes named #SNTG_README#.rtf are created and scattered on all locations throughout the computer. Within that note, developers of SNTG ransomware are trying to allure their victims into meeting their demands by saying that only they have the required decoding tool and decryption key needed to unlock the data. In most cases, that's true, but dealing with cybercriminals is a risky business, and we advise against it. They provide a unique personal ID, which should be sent to them when establishing contact via their three given emails (victims should write to all of them at once):
As proof that they possess the needed tools for decryption, the cybercriminals offer to send them three small files from the infected machines to be unlocked for free (files shouldn't include any sensitive data). They also threaten that if the victims try and recover files by themselves or third-party tools, the data might be damaged and lost forever. There are no more details about the ransom amount, or the preferred payment method is mentioned.
|name||SNTG ransomware, .SNTG virus|
|family||Matrix ransomware family|
|appended file extension||All non-system files are renamed using a three-part extension: criminal contact email in brackets, a sequence of random characters in brackets, and .SNTG appendix|
|Criminal contact info||Three emails are provided to contact the criminals: SantaGman@criptext.com, SantaGman@protonmail.com, SantaGman@tutanota.com|
|infection aftermath||All personal data cannot be opened and is renamed|
|malware removal||SNTG ransomware removal should be entrusted to a professional anti-malware software|
|system fix||To run a full system scan, find out and fix whatever the virus has done, we advise using the ReimageIntego tool|
Although meeting criminal extortion demands to retrieve your data might seem like the only available option, please refrain from doing that. When cybercriminals like the creators of the .SNTG virus achieve their goals, i.e., get paid, that fuels their business and motivates to expand. And there's absolutely no guarantee that you will receive the promised tools to decrypt your files. There are numerous cases where the victims got scammed even more.
In case you're one of the unlucky ones that got the device infected, you should delete the infection immediately. To remove SNTG ransomware, we recommend using either SpyHunter 5Combo Cleaner or Malwarebytes anti-malware software. These apps will do the work for you because removing it manually might be extremely hard even for tech-savvy computer users.
Cryptoviruses are known to altercate various system settings and files to help with its purpose of encryption and extortion. Experts suggest using the ReimageIntego tool after a successful SNTG virus removal to check and repair what damage the malware had done.

SNTG ransomware is a variant of the broad Matrix virus family
Malware distribution techniques
Cybercriminals are good at what they do, so everyday computer users should be attentive while browsing the internet. The most common way for the perpetrators to infect computers is by using file-sharing platforms and email spam.
In file-sharing platforms, like torrent sites, cyberthieves usually hide their creations as various illegal activation tools (cracks) for games or software. Users should never use those sites to get their desired programs or they might become the next victims. Instead, support your beloved game or desired app developers by buying directly from their official websites.
Cybercriminals conduct spam email campaigns, i.e., they send out an enormous amount of emails to everyday computer users all over the world. Those spam emails might contain either hyperlinks to malicious sites or infected attachments. Never open emails if you don't know the sender and always scan attachments with a reliable anti-malware app before downloading them.
Guidelines to remove SNTG ransomware
Ransomware is a dangerous type of malware that not only encrypts victims' files and demands a ransom for a decryption tool, but it also modifies system settings and its files to help it achieve its goal. We highly advise never to pay the ransom and eradicate the virus immediately.
SNTG virus can be detected by many security applications
To remove SNTG ransomware, we suggest using a time-proven SpyHunter 5Combo Cleaner or Malwarebytes software. Do a full system scan and delete all the files that the might have been important by malware.

How to prevent from getting SNTG ransomware
Protect your privacy – employ a VPN
There are several ways how to make your online time more private – you can access an incognito tab. However, there is no secret that even in this mode, you are tracked for advertising purposes. There is a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of Private Internet Access VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise. Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and Private Internet Access VPN will let you browse the Internet without a feeling of being spied or targeted by criminals.
No backups? No problem. Use a data recovery tool
If you wonder how data loss can occur, you should not look any further for answers – human errors, malware attacks, hardware failures, power cuts, natural disasters, or even simple negligence. In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.
If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. Data Recovery Pro is one of the leading file recovery solutions you can find on the market – it is likely to restore even lost emails or data located on an external device.
