Vanss virus Removal Guide
What is Vanss ransomware?
Vanss ransomware is a cryptovirus that uses the same email address as previous Dharma versions
Vanss ransomware is a cryptovirus that encodes your files using AES algorithm.
Vanss ransomware — a file-locking malware that adds .vanss file extension after it finishes its encryption process. This is the newest variant of Dharma ransomware that looks identical to previous versions and uses the same firstname.lastname@example.org contact email as previous threats released since May 2018. Typically to other versions hailing from this ransomware family, Vanss appends ransom note in the form of FILES ENCRYPTED.txt and Info.hta files. These contain recovery instructions, payment methods and more information about the attack performed behind the user's back. However, the test decryption that is offered by ransomware developers is not a good idea and paying the ransom, in general, can hardly give positive results. You should focus on virus removal first before worrying about encoded data. Unfortunately, there is no official decryption tool for this particular variant yet.
|Ransom note||FILES ENCRYPTED.txt; Info.hta|
|Distribution||Spam email attachments|
|Decryption||There is no decryption tool for the particular version|
|Elimination||Use RestoroIntego for Vanss ransomware removal|
Ransomware-type threats, including Vanss ransomware, have been starting their attack from changing the registry entries, adding files to a directory or modifying additional system content. The encryption process is the final stage of the ransomware attack when all changes are already made. The virus modifies the following registry keys on the system of victims' device:
- \Registry\Machine\Software\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\996E.exe
- \Registry\Machine\Software\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\ole32.dll
- \Registry\Machine\Software\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\oleaut32.dll
- \Registry\Machine\Software\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\version.dll
- \Registry\Machine\Software\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\comctl32.dll
Additionally, ransomware works in the background until it encodes all victim's files. Cybercriminals develop this virus to scan the system and find the most used files for encryption. Previous variants use AES encryption method to make user's files useless. Every encrypted file is marked using .vanss file extension that displays which data is locked and unavailable for the use.
Once the files are encrypted, malware drops the FILES ENCRYPTED.txt and Info.hta ransom notes in every folder on the system. Unfortunately, there is no solution for encrypted data besides file backups and several options that we presented below. If you are looking for the decryption tool designed for this particular variant, we must warn you not to buy it from cybercriminals because you can be scammed.
You need to remove Vanss ransomware as soon as possible because cyber threats like these crypto-extortionists can affect the system in a more significant way. Ransomware can interact with Windows files in System folders or alter functions of an operating system without you even noticing to make the virus more persistent and dangerous.
Vanss ransomware removal can be performed using anti-malware tools like RestoroIntego or a few other that we list below the article. Scan your system thoroughly and delete all detected intruders to make your system clear again. After this, you can try data recovery methods from down below or replace your files from a safe backup.
Vanss ransomware virus is yet another Dharma version that uses the same files as a ransom note and the same email address since May.
File attachments on spam emails used to infect computers
The most effective tactic used to spread ransomware intruders effectively is spam email attachments. Files added as an attachment to email message usually pose to be secure documents from services or companies. It may look like you got an invoice, a receipt, order information or banking statement. Senders often imitate big companies like PayPal, eBay or Amazon, and DHL.
However, these files are often be filled with macros or designed to self-extract the malicious file or even direct malware payload. Researcher note that URLs on these email may also be infected and spread cyber infections immediately after you enter the website. Opening the page automaticaly downloads the ransomware and installs the malicious file. Clean the email box more frequently and avoid any suspicious email. Do not open the email you haven't expected.
Remove Vanss ransomware and all related files using reputable anti-malware
When it comes to cyber threats as dangerous as cryptocurrency demanding ransomware, virus elimination is a necessary and challenging process. To remove Vanss ransomware from the system completely, you need to employ anti-malware tools like RestoroIntego, SpyHunter 5Combo Cleaner or Malwarebytes. These programs detect malware, corrupted files, and other virus damage and delete possible threats entirely off the device.
Automatic Vanss ransomware removal is the best solution because there are tons of changes you cannot find manually. And data recovery cannot be made on an infected device because ransomware performs yet another encryption on newly added files. Double-check if the system is clear before adding new files on the computer or attempting data recovery. You may need to enter the Safe Mode before scanning the system, so your antivirus works properly.
Getting rid of Vanss virus. Follow these steps
Manual removal using Safe Mode
Try rebooting your device in Safe Mode with networking before a full system scan to properly remove Vanss ransomware:
Manual removal guide might be too complicated for regular computer users.

Decryption tool is not developed yet
Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from Vanss and other ransomwares, use a reputable anti-spyware, such as RestoroIntego, SpyHunter 5Combo Cleaner or Malwarebytes
How to prevent from getting 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.
