Serpent virus Removal Guide
Description of Serpent ransomware
What can you expect from Serpent ransomware virus?
Serpent ransomware virus mostly attacks Danish computer users and encrypts files using strong encryption algorithm.
Danish computer users should be extremely careful because Serpent ransomware mostly attacks people living in Denmark. However, no one should feel safe because it might reach you no matter where you live. The virus spreads via malicious spam emails, and once a victim lets it inside, it check’s computer’s IP address.
If the virus finds out that it managed to get inside the computer located in Azerbaijan, Belarus, Georgia, Kazakhstan, Kyrgyzstan, Moldova, Russia, Tajikistan or Turkmenistan, it exists and does not touch the files. Otherwise, Serpent virus enters the system and starts data encryption procedure.
The virus targets 876 different file types and encrypts them with RSA-2048 and AES-256 ciphers. Once the encryption is over, all encrypted files have .serpent file extension, and users find two new files on the desktop. These two files are ransom notes called HOW_TO_DECRYPT_YOUR_FILES_[random_3_chars].html and HOW_TO_DECRYPT_YOUR_FILES_[random_3_chars].txt.
Of course, cybercriminals ask to pay 0.75 Bitcoins to restore encrypted files and give 7 days time to make a transaction. What happens later? The size of the ransom increases to 2.25 Bitcoins.
Is it worth paying the ransom? Absolutely not. You may not receive a necessary software from the cyber criminals. Thus, it’s better to remove Serpent instead of taking this risk. Install and scan your computer with ReimageIntego in order to get rid of this cyber parasite. However, if you have some difficulties, please scroll down to the end of the article to get help.
Serpent ransomware is a new variant of Hades Locker and WildFire viruses. However, you can be sure that developers improved their previous creations and developed a more hazardous cyber threat. On the affected computer the virus connects to the Command and Control server in order to send victim’s IP address and country, hardware ID and campaign ID.
Then, the server responds with a unique encryption key that cannot be simply unlocked. Unfortunately, Serpent removal won’t restore encrypted files. As we already mentioned, paying the ransom is not a recommended option as well. We have to be honest and tell that chances to recover encrypted files are not high. The virus also deletes Shadow Volume Copies that are useful in data recovery. However, sometimes ransomware fails to perform all its tasks correctly. In this case, there’s a way to restore at least some of the files encrypted by Serpent virus.
How does this ransomware get inside the computer?
Developers of the Serpent malware use the traditional ransomware distribution technique – malicious email attachments. As we revealed at the beginning, the virus aims at Danish computer users and wants to trick them into opening an invoice. Malicious emails have “Sidste påmindelse for udestående faktura 1603750” subject line. Thus, if you receive this email, delete it immediately! The email has a word file that asks to enable Macro commands.
Once the victim clicks on “Enable content” button, the virus is dropped under %AppData% directory and executed. Therefore, you have to be extremely careful with emails and do not rush opening attached documents. Make sure you can rely on the sender, and the explained issue seems legitimate.
How to remove Serpent ransomware from the PC safely?
The only safe way to remove file-encrypting virus from the computer is using malware removal tools. Do not even think about manual Serpent removal! It’s a dangerous and complicated cyber threat that might be hiding deeply in the system. What is more, you might accidentally delete important system file instead of malicious one. Do not cause yourself more problems than you already have. Install ReimageIntego or SpyHunter 5Combo Cleaner and run a full system scan.
If malware is resistant, reboot your PC to the Safe Mode with Networking and try again to remove Serpent automatically.

It is strongly recommended to take precautions and secure your computer from malware attacks. To protect your PC from Serpent and other dangerous viruses, you should install and keep a powerful malware removal tool, for instance, ReimageIntego, SpyHunter 5Combo Cleaner or Malwarebytes.
How to prevent from getting ransomware
A proper web browser and VPN tool can guarantee better safety
As online spying becomes an increasing problem, people are becoming more interested in how to protect their privacy. One way to increase your online security is to choose the most secure and private web browser. But if you want complete anonymity and security when surfing the web, you need Private Internet Access VPN service. This tool successfully reroutes traffic across different servers, so your IP address and location remain protected. It is also important that this tool is based on a strict no-log policy, so no data is collected and cannot be leaked or made available to first or third parties. If you want to feel safe on the internet, a combination of a secure web browser and a Private Internet Access VPN will help you.
Recover files damaged by a dangerous malware attack
Despite the fact that there are various circumstances that can cause data to be lost on a system, including accidental deletion, the most common reason people lose photos, documents, videos, and other important data is the infection of malware.
Some malicious programs can delete files and prevent the software from running smoothly. However, there is a greater threat from the dangerous viruses that can encrypt documents, system files, and images. Ransomware-type viruses focus on encrypting data and restricting users’ access to files, so you can permanently lose personal data when you download such a virus to your computer.
The ability to unlock encrypted files is very limited, but some programs have a data recovery feature. In some cases, the Data Recovery Pro program can help recover at least some of the data that has been locked by a virus or other cyber infection.
