Nagini virus Removal Guide

Description of Nagini ransomware virus

Nagini virus is as sneaky and shady as Lord Voldemort’s pet

If you have ever dreamt about the possibility to meet characters from the magical Harry Potter’s world, now you have an opportunity – hackers has recently launched a new ransomware called the Nagini virus. Indeed, the meeting with Lord Voldemort’s pet snake is not a pleasant date. Michael Gillespie, the famous virus researcher, has recently discovered this new ransomware, and it seems malware still under development. The virus is still a mystery for virus researchers; however, the latest information claims that it might be created for testing particular systems. Nagini malware slightly differs from former ransomware viruses. After secretly infiltrating computer’s system, it locks the screen of the infected computer and targets only popular file formats, such as Microsoft Office products, various picture formats, PDF, etc. However, it encrypts only those files that are stored in C:\Users\Colosseum\Desktop\files\ directory and does not append any specific file extension to encrypted files. What is more, it seems that developers are not interested in swindling the money from the victims right now. They do not provide any ransom note and do not ask to pay the ransom in Bitcoins. All they ask for getting back access to a computer is victim’s credit card’s number. Should you tell it? Absolutely not! You should never reveal your personal information to criminals. If this malicious snake sneaked into your PC, do not let it settle here. You have to remove Nagini as soon as it appears on your computer.

Similarly to other ransomware viruses, Nagini infiltrates computer’s system without users’ knowledge and realisation. It usually spreads via malicious email campaigns and exploits its malicious file when a user downloads an infected attachment. Once inside, malware demonstratively announces about its appearance by locking the screen and delivering a picture of Voldemort and his creepy pet. The creators of Nagini virus are called ‘Colosseum.’ It’s still unknown if it’s a group of developers or a single person. However, it doesn’t change the fact that ‘Colosseum’ has some dark and secret purposes. Virus researchers are still analysing this mysterious virus and its features. For example, after successful file encryption, it creates C:\Temp\voldemort.horcrux folder. Why? We still do not have any explanation. We recommend Nagini removal until it hasn’t caused more problems and damage to your computer or personal privacy. For malware elimination, we suggest using reputable anti-malware tools such as ReimageIntego.

The example of Nagini ransomware

What are the distribution techniques of the ransomware?

Nagini ransomware uses the same distribution techniques as other file-encrypting viruses. It travels via malicious email attachments and Trojans. The trickiest way to encounter the virus is to open a suspicious email attachment. Indeed, hackers became good liars and persuaders. They can pretend to be representatives from reputable organizations and rename infected files that they would not raise any suspicion for the victims. One of the ways to prevent ransomware from sneaking into your PC is to avoid opening spam emails and downloading questionable attachments. Also, the virus can travel as a Trojan horse. In this case, you have to be careful while you are browsing the Internet and installing freeware. Stay away from questionable websites, avoid clicking shady ads and for software downloads always choose reliable domains. Lastly, using a professional security program also minimizes the possibility of encountering a hazardous virus.

How to get rid of Nagini ransomware?

The creators of the virus are still developing malware, so you cannot be sure what they are planning to do. Do not risk and remove Nagini immediately. Ransomware-type viruses are one of the most dangerous types of computer infections, so they must be taken seriously. Do not consider eliminating virus manually. You should initiate Nagini removal with a help of professional malware removal tools such as ReimageIntego, SpyHunter 5Combo Cleaner or Malwarebytes. Scan your computer with one of these programs. If you encounter some difficulties, follow instructions provided bellow. Also, you will find instructions how to recover locked files.

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.
