Retis virus Removal Guide
What is Retis ransomware?
Retis ransomware gives 24 hours to pay the ransom
Retis virus belongs to the ransomware family since it is designed to encode data on the victimized computer. Following the encryption, it appends .crypted extension at the end of the filename and changes the wallpaper to the ransom note named RANSOM.png. While this crypto-malware initially targets French people, experts note that it might be soon updated to spread worldwide.
The authors of this file-encrypting virus identify themselves as Hack Lab by RETIS on the ransom note. It is believed that they employ sophisticated AES algorithms to encode information and profit from inexperienced computer users. However, it is currently unknown how much money they demand to pay for Retis decryptor, and there are no contact emails indicated.
This suggests the ransomware might be still under development and you have a chance to recover your files easily if you perform Retis removal as soon as possible. Note that hackers aim to extort as many people as possible. Likewise, there is a strong possibility that they will update it soon to make even more damage.
Retis ransomware encrypts data and gives 24 hours to pay the ransom or the decryption key will be deleted from the server.
The translation of Retis ransom note:
Your office, photos, data and other essential files were encrypted with a robust algorithm,
and a unique key is generated for this computer.
The secret key for decrypting your data is stored on the Internet server,
and no one can decode your files until you pay to receive it.
You have 24 hours to send us the ransom.
WHEN THE TIME ENDS YOUR KEY WILL BE DELETED FROM OUR SERVERS,
AND YOU MAY NOT REACH YOUR DATA.
People are urged to pay the ransom in 24 hours, or their decryption key will be deleted from the servers. As a result, victims are claimed to be unable to recover files and access their data. However, we still suggest you remove Retis since our team has prepared several effective methods how you can alternatively retrieve your data without paying the ransom.
Use ReimageIntego to get rid of Retis ransomware right when it infects your system. You can use the guide below which will briefly explain you what to do step-by-step and suggest alternative recovery techniques to regain access to your files and valuable information.
Ransomware distribution: spam emails, P2P networks, malware-laden ads
The most widely used way to distribute file-encrypting viruses is to send emails containing malicious attachments to the potential victims. Usually, the letter looks genuine and supposedly holds “very important” information. Likewise, people are encouraged to click on the attachment/link to receive the invoice or another document. If they do so, the ransomware infiltrates on the system.
Moreover, criminals tend to put obfuscate executables of the malware on peer-to-peer networks where people share files. To trick their targets into downloading them, they imitate popular software or their updates, such as Adobe Flash Player. Even though the file looks like a legitimate program, it is merely a deceptive appearance hiding the ransomware inside.
Also, since it is now almost impossible to avoid ads, it becomes harder to determine their origins. Therefore, hackers try to benefit from the advertising by placing malware-laden ads which either lead to their managed pages or automatically start ransomware installation. Thus, stay away from advertisements all the time.

How to prevent from getting ransomware
Do not let government spy on you
The government has many issues in regards to tracking users' data and spying on citizens, so you should take this into consideration and learn more about shady information gathering practices. Avoid any unwanted government tracking or spying by going totally anonymous on the internet.
You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using Private Internet Access VPN.
Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.
Backup files for the later use, in case of the malware attack
Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.
When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
