ARTEMY virus Removal Guide
What is ARTEMY ransomware?
ARTEMY ransomware is a file locking malware that targets Russian users
ARTEMY ransomware is a file locking virus that comes from Scarab family
ARTEMY ransomware is a data locker that was first spotted by the security researcher Amigo-A at the end of February 2019. It comes from Scarab virus family and targets Russian-speaking users, similarly to other variants like Scarabey, Osk, and Bomber. The cyber threat uses the AES encryption algorithm to lock up documents, databases, pictures, music, videos, etc. and appends .ARTEMY extension and scrambles names of data, consequently preventing victims from opening any files that are modified that way. Scarab-Artemy virus then generates a ransom note КАК ВОССТАНОВИТЬ ЗАШИФРОВАННЫЕ ФАЙЛЫ.TXT (“how to recover encrypted files.txt”), which explains to users how to proceed next. Allegedly, the decryption key can be purchased for an undetermined amount of Bitcoin, after contacting cybercriminals via emails email@example.com, firstname.lastname@example.org, or email@example.com. According to researchers, discounts up to 80% are offered to pregnant women, the unemployed, the disabled, and the poor. However, paying ransom is not recommended in any case – victims should remove ARTEMY ransomware and use alternative file recovery methods.
|File extension||[scrabled file name].ARTEMY|
|Ransom note||КАК ВОССТАНОВИТЬ ЗАШИФРОВАННЫЕ ФАЙЛЫ.TXT|
|Contactfirstname.lastname@example.org, email@example.com, or firstname.lastname@example.org|
|Related files||osk.exe, 27.02.19.scr|
|Distribution||Malicious spam emails, fake updates, weak RDP, etc.|
|Elimination||Use anti-malware applications like ReimageIntego, SpyHunter 5Combo Cleaner, or any other software that can recognize the infection|
ARTEMY ransomware is most likely distributed with the help of malicious phishing emails, repacked installers, unprotected RDP configuration, fake updates, torrent files, or similar methods. To stop the infection before it locks data, you should always keep a security application running in the background. For additional defense methods against Scarab-ARTEMY, check the second section of the article.
Once ARTEMY virus is extracted on the host device, it performs various changes to it, such as:
- Disables Windows auto-repair function at the startup;
- Removes Shadow volume snapshots;
- Creates and modifies Windows Registry keys;
- Opens MountPointManager;
- Spawns and kills many processes, etc.
Once system modification is complete, ARTEMY ransomware begins file encryption procedure and drops the ransom note to the affected folders. The files are modified by using the encryption algorithm; for example, picture.jpg is turned into BUXjzYpCJ7O5zQH2s19jyqLbr.ARTEMY. This process consequently prevents users from accessing any data – only the decryption tool would be able to decode it.
ARTEMY is a ransomware-type virus that targets Russian users
Allegedly, ARTEMY ransomware authors claim that unemployment made them engage in this illegal business. Whether it is true or not is a different matter, but it does not change the fact that what these people are doing is money extortion – it is highly illegal and harmful to innocent users. Additionally, according to the ransom note, the offered discounts can only be applied once legal documents are provided.
Do not send any type of documents that confirm your identity – the sensitive information can be stolen and sold on the black market for profit. Instead, focus on ARTEMY ransomware removal. For that, you will have to employ anti-virus software that is capable of recognizing the threat. We recommend using ReimageIntego or SpyHunter 5Combo Cleaner
Avoid ransomware viruses by using precautionary measures
Ransomware developers usually take advantage of several malware distribution methods, such as spam emails, malicious executables hosted on hacked sites, brute-force attacks, botnets, and other techniques. Therefore, getting infected with ransomware might be easier than one might think.
You should never ignore security tips from industry experts:
- Download and install a reputable security application;
- Enable Firewall;
- Always patch your system with the latest security updates;
- Do not click anything on suspicious websites;
- Avoid high-risk sites, such as porn, gambling, torrent, etc.
- Scan all executable files or suspicious URLs with tools like Virus Total;
- Use ad-block (don't forget to use exclusions for sites you want to support);
- Beware of spam email attachments and hyperlinks inside.
Terminate ARTEMY ransomware virus infection based on our instructions
Without a doubt, you should remove ARTEMY ransomware as soon as possible and never contact cybercriminals. For that you will need to employ reputable security application, such as ReimageIntego or SpyHunter 5Combo Cleaner – these tools recognize the threat as TR/AD.ZardRansom.grojy and Ransom.Scarab.

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from ARTEMY and other ransomwares, use a reputable anti-spyware, such as ReimageIntego, SpyHunter 5Combo Cleaner or Malwarebytes
How to prevent from getting ransomware
Choose a proper web browser and improve your safety with a VPN tool
Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online. One of the basic means to add a layer of security – choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features. However, if you want true anonymity, we suggest you employ a powerful Private Internet Access VPN – it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.
Lost your files? Use data recovery software
While some files located on any computer are replaceable or useless, others can be extremely valuable. Family photos, work documents, school projects – these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur: power cuts, Blue Screen of Death errors, hardware failures, crypto-malware attack, or even accidental deletion.
To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, Data Recovery Pro can be your only hope to retrieve your invaluable files.
