Remove Artemis ransomware (Virus Removal Guide) - Decryption Steps Included

removal by Julie Splinters - - | Type: Ransomware

Artemis ransomware is a computer infection that tries to get your money in exchange for a data decryption tool

Artemis ransomwareArtemis ransomware is a virus that encrypts personal files.

Artemis ransomware is a new version of PewPew ransomware[1] that locks personal data and demands money from those who want to get a decryption key. Moreover, this virus also deletes system restore points and shadow copies of files to prevent victims from restoring their files easily.

Artemis virus employs a powerful encryption algorithm[2] to lock all personal files: documents, videos, pictures, music, etc. All affected files get .artemis extension, accompanied by the victim's ID and a contact email of the attackers. Thus, the modified file names look longer than those of other ransomware. For example, if your picture was named “one.jpg,” it becomes “one.jpg.id-C279F237.khalate@tutanote.com.artemis” after encryption.

Besides that, malware delivers a ransom note in a pop-up window format, titled “encrypted.” It discloses what happened to personal files and claims that an email to khalate@tutanota.com should be sent to cooperate about the size of the ransom and other details.

This threat not only uses a text file to explain what happened to all personal data but also shows a pop-up note from cybercriminals. According to hackers, the victim can send up to 5 locked files (no valuable information should be included), and they will decrypt them to prove that the decryption key really exists.

Ransomware[3] message presented in “info-decrypt.hta” file reads the following:

Methods how to recover .artemis files

In most cases, victims believe that they can unlock files and remove .artemis extension by deleting ransomware from their computers. But in reality, all affected data remains locked even after the malware is removed.

Unfortunately, there is no way to decrypt .artemis files without backups or paying cybercriminals. Not many users practice data backup procedures and end up thinking about paying ransom money. However, you should remember that paying ransomware developers is not advisable. They can deceive you and run away with your money without giving the decryption key.

Bonus: Recover your data

Guide which is presented above is supposed to help you remove Artemis from your computer. To recover your encrypted files, we recommend using a detailed guide prepared by 2-spyware.com security experts.

If your files are encrypted by Artemis, you can use several methods to restore them:

Try to use Data Recovery Pro if you want to recover files:

In some cases, Data Recovery Pro might be able to find unaffected file copies on the hard drive.

  • Download Data Recovery Pro;
  • Follow the steps of Data Recovery Setup and install the program on your computer;
  • Launch it and scan your computer for files encrypted by Artemis ransomware;
  • Restore them.

Try to use Windows Previous Version feature too:

Sometimes it is possible to restore files one by one if you had System Restore enabled before the infection managed to infiltrate your computer.

  • Find an encrypted file you need to restore and right-click on it;
  • Select “Properties” and go to “Previous versions” tab;
  • Here, check each of available copies of the file in “Folder versions”. You should select the version you want to recover and click “Restore”.

ShadowExplorer might be useful:

Shadow Explorer should be able to recover your files if the Artemis ransomware failed to delete Shadow Volume Copies.

  • Download Shadow Explorer (http://shadowexplorer.com/);
  • Follow a Shadow Explorer Setup Wizard and install this application on your computer;
  • Launch the program and go through the drop down menu on the top left corner to select the disk of your encrypted data. Check what folders are there;
  • Right-click on the folder you want to restore and select “Export”. You can also select where you want it to be stored.

Unfortunately, the decryption tool is not available.

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from Artemis and other ransomwares, use a reputable anti-spyware, such as ReimageIntego, SpyHunter 5Combo Cleaner or Malwarebytes

Stream videos without limitations, no matter where you are

There are multiple parties that could find out almost anything about you by checking your online activity. While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.

Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful Private Internet Access VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.

Data backups are important – recover your lost files

Ransomware is one of the biggest threats to personal data. Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.

While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as Data Recovery Pro can also be effective and restore at least some of your lost data.
