Artemis virus Removal Guide
What is Artemis ransomware?
Artemis ransomware is a computer infection that tries to get your money in exchange for a data decryption tool
Artemis ransomware is a virus that encrypts personal files.
Artemis ransomware is a new version of PewPew ransomware 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 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.firstname.lastname@example.org” 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 email@example.com should be sent to cooperate about the size of the ransom and other details.

How to prevent from getting ransomware
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.
