Korea virus Removal Guide
What is Korea ransomware?
Korea ransomware is one of many Dharma ransomware variants that came out in March 2019
Korea ransomware virus is the crypto malware that aims to use various tactics to spread onto machines and once there encrypts files on the computer using the AES algorithm.
Korea ransomware is a cryptovirus that uses AES encryption algorithm for locking victim's files and then marks encoded data by using .[firstname.lastname@example.org].korea file extension. The ransomware typically affects documents, videos, images, archives or even files on external drives and clouds. Since this is one of many Dharma ransomware versions, a ransom message gets delivered in the form of HTML window right after the encryption process. Spotted, as usual, by Jakub Kroustek, Korea ransomware virus is not the only virus that became active in March. In the Twitter post, you can see that Dharma/Crysis virus developers release versions one after the other. This fact only makes the cryptovirus family more dangerous and persistent than before.

Malicious macros deliver the payload to the system directly
Spam email campaigns nowadays achieved another level of malicious and dangerous. Infected email attachments distribute malicious script of trojans or crypto malware including ransomware. The everyday user is not paying enough attention to those notifications so infection can spread further.

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.
