System files are usually left alone so that the Operating System can function. The reason is for a ransom message to keep appearing. Efji Ransomware is a modern cryptovirus. Decryption for newly-existing STOP variants is hard to be accomplished, even when malware researchers are on the case of examining the code of the virus. If they cannot find flaws in the code of the virus, it cannot be decrypted. It could take months or even more time until said researchers figure out how to bypass the defense of the virus.
