That means encrypted data by two different keys. There are a few ransomwares that will store a victim's master key in the registry and if removed, the next time the computer is restarted, the ransomware could create a new master key and begin encrypting files again. they will run multiple times ensuring repeated infection. Phobos) are very aggressive and do not end on a single run. STOP/Djvu Ransomware) are leaving behind malicious components that will encrypt any new files saved and re-encrypt any files victims previously managed to decrypt.
As such, many victims don't know how long the malware was on the system before being alerted or if other malware was downloaded and installed along with the ransomware which could still be present on the infected computer. In some cases there may be no ransom note and discovery only occurs at a later time when attempting to open an encrypted file. Unfortunately, most victims do not realize they have been infected until the ransomware displays the ransom note and the files have already been encrypted.
The encrypted files do not contain malicious code so they are safe. That also explains why many security scanners do not find anything after the fact. The malware developers most likely do this to make it more difficult for security researchers to find and analyze their malicious payload. Most crypto malware ransomware is typically programmed to automatically remove itself.the malicious files responsible for the infection.after the encrypting is done since they are no longer needed but there are some exceptions.
