Wrui ransomware is an incredibly dangerous computer malware that encrypts all personal data and demands a ransom in Bitcoins to restore access to it. This cryptovirus can infect Windows computers in any country or continent. Once it does, all files are renamed by appending a .wrui extension to their original filenames. Please note that the file contents aren’t changed, but you won’t be able to use any of them until a specific decryptor is used.
