  1. I’ve used SpyHunter to remove this ransomware. But don’t think I’ll wait for the new Kaspersky decryptor to be released. Have Kaspersky recovery tools already proven to be helpful here?

  2. Hello. My files have been encrypted by Ultracrypter ransomware. I found out that there is a new TrendMicro application to recover my files, but it not working properly yet. is it better not to waste time with TrendMicro and use the tools you mention in your article?

  3. Try if it works. As long as there is working unencrypter there is no need to restore from backups/or deleted files.
