  • Key generators (also known as Keygens).

Nqhd Ransomware – What Does It Do?

  • Videos (.mp4, .avi, etc.).
  • Archive file formats (.zip, .rar, etc).

    1. Ventsislav Krastev (Post author)

      Hello, you can choose among any anti-malware programs out there, not just SpyHunter. However, the research team behind the software always keeps SpyHunter updated to cover the latest STOP Ransomware threats, like NQHD virus and is fully capable of removing it. It also has a Free removal option, but it is delayed removal, so you will have to wait a bit before the removal takes place.

    1. Ventsislav Krastev (Post author)

      It is possible if your decryption key is offline. In case it is, you can try the STOP Decrypter in the video on the “How to Remove” section. If the key is online based, it is much difficult to decrypt the files, but you can still use data recovery and other methods we have mentioned in the “try to restore” section.
