Dragging the program or its folder to the recycle bin can be a very bad decision.

  • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
  • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce

You can access them by opening the Windows registry editor and deleting any values, created by HappyDayzz there. This can happen by following the steps underneath:

2. When you open it, you can freely navigate to the Run and RunOnce keys, whose locations are shown above.

3. You can remove the value of the virus by right-clicking on it and removing it.

          lol, algo así hice… le puse otro HDD a mi laptop para seguir trabajando en ella, también usare un programa de recuperación de archivos eliminados (recuva, wondershare data recovery, etc) para recuperar los archivos eliminados por el ransomware en el disco infectado y bueno guardare ese HDD hasta encontrar una solución en el futuro para desencriptar todo(ojala cercano).

          Si encuentras algún método coméntalo por favor.

    Muy buen artículo, pero tiene un solo problema. “Arrastrar y soltar el archivo cifrado y el archivo original junto al descifrador” (el archivo original no existe porque fue cifrado por el ransomware)

      Hello, You can look for original files in multiple different Default Windows picture folders, for example in %Windows% or %System32%
