Sorry, the extension of the files are .happydayzz with three “Z”, for this inconvenience I think this method does not work for me. Do you know any decrypter for .happydayzzz? (sorry for my English).
Example file: [] .FA80E5467292B179AAD3C0743D1E16D71E412C4F85.happydayzzz
Yes, i have written in the answer to Maravento with alternative link.
Sorry, I do not see any links. I have the original file and the encrypted file but I guess this method does not work because the encrypted files have the extension. .zzz (3z)
sorry. what link????. This method does not work because the file ends with .happydayzzz (not happydayzz) 3z

you found a some solution?… hablas español?
Hola Luis: Aun No, solo nos queda aguardar y buscar otras alternativas (guarde por separado mis archivos encriptados) y bueno instale un nuevo antivirus para que este tipo de casos no vuelva a suceder.
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)
