Good day, thank you for this forum,awesome. I was infected with the STOP- .codnat extension on a 1 TB External,had to format my Alien-ware 17R3, downloaded  STOPDecrypter, it runs but needs a key for ID:Qfu13uHgAsRudCYCjYn4qU0HmlNTMv2NBe7wE9zi, states no key for this ID, can this be achieved,tried Spyware, but to no prevail. This would be a Blessing.

Regards

Salmon
