There are certain key generators for CyberGhost sailing through the Internet, some of them hosted at places, you know exactly what to expect from (nothing good) and some of them promoted on more un-suspicious platforms like Youtube.
Either way, as you already might suspect, a key generator does not only sometimes do, what you run it for (generating a key), but also checks out your PC and adds a few codes here and there. Key generators are the perfect tools for transporting Trojans and other malware and one doesn't even have to convince people to use it.
So, please beware, there are no official CyberGhost key generators out there. And of course, we neither accept nor support keys obtained from a key generator.
