Hello, Kripelex, and welcome to Sysnative Forums.
There is evidence that you are not only using pirated programs, but you are also using a method to bypass activation for other programs. The most concerning, however, is that you have activation issues regarding the operating system (Windows Enterprise is used for business computers and not for individuals). All these are more than enough to give you a really bad infection, and that is what you are experiencing right now.
Having said that, we can only assist you if you legally activate your Windows at the first place. On one hand is the ethical part, on the other is the Forum's rules. Plus, it's a waste of time trying to clean a system which is not activated with a genuine license, and with illegal software installed. It will get infected again, soon or later, and this is not a possibility. It's a fact.
There are reputable sites that sell genuine licenses at a low price these days. If you like, I can recommend you one.
Please, let me know about your thoughts.
