You have done a wrong thing by installing a cracked copy of Windows 10 on your system. The ones who create cracks are experts at software engineering and reverse engineering and they can add malware, spyware, and any other virus in the crack easily. Most probably they add malware but in a way that's 100% undetectable by any available anti-virus program because the crackers know that the ones who use Windows OS are more likely to spend money online using credit cards and other stuff.

I believe that you wallet isn't safe at all, I recommend you to wipe out your entire drives and then install Linux based Distro that's freely distributed and doesn't need any kind of crack in order to activate it. The Linux is the safest operating system out there and anyone who uses Linux is far more safe than the ones who rely on Windows OS.

I know that most users like Windows OS because it's easily to use but these days there are many Linux distros that can be used be non-tech guys. The distros like Linux mint and Lubuntu are the ones that any user can use without much hassle. The best thing about Lubuntu is that it's less resource intensive and even runs of intel atom based laptops flawlessly.
