I've made clean installation of Windows 2-3 times since I've entered the passwords last time.
I hope the investigation of this case can improve the Bitcoin world and can prevent such incidents in future
Did u use any external devices (usb) which were used on the (maybe) compromised system after the clean installation?
Or did you only use new usb sticks / no at all?
If your going to get BTC again.. get a hardware wallet and initalize it on a linux distrib.
