So I've recently got a very targeted virus and spyware on my system and apparently it infected everything in its vicinity including the BIOS and routers. Even clean installing doesn't help, the virus has been there for months and now it knows my account passwords when I logged into Microsoft after the clean installation.
So therefore I've been thinking to completely wipe out every possibility of the virus existing and for that I need to convert every writable bit in the system and its extensible devices to 0. I want to know if that's possible even if it meant keeping the laptop in the refrigerator. If there are other ways to remove the malware, I'm listening but also please answer the original question as it might help someone in the future.
