So somehow I picked up a Trojan, which disabled all keyboard input and when bringing up a browser and trying to type "www.google.com" to see if I could do a search, it immediately closes the browser window.

After about an hour of running malware bytes, the keyboard started working normally again and MB found 3 items, one of which was a Trojan. Should I be fairly confident that I got the thing or do I need to nuke it from orbit and do a clean install? I know you can download a Win 10 install onto a flash drive but how do I reactivate my OS after installing, will it recognize I have a valid license or do I need to copy down the key from somewhere first?

I'd rather not reinstall but I feel like that's the only way to be safe, you know? Going to suck ass downloading Fallout 4 again 🙁

FWIW, I think it came through when Skype asked for permission to add an extension to Chrome, at least that is when I noticed everything went haywire.
