> The problem was created because of a Ransom attack
My guess is the attack crippled your user account. At what point are they demanding the ransom? At the Welcome screen? IAC, if I am correct the SAM hive, and perhaps others as well, is corrupted and you must either revert to a restore point, use last known good config, or restore the registry manually the way I described (and maybe not just the SAM file either, though I would start there). Best would be if you keep up to date system images offline. The alternative would be to try to rescue data and settings, if they're not backed up, and then do a fresh install. At least, that's how I would approach it. Perhaps a malware expert would have a lower level way to solve the problem.
