My sonslaptop (Windows 7 Home) had the Ransom Trojan. The Trojan is gone but he also deleted access to Administrator whentrying to get rid of the ransom screen. He only has access to Guest and cannotcreate another administrator account.
1. Trying to show the hidden administratoraccount in safe mode but it says access denied.
2. Adding a user at the command promptbut I get access denied.
3. Using the backup CD but I get anerror message.
Would anupgrade to Windows 8 work?
