Excuse me, that's not true, is it? If yes, what did you do on the computer before the accident, what did you download, and what was unusual? If you think of anything, ask me. If you don't know how it happened, it is recommended to restore the system or reinstall it.

Win78 10 Restore the system, right-click the computer and select Properties, and select System Protection and System Restore on the right. Follow the steps. If you have recovery software, you can also use software and image backup to recover the system.
