My brother's laptop is hacked by an unknown person who has had no physical access to his computer. there is strong evidence as files from the computer have been deleted, webcam starts up on its own and constant messages via a program like cmd requesting presence on skype. moreover, that person has added my brother on skype, openly claiming to be the hacker.
how do i stop him and undo the damage that has been done?
