I made a presentation which was very important and was saved on my hard it was very unique and was not available on the Internet or from any other source and was genuinely made by me today I saw my Boss read that presentation in his own laptop I generally use the office Wi-Fi is it possible that he would have taken the data from my hard drive through the Wi-Fi is there any method how can I check the files copied and the time at which they were copied I have enabled password when I turn on my computer but he knew it also my laptop yesterday restarted 3 times with blue screen while connected to wifi ?
