Suddenly a website popped up on chrome tried to close it & there was a pop-up closed it again; then my firefox browser was refreshed & a NEW “hibro.txt” file was created on the desktop. Opened the txt file and they were addressing me & talking about how good of a gamer I am…

SO can you please explain HOW WAS the .txt file created by the hacker & HOW THE HELL did they know I’m a player of xyz game?? COULD THEY HAVE ACCESS of my files, folders and family pictures too? PLEASE HELP and KINDLY CLARIFY MY DOUBTS!
