Yesterday morning my laptop was working fine (I have Windows 7 Home Premium), and later that day when I signed in to my account everything was gone. My background image is gone, some of my applications are gone (like Spotify). and most importantly all of my files are gone. I cant see any of my pictures or text documents, nothing. So I ran SuperAntiSpyware and MalwareBytes in safemode to no avail. I also tries unhiding files, but when I go through the process of unhiding files and get to the View button, there are no options for me to uncheck hidden files. It's just a blank box.
I'm not good with computers, so I would really appreciate detailed instructions on what I should do to fix this.
