I installed Avast AV when Norton expired. In order to activate the internet security stuff, I had to install the upgraded library file, blah, blah, blah. To do this, I had to show hidden folders. Having only recently begun my foray into Windows 7 (coming from XP), I was flying a bit blind. I must have hit the wrong thing. After I was able to see hidden folders, install the library file to Avast and continue on with the reboot, the desktop came up wiped clean of my documents/pics, etc and my C:\Users\Susan folder has disappeared and is now called Public. Next, I thought I may have switched my user from Susan to Public, but I have not.
I can find it in [shell:UsersFilesFolder] under Custom, but I cannot open the location. It would appear to have all my stuff (libraries are listed, but can't see past that). I can see it in "Choose Search Location" but cannot open it.
What did I do? I am so confused and feeling like a complete novice at this point....
