I seem to have a computer virus (not)

It seems that all of my old photos and files have now disappeared, and we can't find them. I'm talking about the first photos from this blog (not the Japan one, all those photos are safe on cd) So all the photos of Hachiko as a puppy and us walking him for the first time, my friend Sakiko visiting from Japan, New Years eve, Birthdays from last year, all of that is gone gone gone! I don't know what to do, I guess this is why you are meant to back up everything, but geez this sucks. Does anyone know a computer doctor who is cheap and can restore data?


EDIT> Omg we are so stupid. We have spent the last few hours searching for those old photos and files on my computer, doing virus scans that take hours and all came up with nothing when I remembered I didn't even buy this computer until April. All those photos are on Henry's computer. Oh how stupid.

Have you ever done something so dumb?
