Desktop Icons were removed?

[kjunkies]

I saved the 3.318 exe file to my desktop. This is when the error ocurred & then somehow the old exe file removed itself along with half of my desktop icons... would this have something to do with the bad file..?? I was preparing new books and was working on it through a word document on my desktop - this has now vanished & I have tried search & temp files but so far have not located it...?? Luckily there was an Auto Recovery done not long before this so I haven't lost toooo much...
