It has become an annoyance to me now. I have photoshop 7.0. Sometimes I save ".psd" files on my desktop and when I click on something else, it turns the .psd icon to whatever I clicked. I can still open it with photoshop but it's just annoying because the icon keeps changing to something that it shouldn't be. I'm not sure if there's a spyware or virus involve but I scanned my computer recently and deleted all viruses and wares that was found.
