Black Dots On Desktop Background?

The thread I'm referring to is called "Black Dots On Desktop Background" and it was posted by charleyvonne. I quote it below. I recently downloaded a wallpaper changer program called Winvista. As soon as I started to play with the different wallpapers on my desktop, I couldn't help but notice that it had completely cocked up! It seems rather odd, behind the display picture there are a series of grid formad dots, very small and regemented. These move around when I open windows over them or when I select desktop icons. I had a go at changing my resolution, display settings, themes, effects and tried using different background pictures. I've restarted a few times and have selected to use different solid colours, but these dots don't budge. The program isn't running now, but I still have the dots! I could try to put up a screen cap of my desktop if it helps?

I downloaded Winvista, a wallpaper changer program, just as this member did, and then black dots appeared on the background colour of my desktop. It is very annoying, and I didn't experience the problem until I downloaded Winvista. I have deleted the Winvista program, since it didn't really work for me anyway, and also I've tried system restore- with no change.I am VERY anxious to correct this issue. Can someone give me some advice? I've checked the advice given on the outdated thread- none of it seemed to offer the solution I need. Also, in the outdated thread charleyvonne didn't seem to find a solution either.
