Need Help To Bring Invisible Windows Back On Screen

OK, I have problem, thanks to my 7 year old!
She turns on PC and the same time my antivirus program
Starts updating files, instead of waiting 2 minutes she tries to
Connect to internet (by default Firefox. naturally it’s a bit slower
Then usual, but she tries to open another one and another one
When windows start to appear, she drags them out of sight
She use popup window to play her game and when she done and
Close this window the rest of windows visible only on toolbar
And I not able to bring them back!
I try everything I know (unfortunately its not much!) restore,
Move, resize, even system restore, but window still out of my sight!
I have to use now IE.
I hope that somebody can help me!
Thanks!
