Firstly Stressed Mum, I would tend to go with Epsons assessment of your scanner, of which by the sounds of it you have accepted by buying a new one.
to search for the photos go to Search and type in the following: .jpg* Once that search has finished and you have restored those, do anothere search for: .bmp* and do the same with the results.
To uninstall hard to remove software download and run Ccleaner,click here for the download from FileHippo link. Open Ccleaner and open the Tools menu to unistall the software.
Hope that is of some help?
