I recently found the program Recuva from Piriform. I ran the scan for pictures and was surprised at the "deleted" pics in found on my computer. Pics I never downloaded. Pics that must have been in the background of web pages I have visited, image searches etc. I see in the progy I can overwright the files to make them unrecoverable, but is it possible to fully remove the files (pics, docs, vids, etc.) so they don't keep showing up in a scan?
