If you've deleted the files, you'll need a file recovery program to try & get them back! There are links here

Just make sure that you have really deleted them, use your computer's search to look for a few of the file names.

The trash cans next to files means that LW's junk filter has recognised the files as junk (maybe dodgy file size). It's got nothing to do with the recycle bin or anything like that.
