Well just delete the norton anti virus and get a new anti virus program and to get your files back this should work if it doesn't come up in recycle bin

1. Open the application you wish to test.
2. Create a test file and save it.
3. Use the application’s File -> Open command to display the Open dialog box.
4. Locate your test file in the list, right-click the file and choose Delete from the pop-up menu.
5. Check the Recycle Bin to see whether your file has been placed there

I hope that helps.
