HELP!

Hi guys, I really need your help. Just switched over to macs, and I had 1 big problem already. I used FileVault to incript my home folder, and then I installed norton utilities, and i did a defrag, and all of a sudden, everything was lost, and its in this unrecoverable file called "drsmac.sparseimage". Now since then I unistalled Norton Utils, by dragging it to the trash can, not sure if this unistalled it....now when i use Disk Utility , and try to restore or fix the above disk image, it says there's errors....is my stuff gone for good, or can i restore it somehow, and is the norton fully unistalled? Thanks for any help in advance.

 

no what?
