Shortcuts and files lost in documents -Windows vista

Hi,

I am facing some troubles on my hard disk.In my documents, music , pictures & some folders have become shortcuts and some files are lost, but rest things on C drive seem to be ok. I ran avg, it showed few trojans, i moved them to vault.attrib command doesnt work or seems to show no result. Can you please suggest on how to recover my extremely imp files now? 
Please help.

I didn't find the right solution from the Internet.
