Question : Cannot Access Application Data

Hi,
So a user in my organisation decided to click on a virus email and is unable to login to XP even in Safe mode or System Restore. I have the drive out of PC and can access Documents and Settings however I cannot access the Application Data file to extract his email PST file.
I keep getting Access is Denied error appear and the file size says that it is empty.

Can anyone help me work out a way to get into this folder at all? Need to get emails then set them up onto the Exchange Server.

Thanks!
