history

When i click on the history button or open the history
toolbar the windows folder is displayed. I checked the
c:\documents and settings\%username\history file and it
displays the correct info. It seems like a virus or some
kind of ad/spyware has changed the link in ie to diaplay
the c:\windows folder insted of the history file. Wher isn
the registry is this information stored? Or where can this
be fixed. One other thing this only effects one users
profile.
