3 second delay after clicking on folder

There is a 3-4 second delay after clicking on c:\documents and settings and c:\program files .... this does not seem to happen on any other folder ... and it doesnt seem to happen in other user profiles or when the left pane in my computer is switched off ... even after a full scan using kaspersky standalone scanner the problem persists ...

Thnx in advance ...
