Drives not opening

[sravan]

I have xp sp2 in my system. Whenever I try to open the logical drives they are not opening and open with dialog box appears. If I select IE they can be opened.
Also I am not able to see hidden folders in this sys. I I change the option in Folder options nothing happens and the option is reset as "don't show".
I have scanned(boot time scanning) with Avast anti virus (fully updated).
But the problem is not solved. I am attaching the error pic
Plz help me
