XP disk drive problem

I have a slight problem.

When I click on D: I get this dialog box appear. This didn't happen initially. My AV software started noticing trojans on pc and soon after I would get this dialog box appear whenever I wanted to open a disk drive.

I reinstalled XP and have the same issue.

Sorted.

Installed 'autorun eater' and it's fine now.
