Manually Removing ATM Deluxe 4.0x or ATM Light 4.0x for Windows 95 or Windows 98

Depending on what was installed, not all of the second link will apply - in fact I doubt is was 4.x .

Sometimes you'll get this kind of thing from older graphics or drawing programs - though I'm guessing you got it from the Acrobat 3.x install.
