I have had 3 hidden file icons appear on my desktop.

One is C:\Documents & Settings\myname\Desktop\Templates (read only & hidden
in a see-through folder icon)
C:\Documents & Settings\myname\Desktop\%SystemDrive% (an actual opaque
folder icon)
C:\Documents & Settings\myname\Desktop\ZbThumbnail (in a see-through folder
icon) This is software (ZoomBrowser) provided by Canon for use with their
digital cameras.

I have no idea why these files are suddenly showing on my desktop as I have
not knowingly placed them there.

Any idea why these have suddenly appeared? The forums have always been very
helpful in the past, thanks in advance.
