In my opinion, changing some of the icons randomly is a “feature” of Win9x. I remember a time when I got a new icon for Control Panel on every boot (Windows 98 SE). Later, it somehow stopped itself… I have no reason thinking that Windows ME should be different.
I.e. if it’s happening in a reasonable extent (just a few icons from time to time), I’d consider it “normal”. If your icons change heavily, then it’s strange - but it’s unlikely to be caused by a virus.
