iexplore.exe

I'm having a problem with iexplore.exe using
too much processor, is there a fix for this.
Is it a bug of some kind.
I went to google and tried to find a cure and when I tried to delete it
using the instructions, it disappeared before I could.
I know it sounds strange but I'm at a loss.
Anybody know a good removal tool?
I already used Norton and their deep search tool to no avail.
